In a significant ruling that could affect the trial of seven suspects charged with involvement in the Mumbai attacks in Pakistan, a bench of the Lahore High Court on Tuesday ruled that the confessional statement of Ajmal Amir Kasab could not be used against the accused.

The Rawalpindi-based bench of the Lahore High Court gave its order in response to a petition filed by LeT commander Zakiur Rehman Lakhvi and other accused who are being tried by an anti-terrorism court for planning and help execute the 2008 attacks in Mumbai.

However, the High Court bench dismissed the plea by Lakhvi and the other accused for their acquittal.

Lashkar-e-Taiba is accused of carrying out the attack on November 26, 2008 that killed 166 people.

The bench said they could not be acquitted at this stage while their trial was underway in the anti-terrorism court.

Shahbaz Rajput, a lawyer defending some of the accused, said the High Court bench had ruled that the statement made by Kasab to Indian authorities could not be used in a Pakistani court as it violated Article 43 of the Qanun-e-Shahadat Order of 1984 or evidence act.

“This article states that the statement of an accused can be used against the co-accused only if they are all appearing in the same court for the same case,” Mr. Rajput told PTI.

Mr. Rajput said the High Court had ruled that the anti-terrorism court had exceeded its powers by separating the trial of Kasab from that of the seven accused.

“There was no legal basis for this separation of the trial. The High Court said this was in excess of the powers of anti-terrorism court,” he said.

The High Court said the anti-terrorism court should declare Kasab a “proclaimed offender” or fugitive and authorities should submit a charge-sheet against him.

The High Court also said the accused would be free to submit petitions challenging the evidence presented against them at a later stage of their trial in the anti-terrorism court.

Sources said Kasab’s confessional statement formed a crucial part of the case prepared against the accused by the Pakistani prosecution.

Defence lawyers have been demanding that Kasab’s statement should be excluded from the evidence as he had retracted it during proceedings in a court in Mumbai.
