The new date for hearing has been fixed for July 30.
With lawyers for both sides ready and waiting, the court clerk announced that the case would have to be postponed because of the Federal Court's tight schedule.
The court today was set to hear the appeal against the dismissal of the case last year by the High Court.
Ramkarpal Singh, counsel for Anwar, said that if successful the case could be thrown back to the High Court or in extraordinary circumstances the Federal Court could hear the case.
If the appeal is unsuccessful it will likely be the end of the road for the case as the Federal Court is the last court available for appeal.
Anwar is suing former Prime Minister Tun Dr Mahathir Mohamad and the government for wrongfully sacking him as the finance and deputy prime minister in 1998.
