The petition, filed through senior lawyer Faisal Siddiqi, argues that Niazi was never produced before a civilian court after his arrest in connection with the May 9 cases.

Instead, Sarwar Road Police allegedly handed him over to military authorities without lawful authorisation.

Niazi, a PTI activist, has asked the court to strike down the notification dated August 17, 2023, issued by a commanding officer that placed him in military custody.

The plea also seeks to nullify all proceedings conducted by the military court, including the initiation of a court martial.

The PTI leader has requested the LHC to order his release from jail or direct authorities to present him before an anti-terrorism court.
