The question to be determined in this case is whether the general assembly of Illinois can, under the limitations upon the legislative power of the States imposed by the Constitution of the United States, fix by law the maximum of charges for the storage of grain in warehouses at Chicago and other places in the State having not less than one hundred thousand inhabitants, 'in which grain is stored in bulk, and in which the grain of different owners is mixed together, or in which grain is stored in such a manner that the identity of different lots or parcels cannot be accurately preserved.'
It is claimed that such a law is repugnant—
1. To that part of sect. 8, art. 1, of the Constitution of the United States which confers upon Congress the power 'to regulate commerce with foreign nations and among the several States;'
2. To that part of sect. 9 of the same article which provides that 'no preference shall be given by any regulation of commerce or revenue to the ports of one State over those of another;' and
3. To that part of amendment 14 which ordains that no State shall 'deprive any person of life, liberty, or property, without due process of law, nor deny to any person within its jurisdiction the equal protection of the laws.'
We will consider the last of these objections first.
Every statute is presumed to be constitutional. The courts ought not to declare one to be unconstitutional, unless it is clearly so. If there is doubt, the expressed will of the legislature should be sustained.
The Constitution contains no definition of the word 'deprive,' as used in the Fourteenth Amendment. To determine its signification, therefore, it is necessary to ascertain the effect which usage has given it, when employed in the same or a like connection.
While this provision of the amendment is new in the Constitution of the United States, as a limitation upon the powers of the States, it is old as a principle of civilized government. It is found in Magna Charta, and, in substance if not in form, in nearly or quite all the constitutions that have been from time to time adopted by the several States of the Union. By the Fifth Amendment, it was introduced into the Constitution of the United States as a limitation upon the powers of the national government, and by the Fourteenth, as a guaranty against any encroachment upon an acknowledged right of citizenship by the legislatures of the States.
When the people of the United Colonies separated from Great Britain, they changed the form, but not the substance, of their government. They retained for the purposes of government all the powers of the British Parliament, and through their State constitutions, or other forms of social compact, undertook to give practical effect to such as they deemed necessary for the common good and the security of life and property. All the powers which they retained they committed to their respective States, unless in express terms or by implication reserved to themselves. Subsequently, when it was found necessary to establish a national government for national purposes, a part of the powers of the States and of the people of the States was granted to the United States and the people of the United States. This grant operated as a further limitation upon the powers of the States, so that now the governments of the States possess all the powers of the Parliament of England, except such as have been delegated to the United States or reserved by the people. The reservations by the people are shown in the prohibitions of the constitutions.
