She has been arguing that, as a Christian, she should not have to follow state rules about judicial impartiality.

A Texas judge is asking a federal court to overturn marriage equality in the U.S., arguing in a lawsuit filed on Friday that marriage for same-sex couples is unconstitutional because it was legalized in a decision that “subordinat[ed] state law to the policy preferences of unelected judges.”

The case involves Judge Dianne Hensley of Waco, Texas, who has been involved in years of legal proceedings to try to win the right to not perform marriages for same-sex couples while still performing them for opposite-sex couples. She claims that, as a Christian, she should not have to follow state judicial ethics rules about impartiality.
