What is substantive due process concerned with?

Substantive due process is primarily concerned with the protection of fundamental liberty interests. This aspect of due process focuses on whether the government has a sufficient justification for infringing on individual rights, particularly those deemed essential to the notion of ordered liberty. It addresses the content or the substance of laws and governmental actions, ensuring that certain rights, such as privacy, marriage, and family relations, are protected from arbitrary interference.

The concept of substantive due process emerged from a recognition that not all laws that restrict personal freedoms are legitimate; they must also serve a legitimate purpose and not infringe upon fundamental rights without a compelling justification. This principle plays a significant role in cases where individuals argue that their basic rights are being violated by government action, emphasizing that certain rights are so fundamental that they are safeguarded against governmental violations, regardless of the procedures that may be followed in enforcing those laws.

Other options, while related to legal concepts, do not address the specific focus of substantive due process. Enforcement methods of laws, fair trial guarantees, and procedural fairness primarily deal with the processes and mechanisms of law enforcement and judicial proceedings rather than the protection of intrinsic personal freedoms.
