Louis Brandeis, Snyder v. Commissioner of Internal Revenue…
“ Neither in the findings of the Board of Tax Appeals, nor in the facts upon which the case was submitted to it, is there any support for the controverted allegation in Snyder's petition that his market operations constituted a 'business regularly carried on for profit.' [1] It is true that a taxpayer may be engaged in more than one trade or business, as those terms are used in various provisions of the Revenue Acts ”
