George Sutherland, Helvering v. Grinnell — Opinion of the Court
“ The contention of the government is that the tax is imposed 'upon the power to transmit or the transmission of property by death; the shifting of the economic benefits in property is the real subject of the tax. * * * The property in question passed to the sisters under the general power of appointment exercised by the decedent by will within the meaning of the statute.' But this involves the obviously self-destructive conclusion that an unsuccessful attempt to effectuate a thing required by the statute is the same as its consummation. ”
