The lawsuit, filed by Gay and Lesbian Advocates & Defenders, challenges a September ruling by state Attorney General Tom Reilly that found the amendment drive was legal.
That ruling allowed backers of the amendment to begin collecting signatures. They gathered more than 120,000 -- well above the 65,000 needed to get the measure on the 2008 ballot.
Gary Buseck, GLAD legal director, said the Massachusetts Constitution bars any citizen-initiated amendment that ''relates to the reversal of a judicial decision.'' Reilly should have blocked the question from going forward on those grounds, Buseck said.
The proposed amendment is designed ''squarely and solely'' to reverse the landmark 2003 decision by Massachusetts' high court that legalized gay marriage, Buseck said.
