John Marshall Harlan II,
United States v. Carlo Bianchi and Company…
“ The term 'substantial evidence' in particular has become a term of art to describe the basis on which an administrative record is to be judged by a reviewing court. This standard goes to the reasonableness of what the agency did on the basis of the evidence before it, for a decision may be supported by substantial evidence even though it could be refuted by other evidence that was not presented to the decision-making body. ”
