The Supreme Court of Pakistan has given the country's election commission 30 days to register all eligible voters left out of draft electoral lists.
The petition was filed by former Prime Minister Benazir Bhutto and her opposition Pakistan People's Party. It contends that more than 20 million eligible voters had not been enrolled.
At a hearing Friday, the election commission requested 140 days to prepare the revised lists.
The two-member bench rejected the request, saying the time period was too long. The court instead granted the commission 30 days to make the necessary changes.
The decision comes a day after Pakistani President Pervez Musharraf decided against declaring a state of emergency that could have delayed elections for a year.
