Alabama Supreme Court Chief Justice Roy S. Moore is calling on two Supreme Court justices to recuse themselves from an upcoming case challenging gay marriage bans.

The high court has agreed to hear cases challenging bans in four states: Ohio, Tennessee, Michigan and Kentucky. The court consolidated the cases and scheduled oral arguments for April 28, with a decision expected in June.

Moore told on Thursday that Justices Ruth Bader Ginsburg and Elena Kagan should removed themselves from the case because each has married gay couples.

“Their actions speak louder than their words,” Moore said.

Moore is an outspoken opponent of marriage equality. He attempted to block a federal judge's ruling declaring unconstitutional Alabama's ban by ordering probate judges to ignore the ruling. A majority of judges initially followed Moore's directions but most later reversed course. Moore has also said that he would not follow a Supreme Court order invalidating restrictive state marriage bans.

On Tuesday, the Alabama Supreme Court ordered probate judges to stop issuing such licenses.

Moore is the latest conservative to call for Kagan and Ginsburg to recuse themselves in the case. However, like those before him, Moore is not asking conservative justices to step down. Justice Antonin Scalia has made his opposition clear. In 2013, Scalia told a group of lawyers that there is no right to “homosexual conduct” in the United States Constitution. Also, if marrying couples is the yardstick by which we measure impartiality, then we should note that Justice Clarence Thomas officiated at the wedding of conservative commentator Rush Limbaugh and Marta Maranda Fitzgerald. The marriage lasted a decade. In 2010, Limbaugh married his fourth wife, Kathryn Rogers.
