"It's an excellent case for appeal," Katpar told reporters after filing a six-page appeal at the provincial Sindh High Court in Karachi. "I am 100 percent sure about my success, I am very confident."

An Anti-Terrorist Court in Hyderabad sentenced Sheikh Omar to death and jailed three accomplices for life on Monday on charges of conspiracy, kidnap and the murder of Wall Street Journal reporter Pearl.

In the appeal, Katpar listed 10 grounds for the conviction to be overturned, although none made any reference to particular evidence presented by the prosecution, instead arguing in general terms that the conviction had not been valid.

"The prosecution evidence has failed to establish the commission of any offence," the appeal document said. "Hence, the conviction as well as the sentence are liable to be set aside, being totally contrary to law and facts."

Defense lawyers for the three co-accused, Sheikh Adil, Fahad Naseem and Salman Saqib, have already filed an appeal at the Sindh High Court, while prosecution lawyers have also appealed, asking for the three men to be sentenced to death.

On Tuesday, Pakistani police said they had received a threat to kill officials if they carry out the death sentence against Omar, and said they had tightened security for the judge in the case as well as the jail superintendent as a result.

The original trial was carried out inside the main jail in Hyderabad, with reporters barred from attending. The High Court in Karachi has not yet set a date for the appeal hearings.

Execution in Pakistan is carried out by hanging, but usually only after an exhaustive appeals process. A life sentence generally means up to 25 years in jail.

Pearl, 38, was researching a story on Islamic fundamentalism when he was kidnapped in Karachi on January 23.
