Procedural and substantive due process are two aspects of the constitutional concept of "due process" outlined in the Fifth and Fourteenth Amendments that (theoretically) guarantees a form of fairness through consistent use of constitutional and legal safeguards.
Many constitutional scholars contend that the Fifth Amendment was intended only to guarantee procedural due process, to place limits on the government's ability to deprive a person of "life, liberty, or property" without taking certain protective steps on behalf of the individual, as outlined in the Bill of Rights (more specifically the Fifth and Sixth Amendments). Examples include the right to a jury trial, right to confront witnesses against him (or her), protection against being tried for the same crime twice, protection against involuntary self-incrimination, right to the effective assistance of counsel, and so on.
Substantive due process, as expounded by 17th-century English jurist Sir Edward Coke, deals with liberty interests, or the right of people to live without unnecessary and arbitrary government interference.
In the United States, Congress exercised the concept of substantive due process in the Missouri Compromise of 1820, which abolished slavery in Federal Territories. The Missouri Compromise gave rise to the doctrine of "once free, always free," holding once a slave had lived in "free" territory, his (or her) liberty could not be revoked (he or she could not be re-enslaved). The Supreme Court temporarily squashed this notion in Dred Scott v. Sandford, (1857), when it held the Missouri Compromise unconstitutional and ruled slaves were property, not people with rights.
More recently, the Supreme Court has divided liberty (substantive) interests into two categories: the first are those expressly enumerated in the Constitution, such as the First Amendment freedom of speech and religion; the second involve fundamental liberties not specifically listed but still considered essential to living in a free and just society, such as the right to privacy, and more abstract concepts such as the right to personal autonomy (within certain parameters) and dignity.
Procedural due process deals with governmental methods and how they are used, whereas substantive due process deals with the fairness of laws.
The two categories of due process are substantive due process and procedural due process. Substantive due process relates to liberty interests protected by the Constitution; procedural due process ensures legal proceedings are conducted in a fair and consistent manner.For more information, see Related Questions, below.

Procedural due process has to do with the how (the procedures, the methods) of governmental action. Substantive due process involves the what (the substance, the policies of governmental action).
substantive due process
procedural due process focuses on the fairness of the legal process itself in ensuring individual rights are protected, while substantive due process addresses the actual content or substance of the laws being applied and their impact on individual liberties.
Substantive due process addresses a law's fairness, while procedural due process addresses how a law is implemented.
The Fifth Amendment's Due Process Clause has two aspects: procedural and substantive
due process
It's substantive due process.
constitutional
The Supreme Court added the concept of substantive due process to address concerns about the protection of fundamental rights that were not explicitly enumerated in the Constitution. While procedural due process focuses on the fairness of legal proceedings, substantive due process ensures that laws and government actions do not infringe on basic rights, such as privacy and personal autonomy. This expansion aimed to safeguard individual liberties against arbitrary government interference, reflecting a growing recognition of the importance of personal freedoms in a rapidly industrializing society.
