Ohio R. Prac. S. Ct. 4.03
If the Supreme Court, sua sponte or on motion by a party, determines that an appeal or other action is frivolous or is prosecuted for delay, harassment, or any other improper purpose, it may impose appropriate sanctions on the person who signed the appeal or action, a represented party, or both. The sanctions may include an award to the opposing party of reasonable expenses, reasonable attorney fees, costs or double costs, or any other sanction the Supreme Court considers just. An appeal or other action shall be considered frivolous if it is not reasonably well-grounded in fact or warranted by existing law or a good-faith argument for the extension, modifi cation, or reversal of existing law.
If a party habitually, persistently, and without reasonable cause engages in frivolous conduct under division (A) of this rule, the Supreme Court may, sua sponte or on motion by a party, find the party to be a vexatious litigator. If the Supreme Court determines that a party is a vexatious litigator under division (A) of this rule, the court may impose fi ling restrictions on the party. The restrictions may include prohibiting the party from continuing or instituting legal proceedings in the Supreme Court without first obtaining leave, prohibiting the filing of actions in the Supreme Court without the filing fee or security for costs required by S.Ct.Prac.R. 3.04 and 3.05, or any other restriction the Supreme Court considers just.
