Owen J. Roberts, Helvering v. City Bank Farmers Trust Company…
“ It is competent for Congress, in order to avoid the evasion of tax, to declare that when one has placed his property in trust subject to a right of revocation in himself and another who is not the beneficiary he shall, nevertheless, be deemed to control the property in such sense that the income therefrom shall be treated as his income for the levying of a tax. ”
