Essentially, where do you get the time? Do you get it before the writ?
The obvious problem is.... Right now we have our first fixed-date election, and if we get a majority for one of the parties in the next election, I assume we'll stick with that. We sometimes don't know when our election's going to start, so it's hard to say 60 days before we start some process, whereas figuring out when it ends is easy, and in establishing that you have a limited time period to sort out these problems of identity and residence.
