The former President had applied last week to be removed from the Interior Ministry's Exit Control List, which bars him from leaving the country. In his petition, Musharraf said he wants to visit Dubai to meet his ailing 95-year-old mother.
The Sindh High Court in Karachi today put off his petition until November 22 after the federal government's Attorney General failed to attend the hearing.
Since his return for the May elections, several cases have been registered against Musharraf.
His inclusion in the list is the only hurdle to his travelling abroad as he has already been granted bail in four major cases, including one over the 2007 assassination of former Prime Minister Benazir Bhutto.
