Islamabad: Pakistan’s anti-terrorism court judge Rana Nisar Ahmed, who is conducting the trial of LeT's Zakiur Rehman Lakhvi and six other suspects in the Mumbai attack case, on Saturday said that that he would give his ruling on April 30.

The judge said that he would give his ruling next week on an application challenging the contention of the defence that Ajmal Kasab and Fahim Ansari cannot be re-tried in Pakistan.

Pakistani prosecutors had filed the application during the last hearing of the Mumbai attacks case on April 16.

"The prosecution and defence lawyers presented their arguments on the matter today. The judge said he would rule on the maintainability of the application at the next hearing," Shahbaz Rajput, one of the defence lawyers said.

The prosecution's application contended that defence lawyers could not present an argument regarding Kasab and Ansari as they did not represent the two men, sources said.

The defence lawyers recently filed an application seeking the start of trial proceedings as soon as possible and recording of evidence against the accused.

The application was filed under Section 403 of the Code of Criminal Procedure and Article 13 of the Constitution, which state that no person can be prosecuted or punished for the same offence more than once.

Kasab was convicted and sentenced to death by an Indian court. The same court acquitted Ansari, but he continues to be in custody in connection with other cases.

The seven Pakistani suspects, including Lakhvi, have been charged with planning, facilitating and financing the attacks that killed 166 people.
