The judges of the Court of Quebec preside over each step in the judicial process, from first appearance to imposition of the sentence, as the case may be. They are also very regularly called on to rule on applications for judicial authorization in the course of investigations (e.g., search warrants). The judges share this part of their jurisdiction with the presiding justices of the peace. To ensure the responsibility is properly assumed, presiding justices are available at all times, every day of the year, to analyze such applications.
