Is a written notice of the proposed action a procedural due process or a substanstantive due process?

A written notice of the proposed action is primarily a matter of procedural due process. Procedural due process focuses on the fairness of the processes used to enforce laws and regulations, ensuring individuals are informed of actions that may affect their rights. It requires adequate notice and an opportunity to respond, thereby protecting individuals from arbitrary actions. Substantive due process, on the other hand, deals with the fundamental rights and liberties themselves, rather than the procedures in place to enforce them.
