Pakistan's top court has ordered former military ruler General Pervez Musharraf to appear before judges in connection with allegations that he committed treason while in power.
The Supreme Court ordered a notice to be sent for him to appear in court on Tuesday.
The judges were responding to several petitions filed alleging that Musharraf committed treason by suspending the constitution and sacking senior judges, including the Supreme Court's chief justice, while in office.
He seized power in a military coup in 1999 but was forced to step down almost a decade later under threat of impeachment by Pakistan's main political parties.
He left Pakistan in 2008 and spent over four years in self-imposed exile before returning last month.
The former president has experienced a bumpy ride since his return. He was only met by a couple of thousand people at the airport in the southern city of Karachi when his flight touched down from Dubai, a sign of how little support many analysts say he enjoys in Pakistan.
The Taliban have threatened to kill him, and he faces a series of legal charges, including some related to the 2007 assassination of former prime minister Benazir Bhutto.
However, he registered a victory on Sunday when he was given approval to run for parliament from a remote district in northern Pakistan.
But judges rejected his nomination in several other districts, and lawyers have said they plan to challenge his right to run.
Pakistan's political system allows a candidate to run for several seats simultaneously.
