Abrill Alosilla et al. v. Peru

This case centers on a violation of the right to judicial protection to the detriment of 233 members of the Union of Lima Water and Sewer Service Functionaries, Professionals, and Technicians. Between 1991 and 1992, the State passed laws which eliminated the salary scale system that was in effect. Although the State's constitution guaranteed that these laws would not be applied retroactively, the State applied the laws retroactively and failed to provide an effective domestic remedy for this constitutional violation. The Court found the State violated the American Convention on Human Rights.
