"The federal government will act according to the findings and suggestions of the assembly," Sindhu told The News daily.
"Such a case will be filed in a sessions court in Islamabad," he said.
Pakistan's Supreme Court has ruled that Musharraf's act of imposing emergency was unconstitutional and illegal, raising the possibility of him being tried for treason.
However, under the constitution, only the federal government can initiate such a case.
Sindhu said according to the High Treason (Punishment) Act of 1973 and a subsequent law of 1976, a person designated by the federal government will file the complaint in a sessions court.
