Felix Frankfurter,
Secretary of Agriculture v. Central Roig Refining Company Porto Rican American Sugar Refinery…
“ In directing the Secretary to take into consideration ability to market, Congress in effect charged the Secretary with making a forecast of the marketers' capacity to perform in the immediate future. Such a forecast no doubt draws heavily on experience, but history never quite repeats itself even in the vicissitudes of industry. Whether ability to market is most rationally measured by plant capacity or by past performance, whether, if the latter, the base period should be a year and what year or a group of years and what group-these are not questions to be dealt with as statistical problems. ”
