1. Urgency arises when an event occurs which requires contemporaneous resolution, the absence of which would cause extreme prejudice to the applicant. The applicant must exhibit urgency in the manner in which he has reacted to the event or threat. 2. Self-created urgency, including urgency stemming from deliberate or careless abstention from action until a deadline draws near, is not the type of urgency contemplated by the rules. 3. An applicant must take the court into his confidence and clearly demonstrate the chronology of events showing when the need to act arose and what harm is apprehended. 4. An order that does not provide for a return date and remains in force pending the conclusion of other cases with their own procedures is final in effect, not provisional, and can only be granted where a clear right has been established on a balance of probabilities, not on prima facie proof. 5. For an order to have the effect of interim relief, it must be granted in aid of, and as ancillary to, the main relief which may be available to the applicant on final determination of his or her rights.
