Stephen Johnson Field,
Mahon v. Justice — Opinion of the Court
“ If the states of the Union were possessed of an absolute sovereignty, instead of a limited one, they could demand of each other reparation for an unlawful invasion of their territory and the surrender of parties abducted, and of parties committing the offense, and, in case of refusal to comply with the demand, could resort to reprisals, or take any other measures they might deem necessary as redress for the past and security* for the future. But the states of the Union are not absolutely sovereign. Their sovereignty is qualified and limited by the conditions of the Federal constitution. ”
