It is not necessary to attempt any exact definitions within which the acts of such a State government must be treated as valid or invalid. It may be said, perhaps with sufficient accuracy, that acts necessary to peace and good order among citizens, such for example, as acts sanctioning and protecting marriage and the domestic relations, governing the course of descents, regulating the conveyance and transfer of property, real and personal, and providing remedies for injuries to person and estate, and other similar acts, which would be valid if emanating from a lawful government must be regarded in general as valid when proceeding from an actual, though unlawful, government, and that acts in furtherance or support of rebellion against the United States, or intended to defeat the just rights of citizens, and other acts of like nature, must, in general, be regarded as invalid and void.
