1. Punjab Sacrilege Law: Constitutional and Federal Challenges

Why in News?

Punjab’s stringent 2026 law dealing with sacrilege has raised important constitutional questions relating to equality, proportionality, secularism, criminal punishment and Centre-State legislative competence. The law is under legal scrutiny over whether a State can prescribe stringent punishment for offences that substantially overlap with provisions of the Bharatiya Nyaya Sanhita.

UPSC/PCS Importance

This is one of the strongest Polity topics for UPSC and especially Punjab PCS because it connects Fundamental Rights, Article 21, proportionality of punishment, Concurrent List, Article 254, Presidential assent and the constitutional principle of secularism.

Prelims Facts

• Criminal Law is included in the Concurrent List.
• Both Parliament and State Legislatures can make laws on subjects in the Concurrent List.
• Article 254 deals with inconsistency or repugnancy between Union and State laws.
• Under Article 254(2), a State law on a Concurrent List subject may prevail within that State if it receives Presidential assent.
• Article 21 protects life and personal liberty and requires fair, just and reasonable procedure.
• Maneka Gandhi v. Union of India expanded the interpretation of Article 21.
• Mithu v. State of Punjab is important in the constitutional debate surrounding mandatory punishment.
• Secularism forms part of the Basic Structure of the Constitution.

Mains Perspective

GS-II: Constitution, Fundamental Rights, Federalism and Centre-State Relations

3. RBI MPC Signals Possible Recalibration of Repo Rate

Why in News?

Minutes of the Reserve Bank of India’s Monetary Policy Committee meeting indicate that hardening inflation could create a case for recalibrating the policy rate. The policy repo rate has remained at 5.25% since February 2026.
