WESTBROOK – The leader of a campaign to overturn the city’s new gay rights law has presented more than enough signatures to the city clerk’s office to force a referendum.

Paul Volle, director of the Christian Coalition of Maine, had presented 1,539 certified signatures to the office as of Monday. That is 457 more than is needed to force a vote on the issue.

Volle said many residents are opposed to the new law on moral and legal grounds. Others are angry because the council passed the ordinance in July without putting the matter out to a vote, he said. “The momentum is on our side,” he said.

The ordinance prohibits discrimination in housing, employment, credit and access to public accommodations based on a person’s sexual orientation.

Volle, who lives in Westbrook, is a longtime opponent of gay rights laws and helped force a statewide vote several years ago that overturned a similar state law. He also helped overturn a Lewiston ordinance.

The Rev. Susan Gilpin, who proposed the ordinance last winter, said she and her supporters welcome the challenge. She said she is helping organize an educational campaign to familiarize people with the language of the law and the large number of the political and business leaders who support it.
