Question

Talking Show has said a couple of nights recently that if the KMT can control 2/3 of the seats, they can do anything, including amend the constitution. I was under the impression it required 3/4 of legislators present for a quorum and 3/4 of them voting in favor of something to amend the constitution. And then the amendments to go referendum. Did Talking Show just make a very bad mistake here, or did I miss something?
