Due process is the legal requirement that the state must respect all legal rights that are owed to a person. Due process balances the power of law of the land and protects the individual person from it. When a government harms a person without following the exact course of the law, this constitutes a due process violation, which offends the rule of law.
Due process has also been frequently interpreted as limiting laws and legal proceedings so that judges, instead of legislators, may define and guarantee fundamental fairness, justice, and liberty. That interpretation has proven controversial. Analogous to the concepts of natural justice, and procedural justice used in various other jurisdictions, the interpretation of due process is sometimes expressed as a command that the government must not be unfair to the people or abuse them physically.
Due process of law doctrine not only checks if there is a law to deprive the life and personal liberty of a person but also see if the law made is fair, just and not arbitrary. If SC finds that any law as not fair, it will declare it as null and void. This doctrine provides for more fair treatment of individual rights. Under due process, it is the legal requirement that the state must respect all of the legal rights that are owed to a person and laws that states enact must conform to the laws of the land like – fairness, fundamental rights, liberty etc. It also gives the judiciary to access fundamental fairness, justice, and liberty of any legislation. Each amendment contains a due process clause, which prohibits the government from taking any action that would deprive a person of “life, liberty, or property without due process of law." The due process clause provides several types of protection.
