Hawaii's Supreme Court will be hearing oral arguments in a state Republican representative's lawsuit challenging the gay marriage law.

While the Legislature was considering the bill last year, Rep. Bob McDermott tried to stop the state from issuing any marriage licenses to same-sex couples. The circuit court denied his motion for a temporary restraining order and preliminary injunction. McDermott appealed.

McDermott's lawsuit says the Legislature didn't have authority to pass the law.

Arguments are scheduled for Thursday.

The state attorney general's office is defending the law. The office requested the case bypass the Intermediate Court of Appeals and go straight to the Supreme Court. Spokeswoman Anne Lopez says that was done out of a sense of urgency to resolve the case because more than 3,000 same-sex couples have already married.
