This judicial decision overturns the initial dismissal of a complaint filed by various groups and six individuals affected by the police action. The complaint had been lodged against the Mossos d'Esquadra, but a Barcelona investigating court had not admitted it for processing.

According to ACN, the Audiència found "relational indications" pointing to a "disproportionate" use of this resource. Even the Mossos d'Esquadra admitted in a report to the Parliament that pepper spray is a "dangerous instrument." The judicial resolution suggests that the reported injuries could be "a consequence of the police action."

The initial complaint, filed by several entities, was dismissed, but in February, the same entities appealed the decision. Concurrently, they filed an appeal with the Commission for Guaranteeing Access to Public Information to demand that the Department of Interior make public the protocol for using this tool.

The police action involving pepper spray occurred during the general strike on October 15 in solidarity with Palestine. Social entities denounced an "indiscriminate" and "disproportionate" use of pepper spray around Sants station, stating that citizen rights and police protocols were violated.

In February, various social, trade union, and human rights organizations, such as Alerta Solidària, CGT Catalunya, the Coalició Prou Complicitat amb Israel (CPCI), the Confederació Sindical d'Habitatge de Catalunya (COSHAC), the Coordinadora Obrera Sindical, Feministes Anticapitalistes dels Països Catalans, IAC (Intersindical Alternativa de Catalunya), Irídia – Centre per la Defensa dels Drets Humans, La Intersindical, the Plataforma Antirepressiva de Barcelona, and the Sindicat de Llogateres de Catalunya, issued a joint statement. In it, they demanded that the Department of Interior ban pepper spray, calling it a "harmful and non-selective weapon" that violates fundamental rights and coerces peaceful protest.
