The Short Version
The core description is correct: Georgia’s Constitution uses a dual-track amendment procedure, with immediate effect for revisions backed by a three-quarters supermajority and delayed effect for those backed only by a two-thirds supermajority until the next Parliament confirms them. The main inaccuracies are legal wording. The Constitution refers to presidential promulgation, not merely signature, and the next Parliament’s confirmation must itself reach a two-thirds supermajority.
