Mahlon Pitney, United States v. Field — Opinion of the Court
“ Field at the time of her death, nor subject to distribution as part of her estate, was not taxable under clause (a) .We deem it equally clear that it was not within clause (b) . That clause is the complement of (a) , and is aptly descriptive of a transfer of an interest in decedent's own property in his lifetime, intended to take effect at or after his death. It cannot, without undue laxity of construction, be made to cover a transfer resulting from a testamentary execution by decedent of a power of appointment over property not his own. ”
