Which legal principle protects property owners from arbitrary enforcement actions?

The legal principle that protects property owners from arbitrary enforcement actions is due process of law. This principle ensures that individuals are given fair treatment through the judicial system, including the right to notice and an opportunity to be heard before any governmental action that may affect their property rights. Due process requires that laws be applied fairly and consistently, meaning that property owners cannot be subjected to arbitrary or capricious enforcement actions without a clear legal basis or adequate procedure.

While equal protection under the law is important for preventing discrimination and ensuring that individuals are treated equally under the same laws, it does not specifically address the procedural safeguards that due process provides. The right to privacy, on the other hand, focuses on individuals' personal space and information and does not directly relate to property enforcement issues. Fair access to public services ensures that individuals can access services equally, but it does not directly address the protection against arbitrary government actions related to property. Thus, due process of law is the key principle that ensures property owners are protected from unjust enforcement actions.
