Wyoming lawmakers are expected to consider a myriad of bills related to gay unions in the upcoming session, the Billings Gazette reported.

One measure would allow gay and lesbian couples to marry in the state, while another would recognized their relationships with civil unions.

A third bill would define marriage as a heterosexual union in the Wyoming Constitution.

Republicans Senator Curt Meier and Representative Owen Peterson are co-sponsoring the measure that would effectively ban gay marriage. Similar proposals in 2007 and 2009 failed, but anticipated support from a newly-elected Republican majority in both sides of the Capitol has given ban supporters renewed hope.

Gay marriage is currently not legal in Wyoming, but opponents worry that a legal challenge could overturn the statute. A lawsuit challenging Wyoming's law was filed in August. But less than a month later, the couple voluntarily withdrew its legal challenge.

State Representative Cathy Connolly, a Democrat from Laramie, is behind both pro-gay bills.

Connolly, the only openly gay member of the Wyoming Legislature, said she would prefer legalizing gay marriage over civil unions, but noted that gay marriage remains controversial.

“So many people find marriage to be a special category for male and female couples only, and some people are willing to support a civil unions bill,” she said.

Illinois joined New Jersey last month in legalizing civil unions. Gay activists in Hawaii are hopeful lawmakers will approve a similar law this year.
