It was further provided that wherever in consequence of any State or local law any of the civil rights or immunities belonging to white persons, such as the right to enforce contracts, to sue, to give evidence, to inherit, purchase, lease, sell, hold or convey real and personal property, were refused or denied to freedmen on account of race or color or any previous condition of slavery or involuntary servitude, or whenever they were subjected to punishment for crime different from that provided for white persons, it was made the duty of the President, through the Commissioner, to extend military jurisdiction and protection over all cases affecting persons against whom such unjust discriminations were made. It was made the duty of the officers and agents of the Bureau to take jurisdiction of and to hear and determine all cases, in which by local law discrimination was made against the freedmen. This was to be done under such rules and regulations as the President, through the Commissioner, might prescribe. But the jurisdiction was to cease "whenever the discrimination on account of which it is conferred shall cease," and was in no event to be exercised in any State "in which the ordinary course of judicial proceeding has not been interrupted by the Rebellion, nor in those States after they shall have been fully restored to their constitutional relations to the United States, and when the courts of the State and of the United States, within their limits, are not disturbed or stopped in the peaceable course of justice." In the time of peace, these provisions seemed extraordinary, but the condition of affairs, in the judgment of leading Republican statesmen, justified their enactment. The Thirteenth Amendment, about to be formally promulgated by the Executive Department of the Government, as incorporated in the Constitution, had made every negro a free man. The Southern States had responded to this Act of National authority by enacting a series of laws which really introduced, as has already been shown, a new, offensive and most oppressive form of servitude. Thus not only was rank injustice contemplated by the States lately in rebellion, but they conveyed also an insulting challenge to the authority of the Nation. It was as if they had said to the National Government: "In order to destroy the Confederacy and restore the Union you have manumitted these black men; but we will demonstrate to you, by our local legislation, that you are powerless to give them any further freedom than we are willing to concede, and we defy you to show by what means you can achieve it!"
