M. BALA KRISHNA REDDY vs DIRECTOR, CBI, NEW DELHI

The Supreme Court held that the Central Bureau of Investigation (CBI) lacked jurisdiction to initiate proceedings against the appellant under the Delhi Special Police Establishment Act, 1946, as the alleged offences occurred in Madhya Pradesh without the necessary consent from the State Government. The Court emphasized that such consent is a mandatory prerequisite for CBI's authority to act, as stipulated under Article 166 of the Constitution. Consequently, the appeal was allowed, and the proceedings initiated by the CBI were declared invalid.
