Pakistan's Supreme Court today summoned former president Pervez Musharraf to defend himself against charges of imposing a state of emergency in 2007.
The bench, headed by Chief Justice Iftikhar Muhammed Chaudhry, asked him to appear in person or be represented in court next Wednesday.
The case challenging Mr Musharraf's imposition of military rule and the axing of judges, including Mr Chaudhry, could lay the grounds for future action - even a trial - against the former ruler.
Attorney general Sardar Latif Khosa has been directed by the court to present the details of payments made to lawyers for defending Mr Musharraf, who is currently staying in London with his family.
If he or his lawyer decide not to appear for the session, the court could reportedly initiate proceedings against him.
The former army chief took over the country in a military coup in 1999 and in 2007 dismissed the Supreme Court chief justice Mr Chaudhry. The move triggered mass protests by lawyers.
Mr Chaudhry was reinstated but the former president declared a state of emergency and dismissed the judge along with 60 others.
Six weeks later, he lifted emergency rule, stepped down as army chief and allowed parliamentary elections to take place in February last year.
He was forced to resign the presidency after his political opposition came to power. Since then, there have been discussions over whether he could have to answer in court for these actions and court petitions were finally filed over the matter.
