Legal Residuum Rule Law and Legal Definition

Legal residuum rule states that the decision or order of an administrative agency should be supported by at least a small amount of evidence, which is not inadmissible hearsay, in order to be upheld on review.

Even though an administrative agency is not bound by the rules and evidence applicable in court and may accept, in its discretion, any evidence that is offered, still in the end there must be a residuum of legal evidence to support the finding of the administrative agency.
