The phrase due-process of law means that:

The phrase "due-process of law" refers to the legal requirement that the government must respect all of a person's legal rights when it comes to legal proceedings. It is enshrined in the Fifth and Fourteenth Amendments to the U.S. Constitution and serves as a safeguard against arbitrary denial of life, liberty, or property. This means that individuals are entitled to fair treatment through the normal judicial system, especially in the context of criminal prosecutions.

Understanding this concept emphasizes that due process provides protection from illegal or unfair acts by the government, ensuring that individuals have the right to a fair trial, adequate legal representation, and an opportunity to defend themselves in a lawful manner. The essence of due process is to uphold the rule of law and prevent abuse of power by the authorities, thus securing individual rights against improper governmental interference.
