A citizen’s initiative to ban transgender athletes from competing on girls’ sports teams is in Maine is the target of a lawsuit.

The suit filed on Friday claims that the citizen’s initiative isn’t valid because of issues with the signatures that were collected, including duplicate signatures and signatures from non-Maine voters.

It also claims that some petitioners didn’t give people an opportunity to read the ballot initiative summary before signing, which would violate state law.

The suit was filed by Maine residents Jane Gilbert, Mark Sayre and Kaitlin Webber in Cumberland County Superior Court.

Earlier this month, Maine Secretary of State Shenna Bellows said the petition effort was valid.

The suit is asking the court to overturn Bellows’ decision or send it back to her for reconsideration.
