The case was filed in March 2003 to force the Comisión Nacional de Pensiones Asistenciales (national agency in charge of welfare pensions) to grant a disability pension to Daniela Reyes Aguilera, a Bolivian girl who has a disabling condition preventing her from moving legs and arms, speaking, and eating on her own. Article 1, paragraph "e" of Decree 432/1997, which requires foreign citizens to prove legal residence in Argentina for at least twenty years in order to qualify for disability pensions, was contested as unconstitutional.
