He claimed in the court that his client was falsely implicated and arrested in connection with a vague FIR on October 6, 2011.
The special NIA court had framed charges against Malik for various offences including that of waging war against India.
The blast had left 15 people dead.
The court had framed charges under sections 121 (waging war against country), 121-A (conspiring to commit certain offences against the state), 122 (collecting arms with intention of waging war against government) and 123 (concealing with intent to felicitate a design to wage war) of the IPC against Malik.
Earlier, the trial court had declined NIA's plea to prosecute Malik under stringent charge of waging war against India which entails maximum punishment of death penalty, but the Delhi High Court had ruled otherwise.
