13.Pakistan 27th Amendment Military Power Centralisation (Pakistan Constitution)

Indian Express

What & Where

Pakistan’s 27th Constitutional Amendment: fast-tracked change centralising military control and revising top judicial hierarchy.

Creates over-arching Chief of Defence Forces (CDF) and Federal Constitutional Court (FCC) above existing Supreme Court.

Applies across Pakistan, impacting civil–military relations and constitutional interpretation nationwide.

Quick Facts for MCQs

Security Dimension

  • Centralisation: CDF gains operational control of Army, Navy, Air Force, strategic and nuclear assets.
  • Immunity: Five-star officers shielded permanently from prosecution, enhancing military autonomy.
  • Hierarchy: CDF constitutionally outranks PM, President, Parliament in defence matters.

  • Transfers: Executive can relocate High Court judges; dissent triggers forced retirement, diluting independence.

Governance & Power Balance

  • Militarisation: Amendment codifies long-standing de facto dominance of army into de jure supremacy.
  • Civilian erosion: Elected institutions sidelined in defence, strategic and constitutional spheres.
  • Checks & balances: Concentrated powers plus legal immunity weaken accountability mechanisms across state organs.
