A walk through the whole topic. The difference between civil and constitutional rights, the four routes through which rights have been defended, the cases and laws that built and unbuilt the American rights regime, and the question behind every Q3c essay: who actually protects rights in the United States?
The 2025 Paper 3 USA examiner report opened its analysis of Question 3(c) with a warning: "a significant minority of candidates" did not understand the difference between civil rights and constitutional rights, and that confusion ran through the rest of their essays. This walk-through starts there. It distinguishes the two kinds of right, then maps the four routes by which both have been defended in the United States, the landmark cases and laws on a single timeline, the case for and against the Supreme Court as the principal defender, and the role of social movements, Congress and the executive alongside it. The exam question of how successfully rights have been upheld runs through the whole.
The distinction the examiner expects you to know before anything else.
Constitutional rights are the rights set out in the US Constitution and its amendments. The First Amendment protects free speech, religion, assembly and the press. The Second protects the right to bear arms. The Fourth protects against unreasonable searches. The Fifth and Sixth protect the rights of the accused. The Fourteenth, ratified after the Civil War in 1868, extends due process and equal protection of the laws to all persons under state jurisdiction. These are the rights every citizen holds against any level of government, and the Supreme Court is their principal interpreter.
Civil rights are protections against discrimination, usually on the basis of group membership. They overlap with constitutional rights, but they have a different history. Civil rights have been built primarily through legislation (the 1964 Civil Rights Act, the 1965 Voting Rights Act, the 1990 Americans with Disabilities Act) and through court interpretation of the Fourteenth Amendment's Equal Protection Clause. They are usually about who gets to enjoy constitutional rights in practice - the right to vote (in principle, in the Constitution; in practice, fought for through legislation and the streets).
The Supreme Court, Congress, the President, and the people. Scroll - each takes a turn.
Rights in the United States have been defended through four distinct routes. The diagram beside you holds them. The Q3c question typically pits the Supreme Court against the others, but the strongest essays note how often the routes feed each other - a movement creates the political pressure, Congress passes the law, the President signs and enforces, and the Court rules on the result.
Rights are defended through four institutions: the Supreme Court, Congress, the President and the people themselves through movements and interest groups. The diagram beside you holds them. The Q3c essay usually weighs the Court against the others; the honest answer recognises how often they feed each other.
The Court interprets the Constitution and can strike down laws that conflict with it. Marbury v Madison (1803) established judicial review. Brown v Board of Education (1954) is the textbook example: a unanimous ruling that "separate educational facilities are inherently unequal" overturned Plessy v Ferguson and dismantled the legal basis for segregation. The Court can move where Congress cannot, and it can move faster - but its rulings depend on enforcement by other branches, and on later courts not reversing them.
Congress writes the statutes that turn constitutional principles into civil rights. The Civil Rights Act 1964 outlawed discrimination on the basis of race, colour, religion, sex and national origin in public accommodations and employment. The Voting Rights Act 1965 banned literacy tests and required federal preclearance for changes to voting law in jurisdictions with histories of discrimination. The 1990 Americans with Disabilities Act protected disabled Americans. Congressional statute is the route that has built the strongest practical civil-rights regime - and the route the Court has, since 2013, partially dismantled.
Presidents have defended rights through executive orders, federal enforcement and judicial appointments. Truman integrated the armed forces by executive order in 1948. Eisenhower sent federal troops to enforce Brown in Little Rock in 1957. Lyndon Johnson drove the 1964 Civil Rights Act and 1965 Voting Rights Act through Congress and signed both. Obama's 2012 DACA order extended deportation relief to undocumented young people. Executive power cuts both ways - the Trump administration's 2017 travel ban (upheld in Trump v Hawaii) and 2025 immigration enforcement show the route used to restrict rights as well as to extend them.
The change in American rights has been driven from below as much as from above. The Civil Rights Movement - the Montgomery Bus Boycott 1955-56, the March on Washington 1963, the Selma marches 1965 - created the political pressure that produced the great civil rights statutes. The NAACP built the litigation strategy that produced Brown. The ACLU defends individual rights in court. The marriage equality movement of the 2000s laid the ground for Obergefell. Black Lives Matter after 2013 and the post-Dobbs reproductive rights movement after 2022 are the contemporary equivalents.
The 1964 Civil Rights Act is unintelligible without the Civil Rights Movement; Brown is unintelligible without the NAACP litigation strategy; Obergefell is unintelligible without forty years of activism. The 2025 examiner report warned against the simplistic positive/negative approach in Q3c. A strong essay says which route delivered which right, and recognises that the most durable victories came when more than one route worked together.
One hundred and thirty years of rights cases and rights laws. Scroll the timeline beside you.
The story is not a straight line. The Court that decided Plessy in 1896 was the Court that decided Korematsu in 1944; the Court that decided Brown in 1954 was the Court that decided Loving in 1967; the Court that decided Obergefell in 2015 was the Court that decided Dobbs in 2022. The 2025 examiner report flagged "chronological confusion" as a common AO1 error. The timeline beside you fixes the order in your mind.
Three eras divide the modern rights story. The retreat (1865-1945): the Reconstruction promise broken, Jim Crow, Plessy, Korematsu. The expansion (1954-2015): Brown, the civil rights statutes, Loving, Roe, Obergefell. The contemporary retrenchment (2010-): Citizens United, Shelby County, Dobbs, Bruen, SFFA. Scroll the milestones.
The 13th, 14th and 15th Amendments (1865-70) ended slavery, guaranteed equal protection and gave Black men the right to vote. By 1896 the Court had retreated. Plessy v Ferguson upheld "separate but equal" segregation, and Jim Crow regimes dominated the South for six decades. The retreat reached its low point in Korematsu v United States (1944), which upheld the internment of Japanese Americans during the Second World War. The Court at its worst is the Court that wrote these two opinions.
In a unanimous opinion by Chief Justice Earl Warren, the Court ruled that "separate educational facilities are inherently unequal" and overturned Plessy. Brown v Board of Education of Topeka is the textbook example of judicial defence of rights. But Brown took three years to produce an enforcement order (Brown II, 1955, "with all deliberate speed"), and segregation remained the de facto rule in most Southern schools for a decade afterwards. The Court can name the right; enforcement comes from elsewhere.
The Montgomery Bus Boycott (1955-56), the Greensboro sit-ins (1960), the Freedom Rides (1961), Martin Luther King's "I have a dream" speech at the March on Washington (1963), the Selma to Montgomery marches (1965). The movement created the conditions for the Civil Rights Act 1964 (LBJ, racial discrimination outlawed in public accommodations and employment) and the Voting Rights Act 1965 (federal preclearance for changes to voting law in jurisdictions with discriminatory histories).
A run of landmark cases extended rights into criminal procedure and personal life. Mapp v Ohio (1961): exclusionary rule binds the states. Gideon v Wainwright (1963): right to a lawyer in felony cases. Miranda v Arizona (1966): the warnings every American TV viewer knows. Loving v Virginia (1967): interracial marriage bans struck down on Fourteenth Amendment grounds. The Warren Court built the modern constitutional-rights regime.
The Court found a constitutional right to abortion grounded in the right to privacy implied by the Fourteenth Amendment. Roe v Wade set a trimester framework and produced fifty years of one of the most consequential and contested rulings in American history. It was reaffirmed in Planned Parenthood v Casey (1992) on stare decisis grounds. It was overturned in 2022.
By a 5-4 majority, the Court found a constitutional right to same-sex marriage in the Due Process and Equal Protection clauses of the Fourteenth Amendment. Obergefell followed decades of marriage equality activism and a fast change in public opinion. It is the high-water mark of the expansion era - and crucially, it comes BEFORE Dobbs, not after. The 2025 examiner report singled out that chronological confusion as a common error.
A series of rulings from a more conservative Court has rolled back rights once thought secure. Citizens United v FEC (2010): corporate spending in elections is protected speech. Shelby County v Holder (2013): gutted the Voting Rights Act preclearance regime, the 2025 ER's named example of misquoted impact. DC v Heller (2008) and NY State Rifle v Bruen (2022): an individual right to bear arms, strengthened. Trump v Hawaii (2018): third version of the travel ban upheld. Students for Fair Admissions v Harvard (2023): affirmative action in university admissions ended.
By 6-3 (5-4 on overruling), the Court overturned Roe v Wade and Planned Parenthood v Casey, finding no constitutional right to abortion. Dobbs v Jackson Women's Health Organisation returned the question to the states. Within a year, more than a third of US states had banned or severely restricted abortion. Dobbs is the most consequential retrenchment ruling of the modern era - and the strongest single case for the answer that the Court does NOT always uphold rights.
The retrenchment story is not a straight one, but the line has hardened. In Allen v Milligan (June 2023), the conservative majority surprised observers by voting 5-4 to preserve Section 2 of the Voting Rights Act in Alabama redistricting, requiring the state to draw a second majority-Black district. In 2024 the Court delivered two rulings centred on Trump himself. Trump v Anderson (March 2024) reversed the Colorado Supreme Court's disqualification of Trump from the ballot under Section 3 of the Fourteenth Amendment, reading the insurrection clause narrowly. Trump v United States (July 2024) granted broad immunity to former presidents for "official acts". Then on 29 April 2026, Louisiana v Callais reversed the Milligan moment: a 6-3 majority struck down Louisiana's second majority-Black district as a racial gerrymander and reinterpreted Section 2 to require something close to proof of intentional discrimination - Justice Kagan called it "all but a dead letter" in dissent. The Court is conservative; it is now consistently so on rights claims; and the most consequential current rulings are about presidential power and the practical death of the Voting Rights Act.
Plessy to Brown to Loving to Obergefell traces an arc of expansion. Brown to Shelby to Dobbs to SFFA traces an arc of retrenchment. The Court is not a single institution making a single judgement; it is a sequence of courts producing a sequence of rulings, each one the work of nine appointed individuals with political histories. The 2025 ER's central message: cite the cases accurately, in chronological order, and let the trajectory do the analytical work.
Five strands of evidence that the Supreme Court has upheld rights successfully.
The strongest defence of the Court as a defender of rights rests on a run of decisions that named rights other branches would not. The diagram beside you holds them by theme - the 2025 examiner report named affirmative action, women's rights, states' rights, gun control and the ideological balance of the court as the standard thematic frames.
The Court has named rights other institutions would not. Five strands: school desegregation, criminal procedure, marriage rights, free speech, and federalism. Scroll through them.
Brown v Board of Education (1954) overturned Plessy and produced the legal basis for ending state-mandated segregation. The ruling was unanimous and the language was uncompromising. Brown did not produce immediate desegregation - it took federal intervention at Little Rock in 1957 and Congressional action in 1964 - but it set the constitutional principle. No other institution could have moved this fast. Congress in 1954 could not have passed an anti-segregation statute; the President could not have ordered desegregation by executive action alone.
The Warren Court built the procedural-rights regime that defines US criminal law. Mapp v Ohio (1961) applied the exclusionary rule to the states. Gideon v Wainwright (1963) created the right to counsel for the indigent. Miranda v Arizona (1966) required the warnings. These rights are now so embedded that they are part of the cultural background of American policing. All four come from the Court, not from Congress.
Marriage rights are the Court at its boldest. Loving v Virginia (1967) struck down interracial marriage bans on Fourteenth Amendment grounds. Obergefell v Hodges (2015) found a constitutional right to same-sex marriage. Both rulings ran ahead of national legislatures - in 1967 a majority of Americans still opposed interracial marriage; in 2015 marriage equality had only just achieved majority approval. The Court named rights the political process was slower to recognise.
First Amendment doctrine in the United States is more protective of speech than in any comparable democracy, and it is the Court that built that. NYT v Sullivan (1964) created the "actual malice" standard that protects criticism of public figures. Brandenburg v Ohio (1969) set the modern test for incitement. Texas v Johnson (1989) protected flag-burning as symbolic speech. Free-speech rights, in the US sense, are an almost wholly judicial creation.
Federalism cuts both ways - the Court has used it to defend state autonomy AND, through the incorporation doctrine and Section 1 of the Fourteenth Amendment, to apply federal constitutional protections to state actions. McDonald v Chicago (2010) applied the Second Amendment to the states. The same incorporation logic underwrites every Bill of Rights protection that runs against state government. The Court is the institution that makes the Bill of Rights live at every level.
The Court has, on a long view, named rights other institutions would not. Brown, Gideon, Miranda, Loving, Obergefell are the cases the case is made on. Without the Court, the United States rights regime is unrecognisable. The question is whether the same Court can be relied on to keep doing this work - the next part is the answer.
Six strands of rulings the Court got wrong, or has reversed.
The 2025 examiner report singled out Dobbs as a key contemporary example, and warned against treating the Court as straightforwardly successful. The case against has six strands - the historical failures, the campaign finance ruling, the voting-rights retreat, abortion, guns, and the politicisation of appointments itself.
The Court is not consistently a defender of rights. Six strands of evidence make the case against: the historic rulings, campaign finance, voting rights, abortion, gun policy, and the increasingly partisan appointments process. Scroll through them.
Plessy v Ferguson (1896) legalised segregation for sixty years. Korematsu v United States (1944) upheld the internment of more than a hundred thousand Japanese Americans solely on the basis of race. The Court at its worst delivered these rulings; neither was forced by the Constitution. The Court is the institution that defended Brown - and also the institution that defended Plessy and Korematsu. The same machinery can produce either.
Citizens United v FEC (2010) held that corporate and union spending on election advocacy is protected speech under the First Amendment. The ruling produced the modern Super PAC and, in one reading, the wholesale capture of US elections by wealthy donors. Critics argue the case turned a procedural right (free speech) into a substantive harm to political equality. The Court's broad reading of the First Amendment can constrain Congress from regulating money in politics in ways most democracies do without difficulty.
The Voting Rights Act 1965 had two main enforcement engines. Section 4(b) and Section 5 between them required federal preclearance of any voting law change in jurisdictions with a history of discrimination. Shelby County v Holder (2013) struck down Section 4(b)'s formula and effectively killed preclearance: Chief Justice Roberts argued the formula was based on outdated conditions; critics replied that the formula was outdated only because the law had worked.
Section 2 of the VRA, which lets plaintiffs sue over discriminatory voting rules, survived Shelby but was narrowed by Brnovich v DNC (2021). Against expectations, Allen v Milligan (June 2023) then held 5-4 that Alabama's congressional map diluted Black votes in violation of Section 2, requiring Alabama to draw a second majority-Black district. For two years, Section 2 looked alive.
Then on 29 April 2026, Louisiana v Callais changed the position. Louisiana had complied with Milligan by drawing a second majority-Black district; non-Black voters challenged the new map as a racial gerrymander under the Fourteenth Amendment's Equal Protection Clause. The Court ruled 6-3 (Alito for the majority, Kagan in dissent) that Louisiana's map was an unconstitutional racial gerrymander, and that Section 2 had not actually required it. Crucially, the majority reinterpreted Section 2 to impose liability only when "circumstances give rise to a strong inference that intentional discrimination occurred" - reversing the discriminatory-effects framework that had governed Section 2 cases since Thornburg v Gingles (1986). Kagan called the ruling "all but a dead letter" for Section 2.
The current position, mid-2026: preclearance is dead, and Section 2 is effectively dead in all but the clearest intent cases. Congressional restoration (the John Lewis Voting Rights Advancement Act) remains blocked by the Senate filibuster. The Voting Rights Act of 1965 has, in practice, been hollowed out by three rulings of the same Court over thirteen years - Shelby, Brnovich, Callais - with Milligan a brief and now overtaken exception.
Dobbs v Jackson Women's Health Organisation (2022) overturned Roe v Wade (1973) and Planned Parenthood v Casey (1992), ruling that no constitutional right to abortion exists. Within a year, more than a third of US states had banned or severely restricted abortion access. Justice Thomas's concurrence questioned the constitutional basis of contraception and same-sex marriage rulings on the same logic. Dobbs is the strongest contemporary case for the proposition that the Court can take rights away as well as deliver them.
DC v Heller (2008) held that the Second Amendment protects an individual right to bear arms unconnected with militia service - a historic reinterpretation. NY State Rifle and Pistol Association v Bruen (2022) struck down New York's century-old "proper cause" requirement for concealed carry permits and required gun regulations to have a historical analogue from 1791 or 1868. The result has been a wave of lower-court rulings striking down state gun laws. For those who see gun proliferation as a rights problem, the Court has trended consistently in the wrong direction.
The Fourteenth Amendment (1868) is the most-cited amendment in modern rights cases, and the single best illustration that the Court can take rights in either direction. Its Equal Protection Clause produced Brown (1954), Loving (1967) and Obergefell (2015). The same clause was used in Students for Fair Admissions v Harvard (2023) to strike down race-conscious university admissions, and again in Louisiana v Callais (29 April 2026) to strike down a state map that had been drawn to remedy historical vote dilution. A clause written to protect newly freed Black citizens, now used to prevent the state from drawing districts that protect Black voters' political power - the same Equal Protection logic that defended desegregation, now wielded against race-conscious remedies. Its Due Process Clause produced Roe (1973), Lawrence v Texas (2003) on same-sex intimacy, and Obergefell again. The same clause was the route by which Dobbs (2022) ruled there is no constitutional right to abortion, because abortion is not "deeply rooted in this Nation's history and tradition". Section 3, on insurrection, was tested in Trump v Anderson (2024) and read so narrowly that no state can act unilaterally on it. The same amendment can defend rights and dismantle them; the variable is not the text but the Court.
The Court's record cannot be separated from how its justices are chosen. The 2016 refusal to hold hearings for Merrick Garland followed by the 2020 confirmation of Amy Coney Barrett a week before an election produced a 6-3 conservative majority that delivered Dobbs, Bruen and SFFA in quick succession. The 2025 ER warned against mislabelling justices Republican or Democrat - the proper terms are conservative and liberal - but the underlying point holds: the ideological balance of the Court matters more than ever, and the political process by which it is set has broken down.
The Court is not an institution that consistently defends rights. It is an institution whose record on rights is shaped by who sits on it. A strong essay says when and on which rights the Court has upheld them, and when and on which rights it has not. That, the 2025 ER stressed, is what AO3 evaluation looks like.
Movements, Congress, the executive. Where the Court fell short, or moved too late, others moved.
The Q3c question rewards essays that note the Court is not the only defender of rights and often not the most effective. Three other routes have done foundational work: social movements, congressional legislation and executive action. Each has produced rights gains the Court did not, and each has rolled them back as well. The diagram beside you holds them.
Three other routes have delivered rights victories the Court did not, or could not, deliver alone. Movements created the political pressure; Congress wrote the binding statutes; the executive enforced and sometimes initiated. Scroll through them.
Brown did not desegregate American schools - that took the Civil Rights Movement and federal enforcement. The Montgomery Bus Boycott (1955-56), the Greensboro sit-ins (1960), the Freedom Rides (1961), the March on Washington (1963) and the Selma marches (1965) created the political conditions for the 1964 Civil Rights Act and the 1965 Voting Rights Act. Black Lives Matter after 2013 has changed policing politics in dozens of states. The contemporary post-Dobbs reproductive rights movement is rebuilding access state by state.
Congress has built the strongest practical rights protections in American law. The Civil Rights Act 1964 outlawed discrimination by race, colour, religion, sex and national origin. The Voting Rights Act 1965 protected the franchise. The Title IX provision of the 1972 Education Amendments banned sex discrimination in federally funded education. The Americans with Disabilities Act 1990 protected disabled Americans. The Respect for Marriage Act 2022 codified federal recognition of same-sex marriage after the Dobbs concurrence threatened Obergefell. When Congress moves, the protection is more durable than when the Court alone names a right.
Presidents have used executive orders to extend rights faster than legislation could. Truman integrated the armed forces in 1948. Eisenhower sent federal troops to Little Rock in 1957. Lyndon Johnson drove the great civil rights statutes through. Obama's 2012 DACA order protected undocumented young people who had been brought to the US as children. Executive orders can also restrict rights: Trump v Hawaii (2018) upheld the travel ban; the 2025 Trump administration's first-day actions on immigration enforcement and federal hiring show the route in restrictive mode.
Interest groups bridge the routes. The NAACP Legal Defense Fund built the litigation strategy that produced Brown - decades of careful case selection and amicus work, not a single court ruling. The ACLU defends individual rights across the spectrum. The Federalist Society, founded in 1982, built the conservative judicial talent pipeline that produced the 6-3 majority responsible for Dobbs. Movements need lawyers and lawyers need movements - the most successful rights campaigns combine both.
The 2025 examiner report rewarded essays that interwove evaluation rather than splitting into a positive section and a negative section. The honest answer is that no single institution defends rights in the United States. Brown was meaningless without enforcement; the 1964 Civil Rights Act was unimaginable without the movement; Obergefell built on years of activism. The Court is one defender; sometimes the lead defender; sometimes the obstacle to defence. A strong essay names which case, which right, and which institution did the work.
The real questions this topic produces, and the traps the 2025 examiner report named.
Paper 3 USA examines this topic as a Section A short comparison and as a 30-mark essay (Q3). The 2025 Q3c is reproduced below as the anchor question.
Trap (named by the 2025 ER): understand civil v constitutional rights from the first sentence. Avoid the simplistic positive/negative split - interweave evaluation throughout. Use a thematic approach (affirmative action, women's rights, states' rights, gun control, ideological balance) and back each theme with two named, dated, accurately-described cases. Do NOT chain unconnected rights (do not compare abortion with gun control). Get chronology right: Obergefell 2015 came BEFORE Dobbs 2022. Reach a clear interim judgement per theme that ties back to "successfully".
Trap: "most important" demands comparison. Use Part 6 to set the Court against Congress, executive and movements. Argue the Court has been the most important on some rights (criminal procedure, marriage, free speech) but not others (civil rights enforcement, which needed legislation and movements). The strongest answers refuse to pick one institution.
Trap: "in recent years" - confine the analysis to roughly the last fifteen years to keep the focus. Use Part 5: Citizens United, Shelby County, Trump v Hawaii, Dobbs, Bruen, SFFA. Counter with Obergefell 2015, Bostock 2020. Argue the contemporary trend is restrictive but acknowledge the marriage and LGBTQ employment wins.
Trap: the question is about the appointments process and the conservative-liberal alignment of the Court, not partisanship in the everyday sense. Use Garland/Barrett, the 6-3 majority, the speed of recent retrenchments. Counter with cross-ideological rulings (Bostock 2020 with Gorsuch in the majority; the 2024 Trump immunity case as both/and). Reach a verdict that says "politicised but not yet partisan in a strict sense".
Approach: name the four routes from Part 2 - Supreme Court, Congress, executive, movements - and give one named example of a right each route delivered. Avoid the trap of treating "rights" as one undifferentiated thing.
Approach: both rest on the Fourteenth Amendment (Equal Protection and Due Process); both ran ahead of national legislatures; both required years of activism beforehand; both produced backlash. The differences (unanimous vs 5-4; immediate enforcement difficulty vs comparatively smooth implementation) are where most marks live, but the question asks for similarities first.
Three comparative themes - each pits the affirmative case against the counter on the same right or institutional question, so AO3 evaluation interweaves throughout (the 2025 ER directly warns against the simple positive/negative split).
Other comparative themes you could substitute: ideological balance against judicial restraint (Garland / Barrett against historical balance); states' rights against individual rights (the MS line that "states' rights have been upheld at the expense of individual rights"); activist Court against restrained Court (using Bruen's history-and-tradition test as the contemporary example); gun rights specifically (Heller and Bruen against Rahimi 2024).
You have walked the topic. Now check your recall and structure your answers.
The vocabulary the examiner expects you to define and use.
Constitutional rights - rights set out in the US Constitution and its amendments; apply to all persons against the government.
Civil rights - protections against discrimination, usually built through legislation and the Fourteenth Amendment's Equal Protection Clause.
Bill of Rights - the first ten amendments to the Constitution, ratified 1791.
Fourteenth Amendment - 1868 amendment, the most-cited in modern rights cases and the most clearly double-edged. Section 1 contains the Equal Protection Clause (Brown, Loving, Obergefell; also SFFA 2023, used to end affirmative action) and the Due Process Clause (Roe; also Dobbs 2022, used to overturn Roe). Section 3, on insurrection, was tested in Trump v Anderson 2024 and read narrowly. Section 5 empowers Congress to enforce, but its reach has been limited by the Court since the 1990s. The same amendment can expand rights or retract them - what matters is which Court reads it.
Voting Rights Act 1965 - federal statute banning literacy tests and (originally) requiring federal preclearance for voting changes in covered jurisdictions. Section 4(b) (the preclearance formula) was struck down in Shelby County v Holder 2013. Section 2, allowing suit over discriminatory voting laws, was narrowed in Brnovich v DNC 2021, briefly reaffirmed in Allen v Milligan 2023, and then reinterpreted in Louisiana v Callais 2026 to require something close to proof of intentional discrimination - in the Kagan dissent's phrase, "all but a dead letter". Restoration legislation (John Lewis Voting Rights Advancement Act) has been blocked in the Senate by the filibuster.
Thornburg v Gingles (1986) - established the discriminatory-effects test that governed Section 2 vote-dilution cases for forty years. Overtaken in practice by the intent test introduced in Louisiana v Callais 2026.
Allen v Milligan (2023) - 5-4 ruling holding Alabama's congressional map diluted Black votes in violation of VRA Section 2; required Alabama to draw a second majority-Black district. Effectively overtaken by Louisiana v Callais three years later.
Louisiana v Callais (29 April 2026) - 6-3 ruling (Alito for the majority, Kagan in dissent) striking down Louisiana's second majority-Black district as a racial gerrymander under the Fourteenth Amendment's Equal Protection Clause. Reinterpreted Section 2 of the VRA to impose liability only when "circumstances give rise to a strong inference that intentional discrimination occurred", reversing the discriminatory-effects framework from Thornburg v Gingles (1986). Kagan in dissent: "all but a dead letter" for Section 2.
Trump v Anderson (2024) - the Court reversed Colorado's removal of Trump from the ballot under the Fourteenth Amendment Section 3 (insurrection disqualification), holding that states cannot enforce Section 3 unilaterally against federal candidates.
Trump v United States (2024) - held that former presidents have broad immunity from criminal prosecution for "official acts" while in office. Not directly a rights case, but consequential for the constitutional balance between accountability and executive power.
Judicial review - the power of the courts to strike down legislative or executive acts that conflict with the Constitution; established Marbury v Madison 1803.
Incorporation doctrine - the route by which the Bill of Rights is applied to state governments, via the Fourteenth Amendment.
Strict scrutiny - the most demanding standard the Court applies to government action that burdens fundamental rights or uses suspect classifications (race).
Stare decisis - the principle of following past precedent; cited heavily in Casey, abandoned in Dobbs.
Affirmative action - policies designed to remedy past discrimination by considering race or other protected categories in admissions or hiring; ended in university admissions by SFFA v Harvard (2023).
Voting Rights Act 1965 - statute banning literacy tests and requiring federal preclearance for voting changes in covered jurisdictions; preclearance struck down in Shelby County v Holder (2013).
Citizens United v FEC (2010) - case holding that corporate and union political spending is protected speech under the First Amendment.
Originalism - the approach to constitutional interpretation that seeks the original public meaning of the text; associated with Scalia and the contemporary conservative majority.
Living Constitution - the rival approach that reads the Constitution as adapting to modern conditions; associated with the Warren Court and contemporary liberal justices.
Federalist Society - the conservative legal organisation founded in 1982 that built the talent pipeline behind the contemporary conservative majority.
NAACP Legal Defense Fund - the litigation arm associated with the campaign that produced Brown v Board.
ACLU - the American Civil Liberties Union; founded 1920; defends individual rights across ideological lines.
