BOSTON -- As the day set by the Supreme Judicial Court to require Massachusetts officials to allow gay couples to marry nears, legal maneuvering surrounding the issue is growing more frantic.

NewsCenter 5's Janet Wu reported that as May 17 approaches, opponents of gay marriage continue to try to find a way to stop the marriages, while proponents are looking to open marriage to out-of-staters.

Linda Hossfeld was planning her son's June wedding when she received an unsolicited telephone call Wednesday night.

"Four judges in our state have acted against the will of God," the caller said.

"It's very difficult to listen to that kind of a message in my own home," said Hossfeld. "When my son said to me that he was gay, my first thought was, 'Oh my God, there will be people who will hate him just because of who he is.'"

The message invited her to a rally at the Statehouse Thursday asking the Legislature to approve a resolution calling for the removal of four Supreme Court justices who have ordered gay marriages legal beginning next month.

"The train of judicial activism that changes the laws without the people getting involved has to stop here," said Brian Camenker of the Article 8 Alliance.

But the legislator who filed the resolution admitted that even if it's approved, it won't be legally binding. However, some point out, it could embarrass Gov. Mitt Romney.

"(Romney's) made his commitment that he's against gay marriage. If he denies this, he is the one who will be promoting gay marriage on May 17," said Rep. Emile Goguen.

Meanwhile, three legislators supporting gay marriage filed a bill Thursday afternoon to allow gay couples from out of state to marry in Massachusetts. Current law, originally designed to stop out-of-state interracial couples from marrying in the Bay State, has rarely been invoked.

"When they give addresses to the clerks, they're not required to give proof of those addresses, and so it is not a part of the law that we are applying today, and it should not be a part of the law that we are applying solely to same-sex couples," said Rep. Robert Spellane.

"A bill that was used against interracial couples is now going to be used against same-sex couples. That speaks volumes about what is really going on here," said Arline Isaacson, of the Gay and Lesbian Political Caucus.

Wu said Statehouse sources say there is no political appetite to debate gay marriage on any level before May 17. Even Romney's bill giving him special permission to go before the Supreme Court to delay gay marriages has yet to be admitted to the Senate.
