Imran Khan and his wife on Saturday on charges of unlawful marriage, his lawyer said.
Naeem Panjutha said the court announced the ruling in garrison city of Rawalpini.
Khan, 71, and his wife, Bushra Khan, also known as Bushra Bibi, were sentenced to seven years in February when a court found them guilty of breaking Islamic law by failing to observe the required interval between Bibi's divorce from a previous marriage and her marriage to Khan.
