When, therefore, the application of such guarantees as are found in the Fifth and Fourteenth Amendments of the Federal Constitution, and in article 23 of the Maryland Declaration of Rights, is considered, it must be with due regard to the principle that the State, in the exercise of what is usually called its police power, may regulate or restrict the freedom of the individual to act, when such regulation or restraint is essential to the protection of the public safety, health, or morals. That power, however, is itself subject to the restraints imposed by constitutions which the whole people have adopted and approved as the supreme law of the land. 12 C. J. 928, 929; State v.

Crowther, supra), and the legislature may not, under the cloak of the police power, exercise a power forbidden by the Constitution (State v. Hyman, supra), or take away rights and privileges expressly guaranteed by it.
Among those privileges are these: That the individual shall not be deprived of his life, liberty, or property without due process of law; and that the individual is entitled to the equal protection of the law.
