After the Constitutional Amendment of 2001 the Plenary Session (and not the Chambers) is the only competent to judge the constitutionality of laws. The Plenary Session is, also, competent: a) for cases of general interest that the President introduces directly into it, b) for cases that one of the Chambers submits to it. These cases are submitted by the Chambers to the Plenary Session for two reasons: either because they are cases of general interest or because the applicable legislative provision is judged unconstitutional.
