Louis Brandeis, Helvering v. Mitchell — Opinion of the Court
“ The sanction of fine and imprisonment prescribed by section 146 (b) for willful attempts 'in any manner to evade or defeat any (income) tax,' introduced into the act under the heading 'Penalties,' is obviously a criminal one. The sanction of 50 per centum addition 'if any part of any deficiency is due to fraud with intent to evade tax,' prescribed by section 293 (b) , introduced into the act under the heading 'Additions to the tax,' was clearly intended as a civil one. ”
