Strategic litigation is a vital tool for civil society organizations (CSOs) across Latin America to influence public policy. In recent years, this approach to legal advocacy has helped develop new precedents and formal mechanisms that enable greater and more effective participation by CSOs in corruption-related cases—both domestically and in those involving transnational crimes.
Citizen Participation in Preventing and Combating Corruption
In contexts of systemic corruption, public trust in government institutions erodes. Over time, this undermines democratic order and the rule of law. Corrupt practices often involve the misappropriation of public funds intended for development and the public good, thereby reallocating resources in ways that interfere with the enjoyment and realization of human rights, particularly for vulnerable populations.
Understanding corruption solely as a crime against the public administration presents a limited view of its impact. This narrow perspective reduces the harm to financial loss, ignoring its direct link to violations of fundamental rights. In contrast, an interpretation aligned with international standards and commitments recognizes society—and each individual within it—as the true victim of corruption-related offenses.
This broader view underscores the essential role of civil society. Through the work of CSOs, not only can corruption risks be reduced, but these organizations can also help ensure that prosecutorial agencies fulfill their duties appropriately. Civil society plays a crucial role in applying social oversight, reducing impunity, and challenging the power dynamics—especially the nexus of political and economic power—that often obstruct effective investigations.
International standards are unequivocal on the value of civil society participation in judicial processes against corruption. Combating corruption is more effective and sustainable when it upholds human rights and centers people in its strategies. The Inter-American Convention Against Corruption (IACAC) affirms this in its preamble, stating that “combating corruption strengthens democratic institutions, prevents economic distortions, inefficiencies in public management, and deterioration of social morality.” Similarly, the United Nations Convention against Corruption (UNCAC) stresses that “the prevention and eradication of corruption is a responsibility of all States and that they must cooperate with each other, with the support and involvement of individuals and groups outside the public sector, such as civil society, non-governmental organizations and community-based organizations.”
Both conventions encourage CSO participation in judicial proceedings investigating corruption. International bodies have also emphasized the importance of States establishing mechanisms that enable CSOs to play an active role in anti-corruption efforts, noting that “the right to monitor the development of anti-corruption processes and to litigate in such cases is a standard grounded in human rights and anti-corruption policy systems.”
Despite this legal framework, opportunities for meaningful CSO involvement in corruption investigations remain limited. The lack of formal mechanisms, excessive bureaucracy, and high associated costs make it practically impossible for many CSOs to engage. This is where strategic litigation becomes indispensable—it opens avenues for citizen participation in anti-corruption processes. The experience of Poder Ciudadano, the Argentine chapter of Transparency International, offers valuable insights for other organizations seeking to initiate strategic litigation and establish precedents that formally recognize CSOs and the “true victims” of corruption in judicial proceedings.
Strategic Litigation in Corruption Cases
Strategic litigation, defined as legal action aimed at producing changes in laws or institutional practices beyond achieving a favorable ruling in a specific case, has gained momentum over the past two decades. It has allowed CSOs to reshape public policies or eliminate practices that undermine community rights. While traditionally associated with serious human rights violations, strategic litigation has recently been applied to high-profile corruption cases that constitute crimes against the state and result in severe human rights violations.
Still, achieving impactful outcomes, such as establishing formal channels for CSO participation in corruption investigations, remains challenging. Despite recognition in international instruments and many national laws, specific mechanisms and procedures that allow CSOs to engage in judicial processes are lacking.
Importantly, participation should not be limited to CSOs acting as formal complainants. While this legal standing is essential—enabling CSOs to submit evidence, suggest lines of inquiry, and file motions or appeals—it can be prohibitively risky and expensive. When corruption investigations involve powerful political or economic actors, CSOs often face threats to their reputations, staff safety, and institutional integrity. These risks are compounded by the technical complexity, cost of evidence collection, and legal sophistication required in such cases.
As a result, CSOs in the region have been developing new forms of engagement through strategic litigation. These efforts aim to minimize risks while supporting prosecutors and contributing to truth-finding processes. Organizations within the Transparency International network—such as Poder Ciudadano in Argentina—have advanced creative strategies that have produced promising results and set important precedents for CSO involvement in corruption investigations.
CSO Participation in Investigations
As part of its advocacy strategy, Poder Ciudadano has engaged the judiciary to create legal precedents and, in some cases, advocate for regulatory reforms that enable genuine CSO participation in corruption investigations. Tools employed include formal complaints, the adaptation of legal mechanisms like amicus curiae briefs in criminal proceedings, and the development of new roles such as “external collaborator.” Over the past decade, these efforts have generated replicable models across jurisdictions.
The Amicus Curiae as an Advocacy Tool
In one Argentine case, Poder Ciudadano submitted an amicus curiae brief to the World Bank’s Ethics Tribunal after two employees were suspended for allegedly leaking information to a journalist about a public official’s travel expenses linked to a corruption case. The Bank argued the employees had disclosed “non-public” institutional information. In response, Poder Ciudadano provided standards and insights on how whistleblowers acting in good faith to expose corruption should be protected.
The Bank ultimately reinstated the employees and revised its policies on whistleblowers and good-faith informants in corruption cases. This marked the first time a civil society organization’s opinion influenced World Bank policy reforms in this area.
Legal Complaint as a Form of Participation
Following a complaint involving alleged corruption in Argentina’s Ministry of Social Development and the National Technological University (UTN), Poder Ciudadano developed a multi-level strategy. The case involved suspected misappropriation of funds from the “Argentina Trabaja” social program, with fake work assignments and fraudulent scholarship payments. A journalistic investigation revealed that listed “workers” were, in fact, students who had never participated in the program.
Poder Ciudadano represented over 40 individuals and itself as a complainant. The judge accepted both, recognizing the organization’s alignment with public interest goals. The defense appealed, but the appellate court upheld the inclusion, stating:
“[W]hen a crime is committed against public administration, even if not directly affecting the legal interests of a private party, it indirectly violates other rights—such as health, education, justice, and housing. Supporting the rule of law—clearly one of Poder Ciudadano’s goals, necessarily includes the defense of these fundamental rights.”
This case was a landmark in Argentina, marking the first time a CSO was formally admitted in a corruption case. It paved the way for regulatory changes allowing CSOs to participate not only in human rights cases but also in corruption-related criminal proceedings.
Creating the Role of “External Collaborator”
Since 2022, Poder Ciudadano, working with Transparencia Venezuela, has sought to assist the Argentine judiciary in cases involving corrupt practices in Argentina–Venezuela trade relations. The aim was to collect and present evidence that could move stalled investigations forward.
In an early case, Poder Ciudadano attempted to submit documents as an amicus curiae. Faced with bureaucratic hurdles, they instead presented the materials under the principle of free evidentiary submission. Although the judge formally rejected the amicus brief, he accepted the information and recognized Poder Ciudadano as an “external collaborator.” He invited continued cooperation and stated that “Fundación Poder Ciudadano may submit any relevant opinions, supported by useful and pertinent evidence. Such cooperation is not limited to the submitting entity and may be extended to any person or institution with relevant knowledge”. The judge also noted that the local and Venezuelan chapters of Transparency International could assist with securing official responses from Venezuelan authorities, potentially alongside the prosecutor, if deemed appropriate.
Following this precedent, similar interventions were made in other cases, supplying critical information that Argentine authorities otherwise could not have obtained. These contributions enabled prosecutors to continue investigations and pursue new lines of inquiry against individuals accused of embezzling public funds.
In Summary: Never Stop Trying
CSO participation in corruption investigations is neither simple nor confined to established legal tools. Strategic litigation is a powerful resource for creating new roles and practices that enhance civil society’s engagement in anti-corruption efforts, whether as collaborators, active participants, or informed observers.
Whatever approach each organization chooses, the goal must remain clear: to strengthen participation and oversight mechanisms, not only to prevent corruption but also to recover misappropriated public funds. Doing so is essential to protecting democratic institutions and ensuring the full realization of human rights for all.
