Samuel Nelson, Sinnot v. Davenport — Opinion of the Court
“ Taking the term commerce in its broadest acceptation, supposing it to embrace not merely traffic, but the means and vehicles by which it is prosecuted, can it properly be made to include objects and purposes such as those contemplated by the law under review? Commerce with foreign nations must signify commerce, which in some sense is necessarily connected with those nations, transactions which, either immediately or at some stage of their progress, must be extra territorial. ”
