New Jersey Governor Chris Christie has filed an emergency appeal to the state Supreme Court after a judge refused to delay her ruling legalizing gay marriage in the state.

Superior Court Judge Mary Jacobson ruled on September 27 that the state must begin issuing marriage licenses to gay and lesbian couples as of October 21.

Christie, a Republican, appealed the order to the state Supreme Court and asked Jacobson to stay her decision until the matter is resolved. On Thursday, Jacobson denied the request, saying that the state was unlikely to win its appeal.

In its filing, the state argues that the decision should not be up to one judge.

“It is in the public interest that such a profound change, if it is to occur, take place not because a single judge – no matter how diligent, thoughtful, and thorough – ordered it, but rather because the Supreme Court, the ultimate arbiter, has deemed it necessary,” the AP quoted the state's brief as saying. “To overhaul such an ancient social institution prematurely, precipitously, or in a manner ultimately deemed unnecessary would injure not only the public interest, but the State that represents this interest.”

Garden State Equality, the state's largest LGBT rights advocate, and Lambda Legal are representing six gay couples and some of their children in the case.

Marriage equality supporters argue that the state's civil union law unfairly burdens gay and lesbian couples who cannot access federal benefits following the fall of the Defense of Marriage Act (DOMA) in June.

Christie's lawyers argue that the federal government should recognize the state's civil union law.
