The question asks to identify which type of dispute falls under the Supreme Court’s original jurisdiction as specified in Article 131 of the Constitution of India.

Understanding Supreme Court's Original Jurisdiction (Article 131)

Original jurisdiction refers to the power of a court to hear a case for the first time, as opposed to appellate jurisdiction where the court hears appeals from lower courts. Article 131 of the Constitution of India defines the original jurisdiction of the Supreme Court.

Key Provisions of Article 131

• Article 131 specifically grants the Supreme Court jurisdiction over disputes concerning:
  • Disputes between the Government of India and one or more States.
  • Disputes between the Government of India and any State or States on one side and one or more other States on the other side.
  • Disputes between two or more States.

Analysis of Options

• Option 1: Disputes between States or between a State and the Union - This aligns directly with the text of Article 131 and falls under the Supreme Court's original jurisdiction.
• Option 2: Election petitions against sitting Members of Parliaments - These matters are typically handled by specific tribunals or High Courts, not under Article 131.
• Option 3: Enforcement of fundamental rights of individuals - While the Supreme Court can enforce fundamental rights under its writ jurisdiction (Article 32), which is a form of original jurisdiction, Article 131 pertains specifically to inter-governmental disputes.
• Option 4: Appeals from criminal cases in High Courts - This falls under the Supreme Court's appellate jurisdiction, not its original jurisdiction defined by Article 131.

Conclusion

Based on Article 131 of the Constitution of India, disputes between States or between the Union and one or more States are exclusively under the Supreme Court’s original jurisdiction.
