Overrule may refer to a judge's disagreement with an attorney's objection to a question to a witness or admission of evidence. By overruling the objection, the trial judge allows the question or evidence in court. If the judge agrees with the objection, he/she "sustains" the objection and does not allow the question or evidence. Overrule may also refer to an appeals court overturning a previous ruling on a legal issue, so that the prior decision is no longer a valid precedent on that legal question. In general, overrule refers to disallowing the action or arguments of someone, especially by virtue of higher authority.
