This actually has nothing to do with filibusters and nothing to do with the situation that Mr. Boshcoff found himself in. It has to do with people bringing forward a notice of motion and then not bringing the motion itself forward. If a motion comes forward and there's a filibuster going on, that doesn't guarantee, with or without this, that it is going to be discussed. This has to do with people presenting a notice of motion and then not being prepared to deal with their motion.
So the suggestion is that if you want to bring a notice of motion forward, the person who made that notice of motion has two meetings to move the motion. Then it's up to the committee to decide when the committee wants to deal with the motion. So it doesn't have anything to do with the situation Mr. Boshcoff found himself in, unless he had chosen not to move that motion, if he left it as a notice of motion and didn't make it into a regular motion last spring.
