This case, however, strikingly illustrates the consequences that would follow the construction of the Constitution which would give the power contended for to a State. It would in effect give it also to an individual. For if the father of young Darnall had manumitted him in his lifetime, and sent him to reside in a State which recognised him as a citizen, he might have visited and sojourned in Maryland when he pleased, and as long as he pleased, as a citizen of the United States; and the State officers and tribunals would be compelled, by the paramount authority of the Constitution, to receive him and treat him as one of its citizens, exempt from the laws and police of the State in relation to a person of that description, and allow him to enjoy all the rights and privileges of citizenship, without respect to the laws of Maryland, although such laws were deemed by it absolutely essential to its own safety. The only two provisions which point to them and include them, treat them as property, and make it the duty of the Government to protect it; no other power, in relation to this race, is to be found in the Constitution; and as it is a Government of special delegated powers, no authority beyond these two provisions can be constitutionally exercised. The Government of the United States had no right to interfere for any other purpose but that of protecting the rights of the owner, leaving it altogether with the several States to deal with this race, whether emancipated or not, as each State may think justice, humanity, and the interests and safety of society, require. The States evidently intended to reserve this power exclusively to themselves.
