Summary

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.

Again, it seems to me that such an instruction would not give proper scope to the congressional intention that the taxpayer have a chance to prove 'by the preponderance of the evidence' that it had a 'contrary' purpose. I would therefore adopt an instruction less loaded against the taxpayer.
The Court of Appeals for the Sixth Circuit decided, and respondent argues, that the tax should apply only if the jury finds that tax avoidance was the 'dominant, controlling, or impelling motive' for the accumulation. I agree with the Court that such an instruction would be improper.

Finally, we cannot subscribe to respondent's suggestion that our holding would make purpose totally irrelevant. It still serves to isolate those cases in which tax avoidance motives did not contribute to the decision to accumulate. Obviously in such a case imposition of the tax would be futile. In addition, 'purpose' means more than mere knowledge, undoubtedly present in nearly every case. It is still open to the taxpayer to show that even though knowledge of the tax consequences was present, that knowledge did not contribute to the decision to accumulate earnings.
