Nepal's government wants the repeatedly extended Constituent Assembly to get yet another three months to finish writing the Himalayan nation's constitution, and even members of the ruling parties are crying foul.

The assembly was elected in 2008 and was supposed to finish the job in two years, but its deadline has been pushed back repeatedly. The current deadline expires Sunday.

Law Minister Krishna Sitaula said a proposal to extend the assembly's tenure was registered at the assembly Tuesday night after an emergency meeting of the Cabinet.
