Accrued jurisdiction within the context of the Australian legal system is the power held over state matters by federal courts. Accrued jurisdiction will occur when there are several cases brought to the Federal Court of Australia (FCA) where there are competing jurisdictions between them. In essence the state vests judicial authority in the federal court providing that a number of requirements are met. A claim that is based on a state law for example can be heard in a federal court depending on:
The above test is applied by the court and a decision reached as to whether the court has accrued jurisdiction. A convenient example of this process is outlined in the case "Re Wakim; Ex parte McNally" (1999) HCA where there is a conflict between state and federal jurisdictions. In this particular case it was held that accrued jurisdiction did exist but had it not the FCA would have been acting unconstitutionally had it proceeded hearing the case.
