Zaki-ur-Rehman Lakhvi, one of seven men facing trial over the attacks in the Indian city, was granted bail by a court in Islamabad on Thursday.
Mr Lakhvi remains in custody for now, however, after Pakistani authorities issued a three-month detention order.
The attacks in Mumbai, which left 165 people dead, damaged peace efforts between India and Pakistan.
The decision to grant Mr Lakhvi bail came a day after Pakistan PM Nawaz Sharif vowed to end terrorism in Pakistan.
Mr Sharif’s comments followed the deadliest ever attack by the Taliban in Pakistan in which 141 people, mostly children, were killed at a school in Peshawar.
Correspondents said the decision to allow Mr Lakhvi bail was embarrassing for the Pakistani authorities, who are under pressure to bring suspects in the case to justice
