In Universal Camera Corp. v. Labor Bd. (1951) 340 U.S. 474, the United States Supreme Court extensively reviewed the National Labor Relations Act, wherein the same language is found. The court rejected the concept that courts could determine the substantiality of the evidence to support a board's decision merely on the basis of evidence which in and of itself justified it, without taking into account contradictory evidence or evidence from which conflicting inferences could be drawn (at p. 487 95 L.Ed. at p. 467). The court stated, "The substantiality of evidence must take into account whatever in the record fairly detracts from its weight" (at p. 488). The court went on to say, "The Board's findings are entitled to respect; but they must nonetheless be set aside when the record before a Court of Appeals clearly precludes the Board's decision from being justified by a fair estimate of the worth of testimony of witnesses or its informed judgment on matters within its special competence or both" (at p. 490).
