A conclusion of law is a determination by a judge or ruling authority regarding the law that applies in a particular case. It is opposed to a finding of fact, which interprets the factual circumstances to which the law is to be applied. For example, a conclusion of law may determine that evidence cannot be introduced in a trial, based on evidentiary rules excluding illegally obtained evidence. The choice to believe a certain party's testimony regarding the circumstances about how the evidence was obtained is truthful is a finding of fact.
