Samuel Nelson, Dred Scott v. Sandford — Separate Opinion (1857)
“ But how is the case different on the return of the plaintiff to the State of Missouri? Is she bound to recognise and enforce the law of Illinois? For unless she is the status and condition of the slave upon his return remains the same as originally existed. Has the law of Illinois any greater force within the jurisdiction of Missouri than the laws of the latter within that of the former? Certainly not. They stand upon an equal footing. Neither has any force extraterritorially except what may be voluntarily conceded to them. ”
