Code of Civil Procedure Article 248

Except for a claim which may not be adjudicated in the same proceeding, multiple claims against the same defendant may be asserted concurrently by initiating the action in any court which has jurisdiction over one of the claims insofar as it does not intrude on another court's exclusive jurisdiction.
中文原文 民事訴訟法第248條
對於同一被告之數宗訴訟,除定有專屬管轄者外,得向就其中一訴訟有管轄權之法院合併提起之。
但不得行同種訴訟程序者,不在此限。
