Final answer:
Permissible permanent multijurisdictional practice is allowed in cases such as interstate matters, diversity of citizenship claims, and where the Supreme Court has original jurisdiction. The judiciary hears both civil and criminal cases, with many federal criminal cases being tried in state courts. Certain religiously inspired laws that affect business operations on Sundays may also be permitted.
Step-by-step explanation:
Permissible permanent multijurisdictional practice is allowed in cases where the judicial system must hear matters that may cross territorial boundaries or involve parties from multiple jurisdictions.
This includes situations where cases involve "interstate" matters, cases of "diversity of citizenship" involving parties from different states or a U.S. citizen and a citizen of another nation with at least a $75,000 claim.
Additionally, such practice extends to cases where the United States Supreme Court exercises original jurisdiction, particularly in matters affecting Ambassadors, Public Ministers, and Consuls, or where a state is a party.
Certain religious practices in law might be seen as permissible if they pass the constitutional muster, such as laws inspired by religious motivations but generally enforceable like blue laws.
The judicial power, as stipulated by the U.S. Constitution, shall not extend to cases against a state commenced by citizens of another state or by foreign citizens or subjects, a principle reinforced by the 11th Amendment. Moreover, the judicial power covers all cases arising under the Constitution, laws of the United States, treaties, cases involving maritime jurisdiction, and when the United States itself is a party.
The federal judiciary is authorized to hear both civil and criminal matters, though it's notable that many federal criminal cases are tried within state courts too.
