Substantive due process

The term "substantive due process" (SDP) is commonly used in two ways: first to identify a particular line of case law, and second to signify a particular attitude toward judicial review under the Due Process Clause. The term "substantive due process" began to take form in 1930s legal casebooks as a categorical distinction of selected due process cases, and by 1950 had been mentioned twice in Supreme Court opinions. SDP involves liberty-based due process challenges which seek certain outcomes instead of merely contesting procedures and their effects; in such cases, the Supreme Court recognizes a constitutionally-based "liberty" which then renders laws seeking to limit said "liberty" either unenforceable or limited in scope. Critics of SDP decisions typically assert that those liberties ought to be left to the more politically accountable branches of government.
