§ 1108.Writ Returnable and Heard In Discretion of Court

This is the source of the chapter title's promise that these writs "may issue and be heard at chambers." Section 1108 lets the Supreme Court, a Court of Appeal, or a superior court decide, at its own discretion, that a writ of review, mandate, or prohibition may be made returnable and heard at any time.

Without this flexibility, an extraordinary writ meant to provide urgent relief could be stuck waiting for the court's regular calendar. Letting the issuing court set its own schedule keeps these writs useful for the situations that call for them -- jurisdictional excess that often can't wait.
