Ballotting began at 7 a.m. Monday for the 40-member Mizoram legislative assembly, an official said.
Over 6.8 lakh voters are eligible to vote in the exercise to elect 40 members from among 142 candidates. Counting will be held Dec 9.
A newly-designed device, the Voter-Verified Paper Audit Trail (VVPAT) system, is being used in 10 constituencies to help voters confirm that their votes were cast in favour of the candidate and party they opted for.
In the outgoing house, the Congress has 32 seats while the Mizo National Front has three members.
