A petition has reportedly been filed in the Islamabad High Court, calling for the suspension of the Gilgit-Baltistan polls scheduled for 8 June.
India had reacted sharply to Pakistan's decision to hold polls in the disputed region, saying that it was an attempt of "forcible and illegal occupation".
The petition to suspend the Gilgit-Baltistan polls was filed by All Pakistan Muslim League (APML) chief coordinator Ahmed Raza Khan Kasuri on Thursday, The Express Tribune reported.
"Ministry of Kashmir Affairs is ruling the two million people of Gilgit-Baltistan in a colonial way by violating the fundamental rights," the petition said, adding that the Pakistani government had no constitutional and legal authority to issue executive orders to issue notification for holding elections in the region.
Following news of the Gilgit-Baltistan polls, India has said that "the entire State of Jammu & Kashmir which includes the regions of Gilgit and Baltistan is an integral part of India".
"We are concerned at continued efforts by Pakistan to deny people in Gilgit-Baltistan, part of Indian state of J&K, their political rights," Ministry of External Affairs spokesperson Vikas Swarup had said in an official statement.
"The election in Gilgit and Baltistan on June 8 under the so called "Gilgit Baltistan Empowerment and Self Government Order" is an attempt by Pakistan to camouflage its forcible and illegal occupation of the regions," he added.
