Silva v. Organization of American States

The dispute originated in labour proceedings brought by an individual against the Organization of American States (OAS). After obtaining a favorable judgment before a Labour Court, the claimant sought enforcement of the amounts awarded.

On appeal, the Regional Labour Court dismissed the enforcement proceedings, accepting the OAS’s invocation of immunity from execution and holding that both Brazilian law and the 1988 Agreement governing the privileges and immunities of the OAS in Brazil do not allow the seizure of assets belonging to international organizations.

The claimant then appealed to the Superior Labour Court, which partially granted the appeal. The Court reasoned that the 1988 Agreement restricts only coercive enforcement measures directed at the organization’s property. However, according to the Court, this immunity does not prevent the release of the mandatory appeal deposit voluntarily provided by the OAS during the course of the proceedings. Since this deposit had already left the patrimony of the organization and was held in a court-supervised account, the release of these funds to the claimant did not amount to a prohibited attachment. The Court, therefore, authorized the release of the deposit while maintaining the OAS’s immunity from other enforcement acts.

The claimant subsequently sought to challenge the remaining enforcement limitations by filing a constitutional appeal before the Supreme Federal Court, alleging violations of constitutional guarantees such as access to justice and the protection of vested rights. The constitutional appeal was rejected at the admissibility stage on the ground that the alleged violations concerned issues of ordinary statutory interpretation rather than direct constitutional matters. This rejection gave rise to an internal appeal.

The Supreme Federal Court unanimously dismissed the internal appeal. It held that no constitutional question capable of supporting a constitutional appeal had been directly addressed by the lower courts and reiterated the established position of Brazilian jurisprudence: while immunity from jurisdiction for international organizations is relative at the merits stage, immunity from execution remains absolute except in exceptional circumstances, none of which were present in this case.
