Joseph Story,
Armstrong v. Kosciuszko — Opinion of the Court
“ The treaty stipulations, the act of Congress, and the principles of the law of France, which have been cited at the argument, attributing to them the full force which that argument supposes to establish the validity of the instrument, do not change the forum which is entitled, by the local jurisprudence, to pronounce upon it as a testamentary paper, and to grant a probate. It is one thing to possess proofs, which may be sufficient to establish that a testamentary instrument had been executed in a foreign country, under circumstances which ought to give it legal effect here ”
