The idea is simple and powerful: under certain constitutional rules, the Assembleia da República (Parliament) can — by a super-majority (two-thirds) — “confirm” a law or part of a law even if the Constitutional Court declares it unconstitutional. On paper, that gives the legislature a direct way to keep controversial measures alive.
But reality tells a different story: such overrides have been used only very rarely. And even when possible, doing so carries high political and ethical risk.
