Prominent legal group Lambda Legal will file a federal lawsuit in West Virginia on Tuesday.

According to The Charleston Gazette, the group will hold a press conference at 10 AM in Huntington to discuss the lawsuit.

Lambda Legal is representing gay and lesbian couples seeking to marry in legal challenges filed in several states, including Illinois, Virginia and Nevada.

Casey Willits, executive director of Fairness West Virginia, confirmed to the paper that her group has been working with Lambda Legal, but would not discuss details of the suit.

“We've been working with them and looking at issues this summer regarding West Virginia and how it fits into federal legal precedent,” Willits said.

“I think we may be hearing about an important lawsuit on the constitution,” said Delegate Stephen Skinner, an openly gay Democrat from Jefferson.

A West Virginia statute limits marriage in the state to one man and one woman. Efforts to amend the state constitution to ban gay marriage have died in the Legislature.
