The election on November 3 will decide a seat on the Ohio Supreme Court. Democrat Jennifer Brunner and Republican Colleen O’Donnell are running for a six-year term. Brunner is the incumbent candidate, while O’Donnell most recently served as a federal immigration judge in Laredo, Texas. Republican justices currently have a 6-1 majority on the Court.
In recent years, the Court allowed Ohio judges to publicly make political endorsements, allowed prosecutors to appeal when a judge sets aside a jury’s guilty verdict in a criminal case, and held the U.S. Supreme Court’s decision in Obergefell v. Hodges, which legalized same-sex marriage, could not be applied retroactively to determine child custody cases.
Matters that may come before the Court in the near future include one that could clarify requirements for renewable energy development in the state.
