Thurgood Marshall, United States v. Donruss Company…
“ Under these circumstances, the jury is very likely to believe that it must find the forbidden purpose and impose the tax whenever the Government shows that the taxpayer has accumulated earnings with knowledge of the resultant tax saving, irrespective of any contrary evidence put forward by the taxpayer. The approved instruction simply tells the jury that the taxpayer must have had a 'purpose' to avoid individual taxes. In everyday speech, we commonly say that a person has a 'purpose' to do something when he acts with knowledge that the thing will inevitably result. ”
