As per case facts, Mukhtiar Ahmed Ansari was convicted under TADA and the Arms Act for possessing firearms and ammunition. This charge stemmed from an incident linked to a kidnapping ... for ransom case, in which the appellant was previously acquitted by a competent court. The appellant contended that the TADA proceedings were vitiated because the mandatory prior approval from the District Superintendent of Police, as required by Section 20A(1) of TADA, was not obtained. He also argued that the Designated Court erred by re-evaluating evidence from the kidnapping case in which he was already acquitted. The question arose whether the lack of proper prior approval for initiating TADA proceedings rendered the conviction invalid, and if the acquittal in the related kidnapping case should prevent the current conviction based on the same underlying facts. Finally, the Supreme Court held that the prior approval as required under TADA was indeed not obtained, vitiating the entire proceedings under TADA. The Court also found that the Designated Court improperly re-evaluated the facts of the kidnapping case where the appellant had been acquitted. Consequently, the conviction under TADA and the Arms Act was set aside, and the appellant was acquitted, with his bail bond discharged and any fine paid to be refunded.
