Opposition (15) The Chamber of Deputies of Chaco Province (Spanish: Cámara de Diputados de la Provincia del Chaco), also widely known as the Legislative Power (Poder Legislativo), is the unicameral legislative body of Chaco Province, in Argentina.

It comprises 32 legislators elected in a single multi-member province-wide district through proportional representation.

The legislature operated until September 1955, when a coup d'état intervened all democratic institutions in the country and banned Peronism, changing the province's name back to Chaco.

[3] A second constitutional assembly was called upon by the new regime in 1957, with no participation from the Justicialist Party.

[1] The Chamber of Deputies presently has five permanent commissions: constitutional affairs, general legislation, justice and security, budgets and finances, public works and services, and labour legislation, pensions and social security.
