I didn't misunderstand it, my initial comment above is still correct.
A petitioner shouldn't need more than three days to withdraw a petition, and I'd argue that is excessive, as 24-48 hrs is sufficient, nor should a petition be allowed to be withdrawn the moment a trial has begun. Like so:
This should give enough time, excessively so, without having last minute withdraws.
Though I still think this can result in folks getting wind of a decision not being in their favor and withdrawing so they can re-draft it and make a more compelling case.
The more concerning aspect is going to be folks using petitions to the court as threats, and constantly bringing forward petitions only to withdraw them.
If petitions are forced to be put forward, then that does stop someone re-drafting and re-drafting and holding it over someone's head.
