Chaudhry Nisar Ali Khan said Musharraf would go on trial under article 6 of the constitution for declaring a state of emergency in 2007 and suspending the constitution.
Khan said the government would send a letter to the supreme court on Monday requesting the start of treason proceedings.
Musharraf would be the first military ruler to be tried for treason in a country that has experienced three military coups in its 66-year history. He could face the death penalty or life in prison if convicted.
