Legal Challenges to Popular Action in Spain: The Role of HazteOír and Iustitia Europa
The organizations HazteOír and Iustitia Europa are evaluating the possibility of requesting the indictment of the Spanish Socialist Workers’ Party (PSOE) as a legal entity in cases involving alleged corruption. This move, which would target the party as a corporate body rather than just individual members, follows their ongoing involvement as “popular accusers” in several high-profile judicial investigations, including the case involving Begoña Gómez and various probes into government-linked figures.
What is the ‘Popular Action’ in the Spanish Legal System?
Popular action, or acción popular, is a unique feature of the Spanish judicial system that allows citizens and private organizations to act as prosecutors in criminal cases, even if they have not been directly harmed by the alleged crime. This mechanism is enshrined in Article 125 of the Spanish Constitution, which grants the public the right to participate in the administration of justice.

In recent months, organizations like HazteOír and Iustitia Europa have utilized this tool to challenge government actions. During a recent public event in Madrid, representatives from both groups argued that this mechanism is essential for democratic transparency. Nouna Lozano, speaking for HazteOír, stated that popular action serves as a vital check on power, asserting that it is not the government’s place to impose limits on this constitutional right.
Why are these organizations targeting the PSOE as a legal entity?
The potential push to indict the PSOE as a legal entity stems from allegations of illegal financing. The groups are investigating financial irregularities linked to the party’s organizational structure, specifically under former secretaries and other officials. Under Spanish law, Article 31 bis of the Penal Code allows for the criminal liability of legal persons—such as political parties or corporations—when crimes are committed in their name or on their behalf by their representatives.
If a judge accepts such a petition, it would represent a significant escalation in the legal pressure on the ruling party. The strategy mirrors efforts seen in other major corruption cases in Spain, where the focus shifted from individual politicians to the financial accountability of the organizations they lead.
What obstacles do popular accusers face?
Despite their active role, these organizations report significant hurdles in the courtroom. Luis María Pardo, president of Iustitia Europa, has highlighted the financial strain caused by the high bail amounts (fianzas) often required by courts to allow a private entity to join a case as a popular accuser.

Beyond finances, these groups have expressed concern over procedural limitations. Pardo specifically criticized recent judicial decisions, such as those made in the investigation into the former Prime Minister José Luis Rodríguez Zapatero, which restricted access to parts of the case file to prevent leaks. The groups argue that these restrictions often impact the accusing parties more severely than the defense, potentially hindering their ability to build a case.
Summary of Key Challenges
- Financial Barriers: Courts frequently demand substantial deposits, which smaller organizations struggle to provide.
- Procedural Restrictions: Judicial orders meant to protect the integrity of investigations can limit the information available to popular accusers.
- Legislative Uncertainty: Discussions regarding potential reforms to the law governing popular action have raised concerns among civil society groups about the future of their standing in court.
As these legal battles continue, the tension between the government’s desire for procedural efficiency and the civil society’s insistence on the right to participate in the judicial process remains a central point of contention in Spanish politics.
