During the hearing, Zardari's lawyer Amjad Qureshi told the judge that he could not come to court in person due to the threats.
The head of the Pakistan People's Party had appeared in the court here amidst tight security at the last hearing on January 9.

Speaking to media, Naek said one case against Zardari was only an allegation and nothing could be proved.
Zardari is facing five cases that date back to the time when his slain wife, Benazir Bhutto, was the premier. The cases were deferred earlier as he enjoyed immunity during his tenure as President.
The same court had earlier acquitted several of the co-accused due to lack of evidence.
