Keith Bardwell, a white justice of the peace in Tangipahoa Parish in the southeastern part of the state, refused to issue a marriage license earlier this month to Beth Humphrey, who is white, and Terence McKay, who is black. His refusal has prompted calls for an investigation or resignation from civil and constitutional rights groups and the state's Legislative Black Caucus.
Republican Gov. Bobby Jindal said in a statement a nine-member commission that reviews lawyers and judges in the state should investigate.
"Disciplinary action should be taken immediately - including the revoking of his license," Jindal said.
Bardwell did not return calls left on his answering machine Friday.
Bardwell has said he always asks if a couple is interracial and, if they are, refers them to another justice of the peace. Bardwell said no one had complained in the past and he doesn't marry the couples because he's worried about their children's futures.
"Perhaps he's worried the kids will grow up and be president," said Bill Quigley, director of the Center for Constitutional Rights and Justice, referring to President Barack Obama, the son of a black father from Kenya and a white mother from Kansas.
Obama's deputy press secretary Bill Burton echoed those sentiments.
"I've found that actually the children of biracial couples can do pretty good," Burton told reporters aboard Air Force One as it flew to Texas.
Humphrey and McKay were eventually married by another justice of the peace, but are now looking into legal action against Bardwell.
Humphrey said she called Bardwell on Oct. 6 to ask about a marriage license. She said Bardwell's wife told her that Bardwell would not sign marriage licenses for interracial couples.
Bardwell maintains he can recuse himself from marrying people. Quigley disagreed.
"A justice of the peace is legally obligated to serve the public, all of the public," Quigley said. "Racial discrimination has been a violation of Louisiana and U.S. law for decades. No public official has the right to pick and choose which laws they are going to follow."
A spokeswoman for the Louisiana Judiciary Commission said investigations were confidential and would not comment. If the commission recommends action to the Louisiana Supreme Court, the matter would become public.
