I'm not sure how this all began. I assume it was not a cabinet decision to suspend the bill's immediate application. I assume it was something that was recommended to them or dealt with by public servants, who said, “We don't want to do this right away. We can delay this for a while.” I just don't think they thought about the legal implications of it. I think they thought they had done it before with government bills. Often a bill will have words in it that will allow them to do such a thing.
This was passed and became law. I think it should have been automatic. That's the impression I have, but I haven't followed this closely or anything. I'm delighted they've changed their position and are now going to allow it to go into effect immediately, which is what I think you have to do with an act of Parliament.
