The civil rights group that campaigned for marriage equality in Vermont said on Thursday that its work is done and it's disbanding.

The Vermont Freedom to Marry Task Force was formed in 1996 by Beth Robinson and Susan Murray. Robinson is now a Vermont Supreme Court justice.

In 2009, Vermont became the first state to approve a marriage law that includes gay and lesbian couples without court intervention.

Lawmakers approved the state's first-in-the-nation civil unions law after the Vermont Supreme Court in 1999 ruled that the Vermont Constitution entitles gay couples to “the same benefits and protections” afforded to married opposite-sex couples but stopped short of ordering the state to begin issuing marriage licenses to gay couples.

“Even after Vermont achieved in-state marriage equality in 2009, we felt it was important to keep standing for the principle that equality shouldn't depend on where you live,” Sheryl Rapee, the group's chairwoman, said in a press release.

“When the marriages of Vermont same-sex couples received federal recognition after DOMA was struck down in 2013, that was one step closer,” she continued. “When the U.S. Supreme Court ruled in favor of nationwide marriage equality, our goal was truly met. With the elimination of the unfair patchwork of marriage laws across the U.S., families of married same-sex Vermont couples were no longer under threat beyond state lines. We knew then it was time to begin archiving our history and, most importantly, to say thank you to all of Vermont Freedom to Marry’s supporters over the years.”

“Vermont's leadership role in the marriage equality movement provides a hopeful example of what can be accomplished when people join together with determination and perseverance to gain civil rights,” the group added.
