New Mexico State Rep. David Chavez on Tuesday introduced a proposed constitutional amendment which would define marriage as a heterosexual union.

If approved by lawmakers and voters in November, the amendment would bar the state from recognizing gay and lesbian couples with marriage, civil unions and possibly domestic partnerships.

Chavez, a freshman Republican representative, is an attorney from Los Lunas.

At its Wednesday meeting, the Santa Fe City Council approved a resolution sponsored by Councilwoman Patti Bushee opposing the measure, reported.

“The Santa Fe City Council stood with New Mexico families last night, and sent a clear message to legislators: that in New Mexico we celebrate diversity, we respect our neighbors, and we value our families. All of our families,” said Jacob Candelaria, president of Equality New Mexico.

Candelaria added that he hopes lawmakers will focus on the issues that matter most to New Mexicans.

“My sincere hope is that all legislators, including Rep. David Chavez, will spend their time focusing on what matters most to New Mexicans: education, jobs, and the economy,” he said.

In previous sessions, lawmakers have turned down bills to recognize gay couples with domestic partnerships.
