The past few years have seen exponential growth in the number of arbitrations with the state and state entities, particularly in major infrastructure contracts. This article provides an overview of recent legal developments regarding the use of arbitration as an alternative to litigation in public procurement and public–private partnership contracts. It also addresses Panama’s experience in investment arbitration cases and highlights its participation in UNCITRAL Working Group III.

Panama’s Constitution recognises the power of the state to submit a dispute to arbitration through contractual arbitration agreements. Additionally, since 2004, the Constitution expressly admits the competence-competence principle, according to which arbitral tribunals may determine their own jurisdiction under the arbitration agreement.
Panama’s arbitration system is governed by Law 131 of 2013 (the Arbitration Law). Regarding the matters that may be submitted to arbitration (objective arbitrability), article 4 of the Arbitration Law provides:
When the arbitration is international and one of the parties is a state or a company, organisation or enterprise controlled by a state, that party shall not invoke the prerogatives of its own laws to avoid its obligations arising from the arbitration agreement.
Although Panama’s Arbitration Law is modelled on the UNCITRAL Model Law, this provision is rooted not in the Model Law but in the international principle by which a state shall not invoke provisions of its internal law to justify its failure to perform an international obligation.
Furthermore, article 14 of the Arbitration Law states:
The Panamanian state will submit to international arbitration the disputes arising from treaties or international agreements to which it is a party, and which have been duly ratified, in cases in which arbitration has been agreed as a method of dispute resolution.
. . . . .
The submission to arbitration agreed with the Panamanian state, as well as with the Panama Canal Authority, is valid, regarding the contracts that they enter into. The arbitration agreement shall be effective by itself, in accordance with the provisions of this Law.
Panama’s Arbitration Law provides that the state may submit its contractual disputes to international arbitration. This has been recognised by the Supreme Court on multiple occasions. However, when the seat of the arbitration is Panama, the Public Prosecutor’s Office must be notified in addition to the state entity involved in the dispute. The public prosecutor has the constitutional role of defending the interests of the state.
In Parienti v ATTT, the Supreme Court annulled the award, among other grounds, because the state was not given notice. This case involved a concession contract for public passenger transport services and land transport terminals. However, the arbitration was not based on the contract but on the bilateral investment treaty between France and Panama. Thus, the state, and not only the ATTT should have been notified of the arbitration proceedings. Likewise, in the FEDEBEIS case, the award was annulled by the Supreme Court because the state (the public prosecutor) was not given notice. FEDEBEIS (Panama’s baseball federation) is a non-profit organisation, part of the Panamanian Institute of Sports (PANDEPORTES), and therefore, the public prosecutor should have been notified of the arbitral proceedings.
Two recent laws reaffirm the power of the state to be a party in arbitration proceedings: the Public-Private Partnership (PPP) Law and the Public Procurement Law. These are not, however, the only ways that the state may participate in arbitration. In fact, each of the investor-state dispute settlement (ISDS) proceedings where Panama is or was a party is grounded on an international investment agreement (IIA), and not an investment contract.
Arbitration under the public–private partnership regime
In 2019, the National Assembly passed Law 93 establishing the PPP regime in Panama. Before its enactment, Panama had adopted laws that privatised state-owned entities, and developed infrastructure and public services projects through joint ventures with private capital. The basis for the administrative concession system for the execution of public work of public interest was Law 5 of 1988, applicable to construction, improvement, maintenance and exploration of roads or other works classified as of public interest.
Law 93 of 2019 defines PPPs as a long-term contract between one or more public entities, and a legal person from the private sector, for the ‘design, construction, repair, expansion, financing, exploitation, operation, maintenance, administration or supply of a good or service to the public entity contracting party or the end-users of any public service’ (article 3). As such, PPPs are commonly seen as a way of structuring public infrastructure investments, enabling the government to transfer costs and liabilities to the private sector.
PPP contracts must include a phase of amicable dispute resolution between the contracting parties for disputes of a technical or economic nature during the execution of the PPP contract. If an amicable solution between the parties cannot be reached, disputes may be submitted to a dispute board (technical panel) or directly to arbitration. This is a major change in Panama’s public policy as it expressly allows for arbitration in PPP agreements.
According to article 77 of Law 93 of 2019, the technical panel shall be composed of two attorneys, two engineers and one economist or financial expert. Any of the parties may submit any technical or economic controversy to the technical panel, which will issue a technical recommendation. This recommendation shall be duly reasoned, but it will not bind the parties. A party who disagrees with the decision of the technical panel may submit a claim to arbitration for a final decision.
Parties to the PPP contract may submit to arbitration the controversies or claims due to the interpretation or application of the PPP contract or its execution (article 78). The PPP contracts shall include not only the arbitration clause but also the rules applicable to the arbitration procedure. However, the Law includes three requirements: the applicable law to the process shall be that of Panama; the seat of the arbitration must be Panama; and the language of the proceedings shall be Spanish. The arbitration is subject to Panama’s Arbitration Law, as modified by the PPP Law and the arbitration clause incorporated in the PPP contract.
Pursuant to Executive Decree 840 of 2020 (article 83), the following matters may not be subject to the dispute resolution system set in Law 93 of 2019: non-contractual disputes; resolutions that affect the company holding the PPP contract; and situations where the PPP contract mandates the settlement of disputes by the contracting public entity. However, contractors may seek compensation through the dispute resolution provisions in Law 93 of 2019 if it does not agree with the contracting entity’s decision.
One interesting point covered by Law 93 of 2019 is the participation in the arbitration procedure of secured creditors under the PPP contract, which will be without transfer of possession of the pledged rights and assets. In other words, arbitral tribunals must admit the creditors as independent third parties in the arbitration proceedings. It is expected that these creditors will have independent claims in the arbitration.
Arbitration under the Public Procurement Law
Public procurement is regulated in Panama by Law 22 of 2006, as restated by Law 153 of 2020, which applies to concessions and other agreements not regulated by a specific law and provides guidelines for public procurement agreements and the bidding process (article 1). Bidding processes are monitored by the Public Procurement Directorate.
The 2020 Law restatement, at article 95, expressly provides for arbitration as a way to resolve the controversies that may arise in the execution of a public procurement contract. In this sense, public entities may include an arbitration clause in their contract specifications or their contracts.
Arbitrations arising from public contracting are subject to the rules of Law 131 of 2013, which regulates national and international arbitration in Panama. As for the arbitration clauses under the public–private association contract regime, the seat of the arbitration shall be Panama and the language shall be Spanish. At the time of writing, the government had not yet regulated for arbitration proceedings under the Public Procurement Law. However, one can infer certain rules that may apply in the arbitration involving public entities. For instance, the existence of an administrative contract termination clause, which is required by the Public Procurement Law, shall not constitute a waiver of arbitral jurisdiction.
Furthermore, under article 17 of Law 131 of 2013, the arbitration clause generates substantive and procedural effects. The substantive effect obliges the parties to comply with the arbitration agreement, submit the controversy to arbitration and formalise the constitution of the arbitral tribunal. The procedural effect consists of the declination of jurisdiction by the contracting entity, the administrative authority, the judicial court or the administrative court of public procurement, and the immediate referral of the case to the arbitral tribunal without further processing or assessing the claims.
Another advantage of submitting a public procurement agreement to arbitration under Law 131 of 2013 is that the tribunal’s decision may only be challenged in an annulment proceeding. According to article 66, annulment is the most appropriate recourse to the protection of a constitutional right that might have been threatened or violated in the course of the arbitration or by the award.
- one of the parties to the arbitration agreement was under some incapacity, or the agreement is not valid, under the law to which the parties have subjected it, or in accordance with Panamanian Law;
- one of the parties was not given proper notice of the appointment of an arbitrator or the arbitration proceedings, or was otherwise unable to present its case;
- the award deals with a difference not contemplated by or failing within the terms of the arbitration agreement or contains decisions that go beyond its terms;
- the appointment of the arbitral tribunal or the arbitral procedure was not in accordance with the agreement of the parties or the applicable law;
- the arbitrators have decided on matters not capable of settlement by arbitration; and
- the international award is contrary to international public policy.
The execution of the award will be suspended until the Supreme Court decides on the request for annulment.
Panama’s experience in ISDS under investment treaties
Panama has signed 25 bilateral investment treaties (BITs), of which 19 treaties are in force. Panama is also a party to 13 free trade agreements (FTAs) with investment chapters (11 in force). These IIAs impose international standards and rules on the government regarding the treatment of foreign investments and investors. In addition, all of the BITs and most of the FTAs ratified by Panama allow foreign investors in PPPs and other concession contracts to pursue the state through arbitration.
Further, Panama ratified the ICSID Convention on 8 April 1996, which entered into force on 8 May 1996. The Ministry of Economy and Finances (MEF) represents Panama before the board of governors of the World Bank and is responsible for managing ICSID membership. The MEF manages ISDS through the office in charge of investment arbitrations, which takes part in arbitration proceedings and oversees the procurement of external counsel for each of the ISDS cases.
The first investment case against Panama was registered before ICSID in December 2006. Since then, the number of cases has grown exponentially. To date, Panama has faced 16 cases under the ICSID Convention and three known cases under the UNCITRAL Arbitration Rules. Currently, there are nine pending cases against Panama based on investment treaties (although two are in annulment proceedings). At least half of these cases are construction-related projects. More importantly, a single case may involve several infrastructure contracts.
That is the case with Omega v Republic of Panama, involving eight different construction projects, pertaining to a variety of state infrastructure matters (contracts with the Ministry of Health, the Ministry of the Presidency, the National Institute of Culture, th judiciary, the Municipality of Colon andthe Municipality of Panama), and based on the Panama–United States Trade Promotion Agreement (TPA). Likewise, in IBT v Republic of Panama, the claimants submitted a request for arbitration under the TPA, the treaty between the United States and Panama concerning the treatment and protection of investment, and the Treaty on Promotion and Reciprocal Protection of Investments between Spain and Panama (TBI Panama–Spain), in relation to 13 infrastructure contracts: four hospital projects with the Ministry of Health, a haemodialysis service project with the Social Security Fund of Panama, five contracts with the Ministry of Housing and Land Management of Panama, two projects for the construction of schools with the Ministry of Education, and one project for the construction and equipment of a women rehabilitation’s centre with the Ministry of Government.
Moreover, some of these construction project agreements include an arbitration clause, which could form the basis of parallel proceedings: one based on the construction contract, and the other one based on an IIA. For instance, in Sacyr SA v Panama, Spanish company Sacyr sued under the UNCITRAL Arbitration Rules for the alleged violation of the TBI Panama–Spain, even though arbitrations were pending before the Court of Arbitration of the International Chamber of Commerce filed by Grupo Unidos Por El Canal (GUPC) Consortium against the Panama Canal Authority (ACP) for alleged cost overruns arising from the Panama Canal expansion project. Similarly, in 2020, Webuild (formerly Salini Impregilo SpA), another company of the GUPC Consortium sued Panama, this time under the Investment Promotion and Protection Agreement between Panama and Italy. Like in Sacyr, the subject matter of the arbitration relates to the Panama Canal expansion project.
This case is perhaps the most emblematic example that Panama has had to face, where the investor, despite having triggered the contract forum, sued the host state in parallel proceedings because it considers that the rights guaranteed by the investment protection treaty had been violated. Not only the basis of the claim but also the defendants differ in both arbitrations: Panama and the ACP. This is not an isolated case and may occur in the context of large infrastructure projects involving complex operations that may give rise to multiple disputes throughout the life of the project.
The multiplicity of arbitration procedures as in Sacyr/Webuild/GUPC v Panama/ACP, derived from the alleged breach of a contract and a treaty, causes the potential risk of double recovery. Moreover, the same infrastructure project may imply the existence of a multiplicity of contracts between different parties (contractors and subcontractors), which in turn may give rise to various disputes subject to parallel arbitration proceedings. In this sense, if the parties have not agreed on accumulation or coordination measures between the different, related processes, the risk of parallel proceedings becomes imminent, bringing with it a series of additional costs for the parties.
Panama’s input into UNCITRAL ISDS reform
In 2017, UNCITRAL Working Group III on ISDS reform received the mandate to focus on the reform of procedural aspects of ISDS, with the mission of: ‘(i) identifying and considering concerns regarding ISDS; (ii) considering whether reform was desirable in the light of any identified concerns; and (iii) if so, developing any relevant solutions to be recommended to the Commission’. Possible solutions, as proposed by some states, include the development of soft law instruments, the establishment of an appeal mechanism and the creation of a multilateral investment court.
Panama is currently a member of the Commission and participates in the discussions of Working Group III, through the office in charge of investment arbitrations at the MEF. Panama has made submissions on different topics, including comments on the different versions of the Draft Code of Conduct for Adjudicators in International Investment Disputes (recently approved by the Commission), and the establishment of an Advisory Centre on International Investment Law. However, Panama, like many other countries, has not taken a stance on some of the proposals under discussion, including the options for establishing an appellate mechanism (ie, standing or permanent body versus roster model), or the establishment of a standing multilateral mechanism. Indeed, more discussion is needed to take a position on some of the topics.
In a consultation made to the Attorney General’s Office on the advisability of the United Nations Convention on Transparency in Treaty-based Investor-State Arbitration (the Mauritius Convention on Transparency), it highlighted the importance of Panama’s participation in the Working Group III discussions. Furthermore, the future adoption of the Mauritius Convention on Transparency represents a willingness of the state to improve transparency in ISDS, contributing to the legitimacy of the ISDS system.

 A similar provision was in force in the previous arbitration law (Decree-Law 5 of 1999) in the following terms: ‘The submission to arbitration agreed upon by the State, autonomous entities, semi-autonomous entities, including the Panama Canal Authority, with respect to the contracts that they sign in the present or in the future. Likewise, they may be subject to international arbitration when the capacity of the state and other public persons is established by an international treaty or convention. The arbitration agreement established in this manner will be effective by itself and will not require the approval of the Cabinet Council and the favourable opinion of the Attorney General.’ However, prior to the constitutional reform of 2004, the Supreme Court of Justice declared unconstitutional the phrase ‘The arbitration agreement thus established will be effective by itself and will not require the approval of the Cabinet Council and the favourable opinion of the Attorney General of the Nation’.

 Panama does not have an official model BIT. Most BITs negotiated by the Ministry of Foreign Affairs are old-generation investment treaties concluded in the 1990s. The FTA investment chapters negotiated by the Ministry of Trade and Industries are more modern and follow other model BITs such as the 2012 US Model BIT. Most of the FTA investment chapters include pre-establishment rights of national and most favoured nation treatment for admission and establishment, subject to a series of exceptions.
