ISLAMABAD: The Supreme Court was hearing the case pertaining to a controversial memo sent to former US military chief Admiral Mike Mullen seeking US intervention to avert a possible overthrow of the government by the military, DawnNews reported.

The case was being heard on Monday by a nine-judge bench of the apex court headed by Chief Justice Iftikhar Muhammad Chaudhry.

Earlier in June 2012, the Memo Commission had held that Pakistan’s former ambassador to US Husain Haqqani was the architect of the controversial memo.

During today’s hearing, the chief justice said Haqqani had stated that if he was called to appear in court, he could do so on a four-day notice.

Haqqani's counsel, Asma Jahangir, said that Haqqani's review plea was still pending along with his petition to be granted exemption from court appearances.

Addressing Jahangir, the chief justice said that the bench had respected the counsel's word as she was a senior advocate.

The chief justice moreover remarked that although earlier Haqqani was ready to appear in court on a four-day notice, now he had filed a request of exemption from appearances.
