U.S. President George W. Bush, who values Musharraf as an ally in his battle against al Qaeda and the Taliban, urged Pakistan's president to lift the state of emergency, hold elections and quit his military post.
Police used teargas against stone-throwing lawyers in the eastern city of Lahore, and wielded batons to break up another protest by dozens outside the High Court in Karachi.
It had been unclear whether parliamentary elections would go ahead in January as scheduled.
But Attorney General Malik Abdul Qayyum told Reuters there would be no delay and national and provincial assemblies would be dissolved by Nov. 15 ahead of the vote that is supposed to transform Pakistan into a civilian-led democracy.
There was no indication of when Musharraf would lift emergency rule, which he justified by citing a hostile judiciary and rising militancy. However he said on Monday he planned to give up his military role in nuclear-armed Pakistan.
"I am determined to execute this third stage of transition fully and I'm determined to remove my uniform once we correct these pillars in judiciary and the executive and the parliament," he said on state-run Pakistan Television.
Musharraf, who seized power in 1999 and had been waiting for the Supreme Court to decide if his re-election as president while still army chief was valid, had to dismiss rumors sweeping the country that he had been put under house arrest.
"We Want A Free Election"
Since Pakistan was formed in 1947 by the partition of India after British colonial rule, it has reeled from one crisis to another and spent half its 60 years ruled by generals.
Security has deteriorated since July, when commandos stormed Islamabad's Red Mosque to crush an armed Islamist movement. Since then nearly 800 people have been killed in militant-linked violence, half of them by suicide attacks.
The United States has put future aid to Pakistan under review, having provided $10 billion in the past five years, and postponed defence talks with Pakistan due this week.
