Florida Civics EOC Module 6 Landmark Supreme Court Cases: a complete overview of Marbury v. Madison, Plessy and Brown, Gideon and Miranda, Tinker, and United States v. Nixon

What Module 6 actually demands

Module 6 is the landmark Supreme Court cases the NGSSS Civics standards single out, all within Reporting Category 4 (Organization and Function of Government). The EOC almost always tests these the same way: it gives you a short description of a ruling or a scenario, and asks you to match it to the right case and its one big principle. The whole skill is a set of clean case-to-principle pairings, so this module rewards memorizing a tight summary of each case and not mixing them up.

This guide ties together the matching dot-point pages, each with its own practice questions: judicial review and Marbury v. Madison, the segregation cases Plessy and Brown, the rights of the accused in Gideon and Miranda, student speech in Tinker v. Des Moines, and United States v. Nixon.

Marbury v. Madison and judicial review

Marbury v. Madison (1803) established judicial review, the power of the courts to declare a law or government action unconstitutional. It is the judicial branch's main check on the other branches and the power the Court used to decide every other case here. This case is the foundation of the module.

Plessy and Brown: the segregation cases

Plessy v. Ferguson (1896) upheld racial segregation under the "separate but equal" doctrine. Brown v. Board of Education (1954) overturned that doctrine in public schools, ruling segregation unconstitutional under the equal protection clause of the Fourteenth Amendment because separate schools are inherently unequal. Remember: Plessy allowed segregation; Brown ended it in schools.

Gideon and Miranda: the rights of the accused

Gideon v. Wainwright (1963) guaranteed the right to a lawyer for those who cannot afford one (Sixth Amendment). Miranda v. Arizona (1966) required police to inform a suspect of their rights (to remain silent and to a lawyer) before questioning (Fifth and Sixth Amendments). Remember: Gideon = get a lawyer; Miranda = be told your rights.

Tinker: student speech

Tinker v. Des Moines (1969) protected students' symbolic speech (wearing armbands) under the First Amendment, declaring that students do not "shed their constitutional rights... at the schoolhouse gate." Schools may limit speech only if it substantially disrupts learning or harms others' rights, not simply because they dislike the message.

United States v. Nixon: limiting the president

United States v. Nixon (1974) reinforced the rule of law: no one, not even the president, is above the law. The Court limited executive privilege, ordering the president to release evidence in a criminal case. It is a clear example of the judicial branch checking the executive.
