Agreed. Legislation should be clearly within the consitition, beyond any doubt. Back and forth with the constitutional tribunal pushes the boundaries of the constitution, and risks the tribunal conceding. In addition, the tribunal many times can't enforce violations of the spirit of the constitution, only blatant concrete breaches.

And remember, the constitution was an agreement signed by many groups, and every single clause of it represents the result of negotiations and struggles.

Changing the constitution means overriding that consensus.
