Felix Frankfurter,
National Labor Relations Board v…
“ It is not for us to invite review by this Court of decisions turning solely on evaluation of testimony where on a conscientious consideration of the entire record a Court of Appeals under the new dispensation finds the Board's order unsubstantiated. In such situations we should 'adhere to the usual rule of non-interference where conclusions of Circuit Courts of Appeals depend on appreciation of circumstances which admit of different interpretations'. ”
