172. In the defence, the defendant may make a cross-application against the plaintiff to assert a claim arising from the same source as the principal application or from a related source. The court remains seized of the cross-application despite discontinuance of the principal application.
A cross-application is made in writing but defended orally, unless the court, on its own initiative, requires that it be defended in writing.
