The elaboration of laws is fruit of a number of procedures previously established that support the politicians in their task to legislate and control. These procedures are denominated Legislative Process. The norm that orients the legislative process in the Chamber of Deputies is the House Rules.
The origin of the legislative process in the National Congress happens with the introducing of the following propositions: law project, resolution, legislative decree, provisional decree and proposal of amendment to the Constitution.
The parliamentarians have the initiative to the lawmaking process, as well as the President of the Republic, the Supreme Court, the Higher Courts, the Republic's General Attorney and citizens.
All propositions are discussed in the two Houses and pass by various stages of analysis and voting. The analysis of constitutionality, admission and merits are made in the Committees. Those subjects over which the Committees do not have conclusive power are deliberated in the House Floor, highest organ of good part of the decisions of the Chamber of Deputies. Conclusive Power is the discussion and voting of a law project by the Committees, when the jurisdiction of the Floor is dispensed, except for those cases when there is recourse of one tenth of the members of the House.
After the National Congress deliberations, there is still the Executive deliberation, that is, the President of the Republic may sanction (approve) or veto (prohibit) the proposition. In the first case, the project becomes a law. In the case of the veto, the project is sent back to the Congress, that decides for the maintenance or the fall of the veto.
If the project is sanctioned, it goes to a complementary phase in which the President of the Republic has a 48 hours term to promulgate it.
