Datuk Seri Anwar Ibrahim's application for leave for a judicial review to challenge the Pardons Board's dismissal of his petition for a royal pardon over his sodomy conviction will be heard on August 17.

Justice Datuk Asmabi Mohamad fixed the date in chambers when the case was brought for mention before him today.

Anwar's lawyer Shahid Adli Kamarudin told reporters that the judge also granted his client's application for a minor amendment to the judicial review papers.

On June 24, Anwar, his wife Datin Seri Dr Wan Azizah Wan Ismail and daughters Nurul Izzah and Nurul Nuha filed the application to quash the decision of the board on March 16 and to compel it to advise the Yang Di-Pertuan Agong to pardon and release him.

They also sought a mandamus order to compel the board to re-convene a meeting and consider all materials relating to the petition for a royal pardon.

Anwar, 67, in his supporting affidavit claimed that the decision made by the board was in breach of the rules of natural justice and therefore void.

He is serving a five-year jail term at the Sungai Buloh Prison after the Federal Court on Feb 10 upheld his conviction and sentence for sodomising his former aide, Mohd Saiful Bukhari Azlan, in 2008.
