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, Loving v. Virginia (1967) regarding interracial marriage, 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.
Baker v. Carr, 369 U.S. 186 (1962), was a landmark United States Supreme Court case in which the Court held that redistricting qualifies as a justiciable question under the Fourteenth Amendment's equal protection clause, thus enabling federal courts to hear Fourteenth Amendment-based redistricting cases. The court summarized its Baker holding in a later decision as follows: "the Equal Protection Clause of the Fourteenth Amendment limits the authority of a State Legislature in designing the geographical districts from which representatives are chosen either for the State Legislature or for the Federal House of Representatives.". The court had previously held in Gomillion v. Lightfoot that districting claims over racial discrimination could be brought under the Fifteenth Amendment.

Sims, 377 U.S. 533 (1964), was a landmark United States Supreme Court case in which the Court ruled that the electoral districts of state legislative chambers must be roughly equal in population.

Gray v. Sanders, 372 U.S. 368 (1963), was a Supreme Court of the United States case dealing with equal representation in regard to the American election system and formulated the famous "one person, one vote" standard applied in this case for "counting votes in a Democratic primary election for the nomination of a United States Senator and statewide officers — which was practically equivalent to election."

This slogan is used by advocates of democracy and political equality, especially with regard to electoral reforms like universal suffrage and proportional representation.

In the Matter of the Marriage of J.B. and H.B. was a case arising from a divorce petition filed by a same-sex couple in Texas. They had been married in Massachusetts. A Texas Family Court granted the petition, holding that Texas's Proposition 2, which prohibited the court from recognizing a same-sex marriage, violated the due process and equal protection guarantees of the Fourteenth Amendment to the United States Constitution. On appeal, the Fifth Court of Appeals of Texas reversed the family court's judgment, holding that it was consistent with the due process and equal protection clauses. The case was before the Texas Supreme Court, but the case was dismissed due to the death of one of the parties.
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.

Bank Markazi v. Peterson, 578 U.S. 212 (2016), was a United States Supreme Court case that found that a law which only applied to a specific case, identified by docket number, and eliminated all of the defenses one party had raised does not violate the separation of powers in the United States Constitution between the legislative (Congress) and judicial branches of government. The plaintiffs, in the case had initially obtained judgments against Iran for its role in supporting state-sponsored terrorism, particularly the 1983 Beirut barracks bombings and 1996 Khobar Towers bombing, and sought execution against a bank account in New York held, through European intermediaries, on behalf of Bank Markazi, the Central Bank of the Islamic Republic of Iran. The plaintiffs obtained court orders preventing the transfer of funds from the account in 2008 and initiated their lawsuit in 2010. Bank Markazi raised several defenses, including that the account was not an asset of the bank, but rather an asset of its European intermediary, under both New York state property law and §201(a) of the Terrorism Risk Insurance Act. In response to concerns that existing laws were insufficient for the account to be used to settle the judgments, Congress added an amendment to a 2012 bill, codified after enactment as 22 U.S.C. § 8772, that identified the pending lawsuit by docket number, applied only to the assets in the identified case, and effectively abrogated every legal basis available to Bank Markazi to prevent the plaintiffs from executing their claims against the account. Bank Markazi then argued that § 8772 was an unconstitutional breach of the separation of power between the legislative and judicial branches of government, because it effectively directed a particular result in a single case without changing the generally applicable law. The United States District Court for the Southern District of New York and, on appeal, the United States Court of Appeals for the Second Circuit both upheld the constitutionality of § 8772 and cleared the way for the plaintiffs to execute their judgments against the account, which held about $1.75 billion in cash.
Heffernan v. City of Paterson, 578 U.S. ___ (2016), was a United States Supreme Court case in 2016 concerning the First Amendment rights of public employees.

Harris v. Arizona Independent Redistricting Commission, 578 U.S. ___ (2016), was a United States Supreme Court case in which the Court held that the one person, one vote principle under the Equal Protection Clause of the Fourteenth Amendment allows a state's redistricting commission slight variances in drawing of legislative districts provided that the variance does not exceed 10 percent. The Court found that the map, created by a bipartisan commission on the basis of the 2010 census, was constitutional.
