The Fourteenth Amendment of the U.S. Constitution contains a number of important concepts, most famously state action, privileges or immunities, citizenship, due process, and equal protection—all of which are contained in Section One.
Governmental actors violate due process when they frustrate the fairness of proceedings, such as when a prosecutor fails to disclose evidence to a criminal defendant that suggests they may be innocent of the crime, or when a judge is biased against a criminal defendant or a party in a civil action.
A major provision of the 14th Amendment was to grant citizenship to “All persons born or naturalized in the United States,” thereby granting citizenship to formerly enslaved people.
No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
The Fourteenth Amendment's Due Process Clause provides that no state may deprive any person of life, liberty, or property, without due process of law.
Thus public school segregation based on race was found in violation of the 14th Amendment's Equal Protection Clause. Mapp v.
