Republican Nebraska Governor Pete Ricketts on Monday appealed a ruling striking down the state's ban on gay marriage.

U.S. District Judge Joseph Bataillon ordered officials to “treat same-sex couples the same as different sex couples in the context of processing a marriage license or determining the rights, protections, obligations or benefits of marriage” in a ruling handed down Monday morning. Bataillon stayed his order until March 9.

Ricketts, a defendant in the case, within an hour filed a notice of appeal in the case to the Eighth Circuit Court of Appeals in St. Louis.

The governor, whose openly lesbian sister, Laura Ricketts, co-owns the Chicago Cubs, said the issue should be left to the voters, not an “activist judge.”

“Today, a judge took steps to overturn a constitutional amendment approved by 70% of Nebraskans that defines marriage as between one man and one woman,” Ricketts said in a statement.

“The definition of marriage is an issue for the people of Nebraska, and an activist judge should not substitute his personal political preferences for the will of the people. I will continue to work with Attorney General Doug Peterson to uphold Nebraska’s Constitution and the will of the people of our great state,” he added.

Officials are expected to elaborate on their plans during a press conference scheduled to take place at 1:30 PM local time.
