Simultaneous elections are not possible without a legal framework as any extension or curtailment of the term of assemblies will require a constitutional amendment, Chief Election Commissioner O P Rawat said today, a day after the BJP made a fresh push to hold Lok Sabha and assembly polls together.

Pointing at the need for a legal framework, he virtually ruled out holding simultaneous polls any time soon. "If the term of some state assemblies needs to be curtailed or extended, then a constitutional amendment will be required... Logistics arrangements with regard to 100 per cent availability of VVPATs (paper trail machines) will be a constraint," he told reporters to a question on whether simultaneous elections can be held anytime soon.
