Wait a minute. This should have been heard by the SC two years ago, so why now?
To get normies gradually accustomed to the idea that Congress has been dismissed for malfeasance. First it will be announced that 388 members have been dismissed, then when that sinks in, the news of all Congress being arrested will come out. You don't want to shock everyone all at once. Its a brilliant strategy that will soften the blow and minimize protests and violence.
