Republican leaders in the North Carolina legislature have vowed to continue fighting for the state's ban on gay marriage, which was struck down on Friday.

Four days after the Supreme Court refused to hear an appeal in a case from the Fourth Circuit striking down Virginia's ban, U.S. District Court Judge Max O. Cogburn Jr. said that the case had created “settled law” in the circuit and that North Carolina's ban violated the 14th Amendment of the U.S. Constitution. Joyous couples began marrying soon after Cogburn's ruling was released late Friday.

Cogburn denied a request by the GOP leaders to intervene in the case.

However, U.S. District Judge William Osteen is considering arguments in two similar cases and has yet to rule out allowing the leaders to intervene.

“While we recognize the tremendous passion on all sides of this issue, we promised to defend the will of North Carolina voters, because they – not judges and not politicians – define marriage as between one man and one woman and placed that in our state constitution,” North Carolina House Speaker Thom Tillis and Senate President Phil Berger said in a joint statement.

“It is disappointing this decision was made without North Carolina's law receiving its day in court, and we will continue to work to ensure the voice of the voters is heard,” they added.

Osteen has given plaintiffs in the cases until Monday at 3 PM to file their response.

Lawyers representing the GOP lawmakers have argued that Virginia's case should not affect North Carolina's outcome because Virginia's attorney general, Mark Herring, sided with plaintiff couples.
