Gay-rights advocates have asked a New Jersey judge not to delay implementation of her order that the state start allowing same-sex marriages this month.

Judge Mary Jacobson ruled last week the state must allow gay couples to marry beginning Oct. 21.

Republican Gov. Chris Christie's administration is appealing to the state Supreme Court and asking the order be put on hold in the meantime.

Gay-rights advocates on Friday filed court papers arguing the state hasn't shown irreparable harm if wedding licenses can be granted later this month or shown it's likely to win on appeal.

New Jersey has civil unions for gay couples but not marriages. Gay marriages are legal in 13 states, including most in the Northeast.
