The Argentine Constitution of 1853 established as a rule the representative system. The 1994 constitutional reform incorporated as an exception to this rule two institutes of semi-direct or participatory democracy.
The contents of the popular consultation are provided for in the constitutional text and in law 25,432 regarding the variants, matters, procedures and required majorities. The binding popular consultation must be called by Congress - at the initiative of the Chamber of Deputies - so that the electoral body, through mandatory voting, approves or rejects a bill. If you support it with the majority of valid affirmative votes, the project becomes law.
