Anthony Kennedy,
Portland Golf Club v. Commissioner of Internal Revenue…
“ If profit motivation turns upon the allocation method employed by the club in filling out its tax forms, then the status of the nonmember activity as a trade or business may lie within the control of the club's accountants. I find this interpretation of the words "trade or business" simply "to affront common understanding and to deny the facts of common experience." Helvering v. Horst, 311 U.S. 112, 118, 61 S.Ct. 144, 147, 85 L.Ed. 75 (1940) . A taxpayer does not alter the nature of an enterprise by selecting one reasonable allocation method over another. ”
