BROOMFIELD, Colo. - Broomfield officials say a box discovered after a bitterly contested election on a fracking ban included ballots that had been returned as undeliverable or marked as spoiled.
The Broomfield Enterprise reports (http://tinyurl.com/laspmcu ) the box was opened Friday.
Election judges present when the box was opened say some of the ballots had been returned because they had been mailed to people who had died or moved out of state.
It wasn't immediately clear if the envelopes would be opened for closer inspection.
A recount of the November election showed the ban passed by 20 votes out of more than 20,000 cast.
Opponents of the fracking ban have challenged the results, and the Colorado Secretary of State's Office issued a critical report on how the vote was conducted.
