On November 21, 2016, Judge Ripple, joined by District Judge Barbara Brandriff Crabb found that the high number of wasted votes created by the 2011 Wisconsin State Assembly redistricting was unconstitutional partisan gerrymandering, over dissent by District Judge William C. Griesbach.^[2]

In October 2018, Ripple dissented when the majority, in an opinion by Chief Judge Diane Wood, found that Tony Evers, then Superintendent of Public Instruction of Wisconsin, did not violate the Constitution's Free Exercise Clause nor its Establishment Clause when he denied bussing to an independent catholic school because there was a nearby archdiocesan school.^[3][4]
