Procedural due process asks a two-step question. First, is a protected liberty or property interest actually at stake -- not every disappointment or denial rises to that level; property interests often arise from an independent source, such as a statute, regulation, or contract, that creates a legitimate claim of entitlement, while liberty interests can include physical freedom, certain reputational harms combined with a tangible loss, and other recognized categories. Second, if such an interest is at stake, what process is constitutionally due before the government may take it away.

This doctrine is distinct from substantive due process, which asks whether the government may take the action at all, regardless of the procedure used. Procedural due process assumes the government might be entitled to act, and asks only whether it followed a fair process in getting there.

Because not every government decision implicates due process, the threshold inquiry is whether the plaintiff has a legally protected liberty or property interest, rather than a mere unilateral expectation or hope. Courts look to independent sources of law -- statutes, regulations, employment rules, contracts -- to determine whether they create a legitimate claim of entitlement sufficient to trigger constitutional protection.

Once a protected interest is established, courts typically balance three factors to determine what process is constitutionally required: the private interest affected by the government action; the risk of an erroneous deprivation through the procedures used, and the likely value of additional or substitute safeguards; and the government's interest, including the administrative and fiscal burdens that additional procedures would impose. The result can range from a full pre-deprivation hearing to a more limited notice-and-opportunity-to-respond, or in some circumstances only a prompt post-deprivation remedy.

A plaintiff must establish both the protected interest and that the process actually provided fell short of what the balancing test requires. A defendant typically argues either that no protected interest existed in the first place, or that the process actually afforded -- whether pre-deprivation or a prompt post-deprivation remedy -- was constitutionally adequate given the balance of interests.

Procedural due process decomposes cleanly into two sequential questions, which makes it well suited to explicit claim-path modeling. In Juricratic terms, the interest-exists question and the process-was-adequate question can be modeled as two linked decision nodes, each with its own dial, so a user can see how the claim's viability -- and the remedy it can realistically support, which is often only better process rather than damages -- shifts as the strength of each element changes independently.
