Bob Ellis, leader of the South Dakota Tea Party Alliance, has attacked the federal judge who struck down South Dakota's ban on gay marriage.

In a 28-page ruling released Monday, U.S. District Judge Karen E. Schreier said gay couples have a “fundamental right to marry” and that the state's 1996 law and 2006 constitutional amendment limiting marriage to heterosexual unions “deprives them of that right solely because they are same-sex couples without sufficient justification.”

Schreier stayed her ruling.

In op-ed published Tuesday by conservative websites and, Ellis claimed that Schreier had “taken upon herself to attack the institution of marriage.”

“United States District Court Judge Karen E. Schreier, a President Bill Clinton appointee with ties to former Democrat Senator Tim Johnson, has taken it upon herself to attack the institution of marriage, the South Dakota Constitution, and pour contempt on the will of the people of South Dakota who voted in 2006 to affirm in our state constitution what every civilization throughout human history has understood instinctively: that marriage can only be formed by a man and a woman,” Ellis wrote. “This kind of judicial activism, perversion of the U.S. Constitution (intended to prevent Democrats from undermining morality and the rule of law), the South Dakota Constitution, and pure contempt for the people of South Dakota and our republican form of government (which does NOT empower judges to make law), should not be allowed to stand.”

Photos accompanying the piece included one of two bolts labeled “counterfeit marriage” and one of a bolt and a nut labeled “real marriage.”
