Same-sex marriage advocates asked the Supreme Court on Tuesday to quash a new Mississippi law that lets businesses and government workers reject services to LGBT people because of their religious objections.

The advocates' request to the high court came soon after the Mississippi law went into effect Tuesday, the Associated Press reported.

The legislation, "Protecting Freedom of Conscience from Government Discrimination Act," defines marriage as between one man and one woman, says sex is "properly reserved" to people in such a marriage, and that man and woman refer to someone's biological sex as determined by their birth.
