The Cartels and Leniency Review: Portugal

Enforcement policies and guidance

i Legal framework

The legislation regulating cartels and leniency in Portugal is the Portuguese Competition Act (the Competition Act), which was last revised in 2012.2 The Portuguese Competition Authority (AdC) has adopted several notices and guidelines relating to various procedural aspects, in accordance with the European Commission's guidelines, including, in particular, the Guidelines on the Calculation of Fines,3 the Notice regarding Immunity from a Fine or Reduction of Fines4 and the Guidelines on the Handling of Antitrust Proceedings.5

The term 'cartel' does not appear as such in the Competition Act, although cartel activity, along with other collusive agreements and concerted practices, is prohibited under Article 9 (equivalent to Article 101 of the Treaty on the Functioning of the European Union (TFEU)). There are, however, attempts to define cartels in Portuguese legislation. Article 75(1) of the Competition Act, in establishing the leniency regime, considers that the leniency provisions are only applicable to agreements and concerted practices among competitors whose object or effect is the restriction of competition by, inter alia:

  1. directly or indirectly fixing sale or purchase prices or any other transaction conditions;
  2. limiting or controlling production, distribution, technical development or investment; or
  3. sharing markets (including bid rigging), through import or export restrictions or through anticompetitive actions against other competitors.

An identical definition was included in Law No. 23/2018 of 5 June 2018 (the Private Enforcement Law),6 which transposed the Damages Directive,7 making, furthermore, reference to the 'secret' nature of cartel conduct.8

Prohibited agreements or decisions under Article 9 are null and void, unless they fall under the scope of Article 10 of the Competition Act, equivalent to Article 101(3) of the TFEU (i.e., if it is demonstrated that they contribute to improving production or distribution of goods or services or to promoting technical or economic progress). In fact, Article 10(3) of the Portuguese Competition Law makes an explicit reference to the EU block exemption regulations to be used as relevant assessment framework by the AdC, even in purely internal cases, with no impact on EU commerce.

In Portugal, cartels are sanctioned as misdemeanours, administrative offences,9 with fines of up to a maximum of 10 per cent of the offending undertaking's turnover in the year preceding the decision.10 Under the Competition Act, individuals with management, directing and monitoring functions, in certain conditions, are also liable to be sanctioned for competition law infringement.11 The Competition Act also provides for ancillary penalties corresponding to the prohibition on taking part in public tenders for a two-year period for of competition law infringements concerning these competitive procedures (see Section V).12

The Competition Act also includes the possibility to benefit from immunity from fines or a reduction in fines in cartel cases (Article 70) under the terms of the leniency programme (Articles 75 to 79), according to which, undertakings or individuals taking part in the practices described in the provisions referred to may apply for immunity or a reduction of a fine if they recognise their participation in the breach and provide concrete evidence that allows the AdC to establish the existence of the alleged infringing conduct (see Section IV).

The Competition Act also provides for a settlement mechanism allowing a reduction of a fine before and after the statement of objections.13 There is also the possibility of closing investigations with conditions, such as commitments submitted by parties, under Article 23 (see Section V).14 In this case, the investigative process can be reopened within two years if the alleged infringing conduct resumes.

The competition provisions, in particular those related to cartel prohibition, are enforced by the AdC, by the specialised Competition Regulation and Supervision Court and, when related to issues not exclusively pertaining to competition law, by other civil and administrative courts.

The AdC is an independent administrative body in charge of the public enforcement of competition law in Portugal, without exception to any sector of the Portuguese economy. When communicating its competition policy priorities for 2020, the AdC declared that it 'maintains as its priority the detection, investigation and sanctioning of practices that distort the functioning of markets, with a particular focus on cartels'. To this end, the AdC seeks to increase its capacity for detection and investigation of anticompetitive practices, namely through complaints by consumers and other market players, and through its leniency programme.15 A concrete example of the AdC's goal to increase its capacity for detection and investigation are the proposed modifications to the Competition Act resulting from the preparation of the transposition of the ECN+ Directive.16 In fact, the AdC has been heading the transposition of the ECN+ Directive into Portuguese law and has already submitted to the Portuguese government the final draft transposition proposal. In addition to the transposition of the Directive's provisions, the AdC also took advantage of this opportunity to propose some adjustments to the existing Portuguese competition law framework, potentially leading to an increase of the AdC's investigative powers and access to evidence.17

The Competition, Regulation and Supervision Court is a specialised court incorporated in 2012, competent to hear the appeals of decisions of sector regulatory entities, as well as of the AdC. It is also the competent court for private enforcement cases exclusively based on competition law infringements (see Section VII).

ii Decision practice

The powers of the AdC in terms of cartel investigation are provided for in the Competition Act and subsidiarily regulated by the legal framework applicable to misdemeanour offences, which could grant the investigated entities some additional protection in terms of rights of defence.

The AdC's decisions may be appealed to the Competition, Regulation and Supervision Court.18 The decisions of this Court may also be appealed, at a second level, to the Lisbon Court of Appeal, which has an autonomous section on intellectual property and competition, regulation and supervision. When the appeal is limited to issues of law, it shall be lodged with the Supreme Court. There is also the possibility of appealing to the Constitutional Court for the purpose of examining a question of unconstitutionality raised within the process.

The AdC's most significant cartel cases to date are the Glucose Diagnostic Strips cartel,19 the Salt cartel,20 the Flour Mills cartel,21 the Catering Services cartel,22 the Polyurethane Foam cartel,23 the Cleaning Companies cartel,24 the Office Consumables cartel,25 the alleged Train Maintenance cartel26 and the alleged Insurance cartel.27

In 2019, the AdC made extra efforts to detect and investigate cartels, and some relevant landmarks were reached, such as the first sanctioned cartel in the financial sector (the Insurance cartel),28 which marked the biggest fine in the history of the AdC (a record that has since been exceeded in several cases (see Section IV.ii)). The undertakings participating in the Insurance cartel were sanctioned for alleged market sharing and price coordinating concerning the sale of workplace accident, health and motor insurance to large corporate clients. The purpose of this coordination was apparently to allow the incumbent insurer to retain the respective client. This cartel was sanctioned following a leniency application, and led to a total fine of €54 million,29 including the application of fines to two directors and two administrators.30

In September 2019, the AdC fined 14 banks a total of €225 million (with the highest individual fine at €82 million) for an alleged concerted practice corresponding to the exchange of sensitive commercial information on loans. Although the facts were not analysed as a cartel, the proceedings were initiated subsequent to a leniency application from a first applicant, which benefited from a full exemption of the fine, and a second applicant, which was rewarded with a 50 per cent reduction of its fine.31

Also, in December 2018,32 April 2019,33 June 2019,34 and March 202035 the AdC fined five undertakings and five directors and administrators a total of over €3.4 million for participating in the Train Maintenance cartel that focused on public tenders for railway maintenance, including practices that could be characterised as bid rigging.36 The proceedings were concluded earlier than anticipated (between December 2018 and June 2019) for three of the involved undertakings, because of their collaboration with the investigation in admitting their participation in the cartel, and the avoidance of judicial litigation by using the settlement procedure. The percentage of fine reduction is not clear from the publicly available information, but, typically, the AdC will allow the 10 per cent reduction set forth at the EU level. On the other hand, the two companies that did not use the settlement procedure were, in addition to the fine, sanctioned with a two-year ban from participation in public tenders (see Section V).

In 2020, according to public information, the AdC initiated various proceedings related to cartels, having issued six statements of objections for alleged anticompetitive agreements, price-fixing and hub-and-spoke arrangements, in the food retail,37 telecommunications38 and land surveying39 sectors. In 2020, the AdC also imposed the highest individual fines ever, first, in the beginning of December, by sanctioning a telecommunications operator with a fine of €84 million for alleged market sharing and price-fixing of mobile and fixed telecommunications services.40 It did so again, at the end of December, by sanctioning six large retail food chains, two suppliers, a board member and a director for alleged price-fixing through hub-and-spoke arrangements with a total fine of €304 million, including the highest individual fine of €121.9 million.41

In short, the AdC has, in recent years, been particularly proactive in the investigation and sanctioning of anticompetitive practices, having issued, according to publicly available information, between 201942 and 2020,43 12 sanctioning decisions with fines totalling €733 million, one decision with remedies (bakery sector) and 11 statements of objection, as well as conducting dawn raids in, at least, four investigations and receiving three leniency requests.

Cooperation with other jurisdictions

The AdC cooperates with the European Commission and other national EU competition authorities throughout the European Competition Network (ECN) and within the Network of Competition Authorities.

As regards the application of Articles 101 and 102 of the TFEU, the AdC has established formal cooperation mechanisms provided for in Regulation (EC) No. 1/2003, as well as informal cooperation and exchange of information within the ECN.

In this context, under Regulation (EC) No. 1/2003, the AdC formally cooperates with other national competition authorities and the European Commission in antitrust proceedings. According to the AdC's Annual Report,44 in 2019 the AdC participated in:

  1. 28 formal and informal cooperation meetings of the ECN working groups, notably on cartels and restrictive practices; and
  2. 12 oral hearings and meetings of the advisory committees on restrictive practices and merger control.

Moreover, the AdC also cooperates with national competition authorities in the context of other international organisations and networks, including the International Competition Network (ICN) and the Organisation for Economic Co-operation and Development (OECD) Competition Committee.

The current president of the AdC, Margarida Matos Rosa, has become an elected member of the ICN Steering Group for the 2019–2021 mandate, which is the first time the AdC has been elected as an effective member thereof. As a member of the ICN, the AdC contributes to its working groups, including the Cartel Working Group.45

Within the OECD, Portugal has recently adhered to the Recommendation of the Council concerning Effective Action against Hard Core Cartels,46 through which it has committed to, notably, 'seek ways in which co-operation might be improved', share 'documents and information with foreign competition authorities', gather 'documents and information on behalf of foreign competition authorities' and 'engage in consultations over issues relating to co-operation'.

Additionally, the AdC develops cooperation on a bilateral basis. For instance, in 2019, the AdC and the Spanish National Commission on Markets and Competition (CNMC) met in Madrid at the 8th Bilateral Meeting between Portugal and Spain to coordinate their research and sanctioning activity in the Iberian Peninsula. The AdC also participated in two meetings of the Lusophone Competition Network to strengthen cooperation between competition authorities of Portuguese-speaking countries. Moreover, in November 2019, the AdC signed a protocol with the Moroccan Competition Council, promoting bilateral cooperation and sharing of good practices in matters of competition policy and defence.

In terms of practical developments and coordination in actual cases, the AdC also formally cooperated with the CNMC in case No. PRC 2011/01 (Polyurethane Foam cartel), which was also being investigated in Spain, by carrying out coordinated dawn raids.47

Jurisdictional limitations, affirmative defences and exemptions

i Extraterritoriality

Portuguese competition law is applicable to all activities, be it in the private or public sectors and regardless of the nationality of participants. The Competition Act applies to cartel practices that take place in the Portuguese territory or that have, or may have, effects in Portugal.48

Therefore, in theory, any agreement between undertakings located outside the Portuguese territory may be investigated and sanctioned in Portugal if they may affect competition within the country. However, in practice, there are no records of decisions where cartels that occurred outside Portugal, but with impact in the Portuguese territory, have been investigated by the AdC.

ii Parent company liability

Even though the AdC has tried to extend the liability for competition law infringements to parent companies, similar to that within the EU, there appear to be substantial differences, in practice, between the application of this principle at the EU level and in Portugal.

Indeed, in several cases, the AdC has directly fined subsidiaries that participated in cartels (or other restrictive practices) without charging, or even involving, the parent companies.49 In other cases, the AdC's intention to involve the parent company has been limited by the applicable internal legal provisions.

In this regard, the Lisbon Court of Appeal, in a case of abuse of dominant position, has clearly stated that the mere knowledge by the parent company of any infringement by the subsidiary shall not involve ipso jure the attribution of liability to the parent.50 This is primarily because the imposition of liability on the parent based on the mere knowledge of the subsidiary's infringement could be incompatible with certain constitutional principles of criminal procedure that apply to competition proceedings, given their quasi-criminal nature and the application of very heavy pecuniary sanctions.51

As for the calculation of fines, even if the Competition Act does not specify any geographical reference to be considered in terms of the turnover, from the AdC's practice, and according to the guidelines on the calculation of fines, it seems that the turnover in Portugal is taken into account.52

iii Affirmative defences and exemptions

Article 10 of the Competition Act excludes certain agreements from the scope of the Article 9 prohibition.

For this purpose, these agreements must, cumulatively, (1) 'allow the users of the concerned goods or services an equitable part of the resulting benefit', (2) 'not impose on the undertakings concerned any restrictions which are not indispensable to the attainment of these objectives', and (3) 'not afford such undertakings the possibility of eliminating competition from a substantial part of the market for the goods or services at issue'. Provided that each of these criteria are fulfilled, the undertakings may be exempt from the respective sanction that can occur in the case of vertical agreements. However, it is highly unlikely that a cartel agreement could qualify for such an exemption.

The AdC has also made it clear that the 'state action' defence is not widely available to justify coordination between operators. In fact, according to the AdC, the state must refrain from promoting arrangements between competitors, as addressed in a case concerning meetings promoted by the government of the Azores with several milk producers in which commercial conditions might have been discussed. The AdC closed the case without imposing any sanctions, but recommended that the government of the Azores end the practice and refrain from acting in any way that could potentially facilitate collusive behaviour in the region.

Leniency programmes

i Legal framework

The leniency programme in Portugal, as at the EU level, is a mechanism that enables participants (individuals or legal persons)53 in a cartel to obtain full or partial immunity by collaborating in the AdC's investigation.

Despite not being explicit in the law, this mechanism is understood as applying exclusively to cartel cases and does not apply to the other offences provided for in Article 9 (decisions of associations of undertakings and concerted practices).

However, the AdC admitted a leniency application in a case of exchange of information without suspicion of cartel activity.54 The point is that this limitation to cartels is no more than a direct application of the constitutional principle of proportionality according to which the AdC cannot resort to a mechanism that is not strictly necessary and appropriate (Article 18(2) of the Portuguese Constitution).

The Portuguese leniency regime, provided under Articles 75 to 82 of the Competition Act, lays out a regime that allows the AdC to grant immunity from fines or a reduction of fines in administrative proceedings concerning prohibited practices under Article 9 of the Competition Act.

These rules provide that every individual or legal person that could be sanctioned for participating in a cartel may apply for immunity from, or reduction of, a fine under the Competition Act. The moment when the applicants present themselves to collaborate with the AdC is crucial, as only the first undertaking to denounce the existence of the infringement shall benefit from full exemption from the fine. The subsequent undertakings that do so may only benefit from a reduction of up to 50 per cent.

For this purpose, the Competition Act provides for several levels of reductions, depending on when each application was made, and according to which the first undertaking (after the one eligible for immunity) providing information and evidence that is of significant added value is entitled to a reduction of 30 to 50 per cent, the second may benefit from a reduction of 20 to 30 per cent and the subsequent undertakings from a reduction of up to 20 per cent.

The procedural rules for leniency are laid down in a separate regulation, Regulation (EU) No. 1/2013, and completed with the AdC's Guidelines on Leniency Applications. The leniency application must be submitted by a written request providing, notably:

  1. the object of the application;
  2. the identification of the applicant;
  3. precise and detailed information on the cartel;
  4. identification of, and contact details for, the involved companies; and
  5. an indication of the existence of requests made in other jurisdictions.55

The AdC provides a template for the submission of a summary application for immunity from, or reduction of, fines.

The granting of the exemption or reduction is not automatic and the applicant must:

  1. promptly provide all the information and evidence that the applicant has or may obtain;
  2. respond expeditiously to any request for information that may contribute to determining the facts;
  3. refrain from any act that may hinder the progress of the investigation; and
  4. refrain from disclosing the existence or the contents of the application, or the intention to submit such an application.56

Nevertheless, the Competition Act provides that the application for immunity from, or reduction of, the fine is confidential, along with all the documents and information submitted for the purpose of immunity or reduction.57 However, the AdC shall allow access to the parties concerned to the application for immunity from, or reduction of, the fine, and to the respective documents and information, although copies cannot be made unless authorised by the applicant.

In this respect, the Private Enforcement Law offers some protection to leniency applicants through, namely:

  1. the limitation of its joint liability, being liable only to its own direct or indirect customers or suppliers, and to any other injured parties that cannot obtain full compensation for the damages suffered from the other infringing companies (Article 5(4)); and
  2. the limitation of access to leniency applications as evidence, by preventing the use of declarations made for the purposes of exemption or reduction of a fine as evidence (Article 14).

ii Decision practice

There are several public cases in Portugal that started on the basis of leniency applications by undertakings or individuals, which has become more common in recent years.

Catering Services cartel (2007)

The AdC started its investigation following an individual leniency application submitted under the terms of the previous regime provided for in Law No. 39/2006 of 25 August 2006 by a former director of one of the investigated undertakings. The applicant benefited from immunity from fines. However, the remaining cartel participants and its directors were fined a total of €14,720,283 (although this was later reduced by the Competition Court).58

Commercial Forms cartel (2012)

The AdC sanctioned this cartel involving undertakings operating in the printing and graphics sector. Several undertakings were fined for a price-fixing and market-sharing agreement concerning the application form paper market after an investigation triggered by a leniency application. The fines totalled €1.798 million. In addition, three board members were fined €6,000 each for being aware of the cartel and failing to take action to put an end to it.59

Polyurethane Foam cartel (2013)

This was a cartel in the market for polyurethane foam for comfort products. This case is very important since the AdC's investigation was conducted in parallel with a cartel investigation in the same market by the CNMC. The investigation was triggered by a leniency request by an undertaking that received full immunity (as did its board members), and all the sanctioned undertakings and individuals benefited from substantial fine reductions in view of the settlement procedure. The AdC imposed fines amounting to €993,000 on two undertakings and to €7,000 on board members.60

Pre-Fabricated Modules cartel (2015)

In the area of public procurement, five undertakings were sanctioned for anticompetitive practices in public tenders for the supply and assembly of prefabricated dwellings that would be used to enable the normal course of school activities during the reconstruction of certain schools, under a governmental public works initiative named Parque Escolar. In this case, the undertakings involved have waived their right to appeal against the AdC's decision, to benefit from a 10 per cent reduction of their fines. Therefore, the fines imposed by the AdC to the five undertakings amounted to €831,810.61

Office Consumables cartel (2016)

A fine of €440,000 was imposed for restrictive practices of a horizontal nature (cartel) in the Portuguese market for the production and marketing of envelopes. The leniency applicant benefited from full exemption from the fine.62

Insurance cartel (2019)

The leniency applicant benefited from full exemption of the fine as the first company to come forward under the leniency programme and to present the AdC with sufficient evidence of the cartel. Two other participants benefited from a reduction by means of the settlement procedure.63

Banking case (2019)

The AdC fined 14 banks a total amount of €225 million for alleged concerted practice through the exchange of sensitive commercial information. Although not analysed as a cartel, the proceedings were initiated subsequent to a leniency application from a first applicant, which benefited from full exemption from the fine, and a second applicant, rewarded with a 50 per cent reduction of its fine.64

Telecommunication cartel (2020)

In December 2020, based on a leniency application, the AdC imposed a record fine of €84 million on one of the main telecommunications operator in Portugal for alleged market sharing and price-fixing of mobile and fixed telecommunications services with the leniency applicant, another telecommunications operator, which benefits from full exemption from the fine.65

Telecommunication case (2020) – statement of objections

In July 2020, the AdC issued a second statement of objections in the telecommunications sector to the four main Portuguese telecommunications operators for an alleged cartel to limit competition in online advertising on the Google search engine, also following a leniency application.66

In this context, the AdC made clear that it will continue to promote the leniency policy as an essential instrument for cartel identification, particularly through the imposition of heavy and dissuasive fines in cartel cases, to stress the advantages of such a regime.67


In Portugal, cartel activities are administrative (not criminal) offences sanctioned with fines not exceeding 10 per cent of the offending undertaking's turnover in the year preceding the decision.68 Fines imposed to date in cartel cases have generally amounted to around 5 per cent of the infringing undertaking's turnover.

The members of the board of directors of the infringing undertakings, as well as any individuals responsible for the management or supervision of the areas of activity in which there has been a competition law infringement, are liable to be sanctioned under the Competition Act, unless they are subject to a more serious sanction under a different legal provision. They are liable to this sanction when they know of, or it is their duty to know of, an infringement committed, and they have not adopted appropriate measures to end the infringement immediately. The fine imposed on individuals cannot exceed 10 per cent of the individual's annual income deriving from the exercise of their functions in the undertaking concerned.

As an ancillary sanction under Article 71 of the Competition Act, the AdC may impose a ban of up to two years on the undertaking's right to take part in tendering processes for public works contracts or public service concessions, the leasing or acquisition of movable assets or the acquisition of services or procedures involving the award of licences or authorisations by public entities. The ban may be imposed in cases in which the practice leading to an administrative offence punishable by a fine occurred during or as a result of those processes (i.e., bid rigging). Although this ancillary sanction is doubtful – as it limits the number of bidders in future tenders so could, therefore, be considered anticompetitive in itself – the AdC has applied it, for the first time, in March 2020. In the Train Maintenance cartel case, the AdC imposed, on the two companies that did not use the settlement procedure, an additional sanction of a ban of up to two years on participation in public tenders, limited to the tenders relating to the market for maintenance services for track equipment on the national rail network.69

In addition, the AdC may publish an extract of its decision in the Official Journal of the Portuguese Republic and in a national, regional or local newspaper with a large circulation, according to the relevant geographical market.

Article 29 of the Competition Act establishes that the AdC may also impose behavioural or structural measures to end prohibited practices or their effects. This mechanism has never used by the AdC.

In addition to the leniency programme, during the course of investigation (Article 22 of the Competition Act) or during the prosecution phase (Article 27), the parties can put forward a settlement submission by admitting the facts, acknowledging their responsibility for the infractions and accepting that the facts confessed cannot be subject to judicial review by means of appeal.

Although they are not necessarily linked to leniency applications, these cases also involve a negotiation between the companies and the AdC, a collaboration in the investigation through the gathering of evidence, and usually the recognition of some form of misconduct. In recent years, the AdC has made extensive use of the possibility of closing cases with undertakings through this settlement procedure, even though it is not clear, contrary to that taking place at the EU level, what percentage of fine reduction is attributed to settlement.

For instance, in December 2018,70 April 201971 and June 2019,72 in relation to three participants in the Train Maintenance cartel, the AdC concluded proceedings earlier than anticipated because of the collaboration of the companies that admitted their participation in the cartel and the avoidance of judicial litigation by using settlement procedures.73 As the use of this procedure allows the simplification and acceleration of the process, the company benefited from a reduction in the total fine imposed (the percentage of reduction has not been made public). Regarding the remaining companies, the AdC adopted its final decision in March 202074 having imposed a higher fine (total of €1.8 million) and, as mentioned, a ban of up to two years on participation in public tenders.

'day one' response

Under Articles 18, 19 and 20 of the Competition Act, the AdC has a prerogative to perform and execute a broad set of investigative actions in the context of anticompetitive practices. As such, the AdC can:

  1. interrogate the suspected company and each person connected to it, and request relevant documents and information;
  2. interrogate any person whose statements the AdC might find relevant, as well as requesting documents and information when pertinent;
  3. search, examine and apprehend documents, regardless of their physical or digital nature from the company's headquarters and vehicles, necessary to gather evidence; and
  4. temporarily seal locations that are likely to contain relevant documents, to aid in the collection of evidence.

In addition, the AdC can also conduct raids of private residences provided this is authorised by a judge. Raids and document collection conducted at lawyers' and doctors' offices, and banks' headquarters must be done in the presence of a judge, for the purpose of preserving the professional or banking privilege. Additionally, a raid can only be conducted with a warrant from the competent judicial authority, and it must be conducted within the scope of said warrant.

When investigated by the AdC, any person can be accompanied by a lawyer during the process or at a hearing, to assess the legal standing of a defendant before an inspection commences, or to appeal AdC decisions.

Despite these wide powers of investigation, within the Portuguese framework there is some uncertainty related to the scope of these powers. Mainly, this concerns whether emails should be regarded as documents or as correspondence (the latter enjoys increased protection). Some jurisprudence on the matter states that only unread emails should be regarded as correspondence, and the rest should be considered digital documents; a more recent court decision stated that emails could not be used outside a criminal case. This matter is currently under discussion due to the transposition of the ECN+ Directive, which is, as mentioned, spearheaded by the AdC itself. In this context, the AdC suggested, in its proposal of draft legislation for the transposition already submitted to the government, to include the clear possibility for the AdC to have access to, or be able to collect, all information, data or clarifications on any format, whether physical or digital (namely, documents, files and emails or instant messages), irrespective of the support, condition or location in which they are stored, as long as they are accessible to the undertaking under investigation.75

Nevertheless, the AdC seems to be unfazed by these developments, having in recent years conducted a significantly high number of raids,76 including the seizure of emails based on a typical modus operandi – commonly using very broad search words – which often leads to the seizure of a large amount of information classified as personal, irrelevant or unrelated to the case and, on occasion, even seized in breach of professional secrecy.

Because of the possibility of raids, employees should be trained to comply with them and be advised that a record of all taken documents should be kept. Cooperation with the AdC's investigation is an attenuating circumstance taken into consideration in the setting of fines.

Private enforcement

The Portuguese private enforcement regime was established by the Private Enforcement Law, following the Private Enforcement Directive. The legislator aimed to further ensure that the law would fully protect the right to compensation, by expressly allowing the appeal to a collective action for damages.

This Law marks the adoption of the first specific set of rules in force in Portugal concerning actions for damages resulting from a breach of competition rules. Hitherto, cases of damages resulting from anticompetitive infringements judicially claimed were based on general rules on civil liability.

By means of this innovative regime, a claimant may bring a competition claim before the Competition, Regulation and Supervision Court, as being the exclusive jurisdiction competent for these types of judicial claim. It should be noted, however, that the Court only has jurisdiction to rule on matters relating exclusively to infringements of competition law. This seems to leave room for the involvement of ordinary civil courts in damages actions not exclusively related to breaches of competition law.

Resulting from the Directive (Article 17(2)), the Private Enforcement Law provides for a presumption of damages in cartel cases (Article 9(1)), considering that 'cartels shall be liable for damages caused by their infringements, unless proved otherwise'.

The Law provides that it applies to damages actions, as well as to other requests based on infringements of competition law (e.g., nullity of agreements and contractual clauses, unjust enrichment). Moreover, the new legal framework applies regardless of whether the infringement of competition law, on which the claim for damages is based, has already been recognised by a competition authority or a court.

Up to now, the majority of private enforcement cases in Portugal have concerned abuse of dominant position. In this context, as in the rest of the EU, the Trucks cartel has had a substantial impact on private enforcement litigation in Portugal, as an extensive and increasing number of actions for damages compensation are currently pending.

Current developments

According to publicly available information, the sanctioning of competition law conducted in Portugal has occurred more frequently with regard to restrictive practices within trade and professional associations, including price-fixing, and to bid rigging cartels. More recently, the AdC seems to have increased its focus on the food retail sector, having already publicly confirmed that it is currently pursuing more than 10 investigations and having already issued, three statements of objections and sanctioned with a record overall fine six of the main food retail chains in Portugal, two beverage suppliers, a board member and a director, for alleged price-fixing agreements, assessed as hub-and-spoke arrangements.

The AdC has resorted to the leniency programme with increasing frequency, and individual sanctions have also been imposed more frequently. In addition, the settlement mechanism established in the Competition Act was first used in 2013 and is increasingly being used, proving to be a very useful instrument to investigate and prove cartel cases, as well as for other antitrust infringements.

Within the leniency programme, the AdC is proposing an extension of the possibility of granting immunity from fines or a reduction of fines to associations of undertakings as long as they, themselves, participate in an economic activity and have, themselves, participated in the infringement, and not on behalf of their members. The AdC has proposed that the grant of exemption from fines under the leniency programme should be subject to additional requirements to ensure that the applicant fully cooperates with the AdC throughout each of the stages of the programme. The possibility of including the leniency procedural rules within the Competition Act is also being discussed, as it is now under autonomous regulation.

The next significant development in terms of the legal framework relates to the transposition of the ECN+ Directive, for which a proposal of draft legislation prepared by the AdC was submitted to the Portuguese government on 3 April 2020.77 For instance, it expressly provides that the AdC shall be able to access any technological device, including smartphones, tablets and cloud servers, and it extends the type of elements that may be covered by AdC raids and seizure procedures to include explicitly read and unread emails and instant messaging systems.

The outcome of the appeals in the Insurance cartel and in the alleged infringement in the banking sector – which are expected in the course of 2021 – will be very significant in the interpretation of the related legal concepts.

In conclusion, the modifications to the Competition Act that may result from the transposition of the ECN+ Directive are likely to represent a significant change to Portuguese competition law, since it will give the AdC important new powers, and even more so considering the AdC has been much more pro-active in recent years, particularly in 2019 and, despite the pandemic situation, in 2020, in developing a more aggressive competition enforcement policy in various sectors.

8 Article 2(j) of the Private Enforcement Law refers to the definition of the term 'statement for the purpose of immunity from fines or reduction of fines', as being 'an oral or written communication made voluntarily by or on behalf of an individual or an undertaking to a competition authority, . . . describing the information of which that individual or undertaking has knowledge about a secret cartel'.

9 In certain circumstances, facts constituting a cartel involving public procurement (e.g. bid rigging) may be investigated as a crime of disruption of public tenders (under the jurisdiction of the Public Prosecutor Office), potentially resulting in criminal sanctions.

10 Some scholars even suggest that the fine could amount to 20 per cent when there is more than one infringement. According to Miguel Moura e Silva, in Direito da Concorrência (2018), p. 441, 'The limit of the fine may be higher than that provided by [the Competition Act] in case of multiple infringements (Article 19(2) of the General Regime of Misdemeanours)'. Article 19(2) of the General Regime of Misdemeanours provides that when there is more than one infringement, the maximum fine may be twice the abstract maximum applicable to the most serious offence. This theory has not, to the best of our knowledge, been enforced in practice.

11 When directly involved in the unlawful decision/practice, members of the board of directors, as well as any individuals responsible for the management or supervision of the infringing undertaking may be sanctioned with fines up to 10 per cent of their annual income deriving from the exercise of their functions in the undertaking concerned, during the year when the prohibited practice occurred (see Section V).

12 The nature of this ancillary sanction is quite questionable, as it limits the number of bidders in future tenders and consequently may have the opposite effect by ultimately restricting competition within the concerned tenders/markets (see Section V).

13 Despite the absence of a fixed percentage reduction provided in the Competition Act, the AdC tends to apply the 10 per cent reduction as defined at the European level. See, for example, case PRC/2014/02, 9 July 2015 Section 314 and case PRC/2016/06 (Train Maintenance cartel), where although not explicitly mentioned, references to negotiations with one of the participants seem to indicate a 10 per cent reduction mark, Section 966.

14 Such possibility was mainly applied in cases of vertical agreements and decisions of associations of undertakings. See, for example, case PRC/2018/4, 6 June 2019.

50 Decision of the Lisbon Court of Appeal, case No. 36/16.QYUSTR.L1, 14 July 2017, Associação Nacional de Farmácia.

51 On this topic, the transposition of the Directive ECN+ will probably bring changes. Indeed, the draft of transposition proposes to amend article 73 of the Competition Act providing for joint and several liability in two scenarios: (1) the companies are part of the same economic unit or one company exercises determining influence on another at the time of the infringement; or (2) for the economic successors of the infringing company.

52 Section 19 of the Guidelines provides that for the calculation of the base amount of turnover 'the updated average of the sales and services rendered, directly or indirectly related to the infringement, carried out in Portuguese territory' is taken into account.

53 Articles 76(b) and 79(1) of the Competition Act provide that 'Members of the board of directors or the supervisory board of legal persons and equivalent entities, as well as those responsible for the executive management or supervision of areas of activity where an administrative offence has occurred' may benefit from immunity from fine.

54 This case is currently subject to appeal before the Competition Court. See Press release 17/2019, available at

68 According to general rules subsidiarily applicable to misdemeanours, when there is more than one infringement, the maximum fine may be twice the abstract maximum applicable to the most serious offence, which, in a cartel, would be 20 per cent of the turnover of the offending undertakings (see Miguel Moura e Silva, in Direito da Concorrência (2018), p. 441). However, this theory has not, to our knowledge, been applied to competition infringements in Portugal.
