If you take a look at the archives, and look at the DG1 and DG2 PIs, you will see they they were done in a speedy manner. A post was posted in the PI thread (then judiciary), and a PI thread would be made within a few hours. That thread would be up for a certain amount of hours (I think 72?), then a guilty/innocence poll was put up. If they were guilty, then a sentencing poll.
