The Ninth Amendment to the United States Constitution addresses rights, retained by the people, that are not specifically enumerated in the Constitution. It is part of the Bill of Rights. The amendment was introduced during the drafting of the Bill of Rights when some of the American founders became concerned that future generations might argue that, because a certain right was not listed in the Bill of Rights, it did not exist. However, the Ninth Amendment has rarely played any role in U.S. constitutional law, and until the 1980s was often considered "forgotten" or "irrelevant" by many legal academics.
The Fourteenth Amendment to the United States Constitution was adopted on July 9, 1868, as one of the Reconstruction Amendments. Usually considered one of the most consequential amendments, it addresses citizenship rights and equal protection under the law and was proposed in response to issues related to formerly enslaved Americans following the American Civil War. The amendment was bitterly contested, particularly by the states of the defeated Confederacy, which were forced to ratify it in order to regain representation in Congress. The amendment, particularly its first section, is one of the most litigated parts of the Constitution, forming the basis for landmark Supreme Court decisions such as Brown v. Board of Education (1954) regarding racial segregation, Roe v. Wade (1973) regarding abortion, Bush v. Gore (2000) regarding the 2000 presidential election, Obergefell v. Hodges (2015) regarding same-sex marriage, and Students for Fair Admissions v. Harvard (2023) regarding race-based college admissions. The amendment limits the actions of all state and local officials, and also those acting on behalf of such officials.
Civil liberties are guarantees and freedoms that governments commit not to abridge, either by constitution, legislation, or judicial interpretation, without due process. Though the scope of the term differs between countries, civil liberties may include the freedom of conscience, freedom of press, freedom of religion, freedom of expression, freedom of assembly, the right to security and liberty, freedom of speech, the right to privacy, the right to equal treatment under the law and due process, the right to a fair trial, and the right to life. Other civil liberties include the right to own property, the right to defend oneself, and the right to bodily integrity. Within the distinctions between civil liberties and other types of liberty, distinctions exist between positive liberty/positive rights and negative liberty/negative rights.
Griswold v. Connecticut, 381 U.S. 479 (1965), was a landmark decision of the U.S. Supreme Court in which the Court ruled that the Constitution of the United States protects the liberty of married couples to use contraceptives without government restriction. The case involved a Connecticut "Comstock law" that prohibited any person from using "any drug, medicinal article or instrument for the purpose of preventing conception". The court held that the statute was unconstitutional, and that its effect was "to deny disadvantaged citizens ... access to medical assistance and up-to-date information in respect to proper methods of birth control." By a vote of 7–2, the Supreme Court invalidated the law on the grounds that it violated the "right to marital privacy", establishing the basis for the right to privacy with respect to intimate practices. This and other cases view the right to privacy as "protected from governmental intrusion".

Lochner v. New York, 198 U.S. 45 (1905), was a landmark decision of the U.S. Supreme Court holding that a New York State statute that prescribed maximum working hours for bakers violated the bakers' right to freedom of contract under the Fourteenth Amendment to the U.S. Constitution. The decision has been effectively overturned.
Substantive due process is a principle in United States constitutional law that allows courts to establish and protect certain fundamental rights from government interference, even if they are unenumerated elsewhere in the U.S. Constitution. Courts have asserted that such protections come from the due process clauses of the Fifth and Fourteenth amendments to the U.S. Constitution, which prohibit the federal and state governments, respectively, from depriving any person of "life, liberty, or property, without due process of law". Substantive due process demarks the line between those acts that courts hold to be subject to government regulation or legislation and those that courts place beyond the reach of governmental interference. Whether the Fifth or Fourteenth Amendments were intended to serve that function continues to be a matter of scholarly as well as judicial discussion and dissent. In recent opinions, Justice Clarence Thomas has called on the Supreme Court to reconsider all of its rulings that were based on substantive due process.
A Due Process Clause is found in both the Fifth and Fourteenth Amendments to the United States Constitution, which prohibit the deprivation of "life, liberty, or property" by the federal and state governments, respectively, without due process of law.
The Equal Protection Clause is part of the first section of the Fourteenth Amendment to the United States Constitution. The clause, which took effect in 1868, provides "nor shall any State ... deny to any person within its jurisdiction the equal protection of the laws." It mandates that individuals in similar situations be treated equally by the law.
In United States constitutional law, incorporation is the doctrine by which portions of the Bill of Rights have been made applicable to the states. When the Bill of Rights was ratified, the courts held that its protections extended only to the actions of the federal government and that the Bill of Rights did not place limitations on the authority of the state and local governments. However, the post–Civil War era, beginning in 1865 with the Thirteenth Amendment, which declared the abolition of slavery, gave rise to the incorporation of other amendments, applying more rights to the states and people over time. Gradually, various portions of the Bill of Rights have been held to be applicable to state and local governments by incorporation via the Due Process Clause of the Fourteenth Amendment of 1868.
In United States law, the Establishment Clause of the First Amendment to the United States Constitution, together with that Amendment's Free Exercise Clause, form the constitutional right of freedom of religion. The relevant constitutional text is:
Congress shall make no law respecting an establishment of religion...
The Lochner era was a period in American legal history from 1897 to 1937 in which the Supreme Court of the United States is said to have made it a common practice "to strike down economic regulations adopted by a State based on the Court's own notions of the most appropriate means for the State to implement its considered policies". The court did this by using its interpretation of substantive due process to strike down laws held to be infringing on economic liberty or private contract rights. The era takes its name from a 1905 case, Lochner v. New York. The beginning of the era is usually marked earlier, with the Court's decision in Allgeyer v. Louisiana (1897), and its end marked forty years later in the case of West Coast Hotel Co. v. Parrish (1937), which overturned an earlier Lochner-era decision.
Adamson v. California, 332 U.S. 46 (1947), was a United States Supreme Court case regarding the incorporation of the Fifth Amendment of the Bill of Rights. Its decision is part of a long line of cases that eventually led to the Selective Incorporation Doctrine.
Palko v. Connecticut, 302 U.S. 319 (1937), was a United States Supreme Court case concerning the incorporation of the Fifth Amendment protection against double jeopardy.
Fundamental rights are a group of rights that have been recognized by a high degree of protection from encroachment. These rights are specifically identified in a constitution, or have been found under due process of law. The United Nations' Sustainable Development Goal 16, established in 2015, underscores the link between promoting human rights and sustaining peace.
The Privileges or Immunities Clause is Amendment XIV, Section 1, Clause 2 of the United States Constitution. Along with the rest of the Fourteenth Amendment, this clause became part of the Constitution on July 9, 1868.
Washington v. Glucksberg, 521 U.S. 702 (1997), was a landmark decision of the U.S. Supreme Court, which unanimously held that a right to assisted suicide in the United States was not protected by the Due Process Clause.
Cantwell v. Connecticut, 310 U.S. 296 (1940), is a landmark court decision by the United States Supreme Court holding that the First Amendment's federal protection of religious free exercise incorporates via the Due Process Clause of the Fourteenth Amendment and so applies to state governments too.
Obergefell v. Hodges, 576 U.S. 644 (2015), is a landmark decision of the Supreme Court of the United States which ruled that the fundamental right to marry is guaranteed to same-sex couples by both the Due Process Clause and the Equal Protection Clause of the Fourteenth Amendment of the Constitution. The 5–4 ruling requires all fifty states, the District of Columbia, and the Insular Areas to perform and recognize the marriages of same-sex couples on the same terms and conditions as the marriages of opposite-sex couples, with all the accompanying rights and responsibilities. Prior to Obergefell, same-sex marriage had already been established by statute, court ruling, or voter initiative in thirty-six states, the District of Columbia, and Guam.
