558. If the Superior Court or the Court of Québec is seized, pursuant to Book II, of an application that has the same juridical basis or raises the same issues of law as an application that is before the court under this Title, the court may stay the hearing on a party’s request, provided this cannot result in serious prejudice to the other party.
The stay is maintained until the judgment on the other application has become final, although the court may revise its stay decision if warranted by new circumstances.
