First the plaintiff (that's us) presents their arguments.
Then the defendants respond. (so far the only defendants I've seen respond are the FEC.....Obama et al didn't chose to respond earlier, and I'm wondering what's up. There is one point that if the defendant doesn't respond then the court assumes that they are in agreement with the plaintiffs.
Then the plaintiff respond to the defendants response.
Then the court decides.
Right now they are doing this with paper before the case is presented in oral argument. The purpose of doing this on paper is to determine if the case qualifies to actually go before the court.
If the court decides all the criteria is met and there is no decision based on the paper work, then the sequence will be repeated orally using the same game plan.
Thank you, hooisermama. If I can understand it, anyone can! ;-)
