During an in-chamber hearing, District Judge I S Mehta framed additional charges under sections 121 (waging war against country), 121A (conspiring to commit certain offences against the State), 122 (collecting arms with intention of waging war against Govt) and 123 (concealing with intent to felicitate a design to wage war) of IPC against Malik, sources said.
Subsequent to framing of the charges, Malik pleaded not guilty and claimed trial after which the judge fixed the matter for April 1 for recording of evidence in the case.
Dev was arrested by National Investigation Agency (NIA) for his alleged role in the case but had later turned approver and was granted pardon by the judge.
The trial court had earlier declined the plea of NIA to prosecute Malik under the stringent charge of waging war against India which entails maximum punishment of death penalty, but the high court had ruled otherwise.
The Delhi High Court had on December 3 last year ordered the trial court to frame charges of waging war against the country against Malik, who is currently in jail.
