Rule of Law:
An assignor of income-producing property who retains substantial power to control the property and the flow of income remains liable for taxes on that income. Furthermore, the doctrine of collateral estoppel does not apply to a tax case involving a later year if there has been a significant intervening change in the controlling legal principles.
Facts:
- Joseph Sunnen, an inventor, was the president and majority shareholder of Sunnen Products Company, owning 89% of its stock.
- Sunnen entered into several non-exclusive license agreements with his company, which allowed it to manufacture his patented devices in exchange for a 10% royalty on sales.
- The agreements did not require minimum royalty payments and could be cancelled by either party with six months' or one year's written notice.
- Sunnen assigned all his rights, title, and interest in these license contracts to his wife, Cornelia Sunnen, as gifts, without receiving any consideration.
- After the assignments, the company paid the royalties directly to Cornelia Sunnen.
- Sunnen retained ownership of the underlying patents for the devices covered by the license agreements.
Procedural Posture:
- In a 1935 proceeding for prior tax years, the Board of Tax Appeals (the Tax Court's predecessor) ruled that Joseph Sunnen was not taxable on royalties paid to his wife under a 1928 license agreement.
- For the tax years 1937-1941, the Commissioner of Internal Revenue assessed tax deficiencies against Sunnen, arguing he was taxable on royalties paid to his wife from all license agreements.
- Sunnen petitioned the Tax Court, which held he was taxable on royalties from newer contracts but that collateral estoppel barred taxing him on royalties from the 1928 contract.
- Both Sunnen and the Commissioner appealed to the U.S. Court of Appeals for the Eighth Circuit.
- The Eighth Circuit court of appeals affirmed on the collateral estoppel issue but reversed on the merits, holding that Sunnen was not taxable on any of the royalties.
- The Commissioner of Internal Revenue petitioned the U.S. Supreme Court for a writ of certiorari, which was granted.

Issue:
Does an inventor who assigns royalty license contracts to his wife remain taxable on the royalties paid to her if he retains substantial control over both the corporation paying the royalties and the contracts themselves?
Opinions:
Majority - Justice Murphy
Yes, the inventor remains taxable on the royalties. The assignment of income-producing property does not shift tax liability when the assignor retains substantial control over the property or the receipt of income. First, the doctrine of collateral estoppel does not bar taxing the royalties from the 1928 contract, despite a prior ruling in the taxpayer's favor. An intervening development in the controlling legal principles, specifically the Supreme Court's 'Clifford-Horst' line of cases on intra-family assignments, represents a change in the 'legal atmosphere' sufficient to make collateral estoppel inapplicable. For the other contracts not previously litigated, collateral estoppel does not apply as they constitute different causes of action. On the merits, an assignment within a family requires special scrutiny. Here, Sunnen retained significant control: 1) as the 89% stockholder, he could control the corporation and effectively procure the cancellation of the license agreements; 2) he could regulate the amount of royalties by controlling the company's manufacturing and sales policies; 3) he owned the patents and could license them to other companies; and 4) the assignment did not substantially change his economic status as the income remained within the family unit. These retained powers mean the transaction was a mere reallocation of income, and he remains the true earner for tax purposes.
Dissenting - Justices Frankfurter and Jackson
No, the judgment of the Tax Court should be affirmed. The dissenters did not issue a full opinion but stated they would affirm the Tax Court's judgment because it was based on substantial evidence and was consistent with the law, citing the deferential standard of review from cases like Dobson v. Commissioner.
Analysis:
This landmark decision significantly curtails the use of collateral estoppel in tax litigation, establishing that an intervening change in controlling case law can prevent a prior judgment from binding subsequent tax years. This prevents the perpetuation of outdated legal interpretations and ensures uniform application of tax laws. Substantively, the case reinforces the 'assignment of income' doctrine by focusing on retained control rather than the formalities of title transfer, making it a cornerstone case for analyzing income-shifting attempts, particularly within family arrangements involving intellectual property.
