Four same s*x couple have pleaded for class-action lawsuit to legalize same-s*x marriage in Arizona.

The lawsuit, filed on Monday, claimed that voter-approved ban on gay-marriage is not constitutional and that same-s*x marriage should be institutionalized in Arizona like other states.

"I think most people expect that this issue will eventually be decided by the U.S. Supreme Court," attorney Shawn Aiken, who filed the suit.

Gov. Jan Brewer and Attorney General Tom Horne are the other two defendants.

The lawsuit claims that certain "rights and benefits are denied to gay couples because Arizona doesn't recognize their marriages."

There was no immediate response on Monday night from either Brewer's or Horne's offices.
