The Government spokesperson, Minister Sílvia Paneque, at the press conference following the executive council meeting, avoided directly stating whether the executive endorsed this type of infiltration. However, she denied any political interference in the police operation, emphasizing the need for the police to act autonomously.
“"All decisions are made from an operational point of view. It is the police commanders who decide proportionality without any political directive. There must be essential autonomy."
The Mossos d'Esquadra have justified the infiltration as a risk assessment in the context of the teachers' strike, assuring that their actions are always based on current legislation and assigned competencies. The Minister of Interior, Núria Parlon, will appear before the Parliament on May 13, 2026 at 4:30 PM to provide explanations and answer questions from parliamentary groups.
The Government has defended that these police operations must be governed by criteria of opportunity and proportionality. The spokesperson indicated that a review will be necessary to assess whether these criteria were met in this specific case.
The infiltration has generated considerable discomfort and indignation within the educational community. Unions such as USTEC, CGT, and Intersindical have announced legal actions, arguing that the Mossos' operation violated fundamental rights such as freedom of assembly, the right to strike, and trade union freedom. When asked about this issue, Minister Paneque reiterated the importance of guaranteeing the right to strike and ensuring that police action is proportionate and timely.
“"The right to strike must be guaranteed, and security-related actions must be proportionate and timely."
A jurist and professor of philosophy of law has argued that the infiltration of the Mossos into the teachers' assembly violates fundamental rights, raising significant constitutional objections. According to his analysis, at least three rights are potentially affected: trade union freedom, the right to assembly, and the right to ideological and associative privacy.
Regarding trade union freedom, the undercover presence of police could have a "demobilizing effect" on union activity. Concerning the right to assembly, the infiltration raises serious doubts about proportionality, as there is no publicly known judicial investigation or evidence of violent crimes that would justify the action. Finally, regarding the right to ideological and associative privacy, the collection of information about participants could affect the protection of sensitive data, protected by Spanish and European regulations.
Both the lawyer for one of the unions and the jurist recall that the Spanish Constitutional Court and the Spanish Supreme Court establish that infiltration must be highly justified for specific crimes, such as the investigation of criminal organizations, and always when there are clear indications of criminality.
