Unanimously ruled school segregation unconstitutional, overturning Plessy v Ferguson's separate-but-equal doctrine. Enforcement took a decade and federal force; the Civil Rights Act 1964 finished what the Court had started - the classic case study in the limits of Court power without the elected branches.
Brown v Board of Education (1954) ruled unanimously that "separate educational facilities are inherently unequal", dismantling the legal basis for school segregation and opening the modern rights era.
In an essay, Brown is the case the affirmative side of any rights-protection question is built on - pair it with Loving v Virginia (1967) to show the Equal Protection Clause at its boldest.
Plessy v Ferguson (1896) had upheld "separate but equal" segregation for six decades; Brown overturned it outright. The Court at its best moved by breaking its own precedent, which complicates any simple claim that respecting stare decisis is what good courts do.
Use this against the Roberts Court comparison: Brown shows that overturning precedent is not automatically wrong - the question is which way the law moves.
Congress in 1954 could not have passed an anti-segregation statute, and no president could have ordered desegregation alone. The Warren Court named a right the political process would not - the textbook definition of judicial activism.
This is the strongest evidence that activism has no fixed political direction: the same label covers Brown and Dobbs.
Brown imposed a national constitutional standard on state school systems, and enforcement followed the same line: Eisenhower sent federal troops to Little Rock in 1957 to enforce the ruling against state resistance.
Pair this cell with the civil-rights-era row on the federalism grid - the same story from the other side.
Brown named the right but could not enforce it: Brown II (1955) ordered desegregation only "with all deliberate speed", and most Southern schools stayed segregated for a decade. It took Little Rock in 1957 and the Civil Rights Act 1964 to finish the job.
This is the key limit case: the Court can declare, but enforcement depends on the elected branches.
Brown stands untouched after seventy years - no serious legal or political movement seeks its reversal, which makes it the benchmark against which the durability of every other ruling is measured.
Contrast with Roe, which fell after 49 years: durability is not guaranteed by importance.
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, and Brown anchors the racial-equality theme.
Open the rights-protection essay with Brown, then trace the same Equal Protection Clause forward to SFFA (2023) - same text, opposite direction.
Found a constitutional right to abortion in the right to privacy. For 49 years the textbook example of a Court-created right - then Dobbs overturned it in 2022. Roe now does double duty in essays: rights extension and the fragility of Court-made rights in one case.
Roe v Wade (1973) found a constitutional right to abortion in the right to privacy implied by the Fourteenth Amendment's Due Process Clause, setting a trimester framework that bound all fifty states.
It sits in the same Due Process line as Lawrence v Texas (2003) and Obergefell (2015) - the personal-autonomy strand of the rights story.
The right Roe recognised appears nowhere in the constitutional text - it rests on substantive due process, and critics contested that reading from the day it was decided. Planned Parenthood v Casey (1992) reaffirmed Roe explicitly on stare decisis grounds, which made the 2022 reversal a double break.
Roe is the case both sides of the activism debate reach for: the Court created a national right where Congress had not legislated and most state legislatures had not moved. Fifty years of political conflict followed precisely because the right came from the bench rather than the ballot.
Roe's trimester framework constrained the abortion law of every state simultaneously - a single ruling replacing fifty separate state settlements with one national standard.
That is why Dobbs is best taught as a federalism case as much as a rights case: removing the right meant returning the question to the states.
Because Roe rested on the Constitution itself, no statute could undo it - states could only regulate at the margins, and Congress had no route around it. The only answers were amendment, which never came close, or a later Court, which is what eventually happened in 2022.
This is the US-UK contrast in one cell: no Safety of Rwanda Act is possible against a constitutional ruling.
Dobbs v Jackson (2022) overturned Roe and Casey together - 6-3 on the judgment, 5-4 on the overruling itself - holding there is no constitutional right to abortion because it is not "deeply rooted in this Nation's history and tradition". Within a year more than a third of US states had banned or severely restricted abortion.
Roe does double duty in any essay: it is the strongest evidence that the Court can extend rights ahead of the political process, and its fall is the strongest evidence that Court-made rights depend on the Court's composition.
The 2025 examiner report flagged chronological confusion as a common error - keep the order straight: Roe 1973, Casey 1992, Dobbs 2022.
Struck down the Voting Rights Act 1965's coverage formula, disabling Section 5 preclearance. Congress could write a new formula by ordinary statute and has not. Section 2 was further weakened by Louisiana v Callais (2026).
Shelby County v Holder (2013) struck down the Voting Rights Act 1965's Section 4(b) coverage formula, which killed Section 5 preclearance - the requirement that jurisdictions with discriminatory histories clear voting changes with Washington first.
Brnovich (2021) then narrowed Section 2, and Louisiana v Callais (2026) reinterpreted it to require something close to proof of intentional discrimination.
Chief Justice Roberts argued the coverage formula rested on outdated conditions; critics replied that the conditions were outdated only because the law had worked. The Court had repeatedly upheld the VRA's preclearance regime before 2013, so Shelby was a departure from its own settled treatment of the statute.
Striking down the enforcement engine of the most effective civil rights statute in American history is the Court moving the law, whatever language of restraint accompanied it. The follow-through confirms the direction: Brnovich (2021), then Callais (2026), with Allen v Milligan (2023) a brief exception now overtaken.
Preclearance was federal supervision of state election law; ending it returned control of voting rules to the previously covered states, most of them in the South. The civil-rights-era settlement - federal supremacy over state voting practice - was partly unwound by a single ruling.
Shelby struck down the formula, not the principle, so Congress could restore preclearance by writing a new formula in an ordinary statute. The John Lewis Voting Rights Advancement Act would do exactly that - and it has been blocked in the Senate by the filibuster ever since.
This cell is the best single example of the elected branches declining to answer a ruling they could answer.
Shelby stands, and the trajectory has hardened: Louisiana v Callais (29 April 2026) reinterpreted Section 2 to impose liability only where intentional discrimination can be strongly inferred, reversing the discriminatory-effects framework that had governed since Thornburg v Gingles (1986). Kagan in dissent called Section 2 "all but a dead letter".
For any protection-of-rights essay, Shelby is the voting-rights anchor: three rulings of the same Court over thirteen years - Shelby, Brnovich, Callais - have hollowed out the Voting Rights Act in practice.
Pair it with the confirmation row on the Congress grid: the 6-3 majority that completed the job was itself the product of Garland 2016 and Barrett 2020.
Required all states to license and recognise same-sex marriage under the 14th Amendment. The last major rights extension before the Court's composition shifted - and post-Dobbs, the question of its durability is itself exam material.
Obergefell v Hodges (2015) found a constitutional right to same-sex marriage in the Due Process and Equal Protection Clauses of the Fourteenth Amendment, by a 5-4 majority, requiring every state to license and recognise it.
It is the high-water mark of the expansion era - and it came before Dobbs, not after, an ordering the 2025 examiner report singled out as a common error.
No previous Court had found a marriage right for same-sex couples; Obergefell extended the Loving v Virginia (1967) marriage line into territory the precedents had not reached. Like Roe, the right rests on substantive due process - which is exactly why Justice Thomas's Dobbs concurrence questioned its constitutional basis.
Marriage equality had only just achieved majority public approval in 2015, and many state legislatures had not moved. The Court named the right ahead of the political process - the same pattern as Loving in 1967, when a majority of Americans still opposed interracial marriage.
Obergefell replaced a patchwork of state marriage laws with a single national standard under the Fourteenth Amendment - the incorporation logic that makes the Bill of Rights and its extensions run against state governments.
For the Section B comparison: the UK has no equivalent mechanism - a UK court can declare a statute incompatible with rights but cannot impose a new national standard, which is why UK rights change runs through Parliament.
No statute can override a constitutional marriage right, so the elected branches could only reinforce it - which Congress did: the Respect for Marriage Act 2022 codified federal recognition of same-sex marriage after the Dobbs concurrence threatened Obergefell.
That statute is the best evidence for the argument that Congress, not the Court, is the durable defender.
Obergefell stands, but Dobbs changed its risk profile: Justice Thomas's concurrence questioned the constitutional basis of the same-sex marriage and contraception rulings on the same substantive due process logic Dobbs rejected. The Respect for Marriage Act 2022 now provides a statutory backstop.
Obergefell carries two essay jobs: the most recent major rights extension, and the live test of durability after Dobbs. Decades of marriage equality activism preceded it - use it to show that Court victories rest on movement groundwork, not the bench alone.
Overturned Roe and Casey, explicitly invoking the 10th Amendment to return abortion to the states. The states answered instantly in both directions - protection in California and New York, bans in Texas and Alabama - making abortion the textbook live federalism case.
Dobbs v Jackson Women's Health (2022) ruled that no constitutional right to abortion exists - 6-3 on the judgment, 5-4 on overturning Roe (1973) and Casey (1992). Within a year more than a third of US states had banned or severely restricted abortion access.
It is the strongest contemporary evidence that the Court can take rights away as well as deliver them - set it against Brown for the rights-extended-against-rights-removed contrast in one paragraph.
Dobbs overturned two precedents at once - Roe, and Casey, which had reaffirmed Roe explicitly on stare decisis grounds in 1992. Abandoning a precedent that was itself a precedent about keeping precedent is the sharpest break with stare decisis in the modern era.
The majority framed Dobbs as restraint - returning a question the Constitution never settled to the people's representatives. But reversing half a century of settled law and reshaping the rights of every state's residents is the Court moving the law by any neutral test. Each wing calls its own moves restraint; the grid scores the movement.
Justice Alito's majority opinion explicitly invoked the 10th Amendment: where the Constitution does not protect a specific right, regulation is reserved to the states. The result is abortion legal in California and illegal in Alabama within the same federal Union.
This is why Dobbs appears on both this grid and the federalism grid - it is the bridge case.
The states answered instantly and in both directions: California, New York and Illinois protected or expanded access; Texas, Alabama and Tennessee imposed near-total bans; another 15-20 states partially restricted. Idaho's near-total ban produced the medical-emergency case Moyle v United States (2024).
Dobbs stands and defines the current Court: with Bruen (2022) and SFFA (2023) delivered in quick succession, it is the centrepiece of the retrenchment the 6-3 majority has produced since Barrett's 2020 confirmation.
Comparison hook: no UK court could remove a right this way, because UK rights rest on statute and the Human Rights Act, not on judicial readings of an entrenched constitution - the strike-down power against the declaration of incompatibility.
Dobbs is the single most useful case on the grid because it works in three essays at once: rights protection (a right removed), judicial power (precedent overturned), and federalism (the question returned to the states).
The 2025 examiner report singled out Dobbs as a key contemporary example - name it, date it, and say which kind of right it affected.
Struck down race-conscious university admissions, departing from Grutter. With Dobbs and Shelby County it completes the pattern essays need: the modern Court unwinding the rights settlements of the previous half-century.
Students for Fair Admissions v Harvard (2023) struck down race-conscious university admissions under the Equal Protection Clause - the same clause that produced Brown. A clause written to protect newly freed Black citizens, now used against race-conscious remedies: the Fourteenth Amendment cutting both ways in a single case.
SFFA departed from Grutter's affirmative-action settlement, which had allowed race-conscious admissions for two decades. With Dobbs overturning Roe and Casey, and Shelby disabling the VRA, it completes the Roberts Court's pattern of unwinding major precedents.
Decades of admissions practice across American higher education rested on the Grutter settlement; SFFA ended it nationally in one ruling. Whatever the framing, that is the Court moving the law against established practice - activism by the same test that makes Brown activist.
SFFA imposed a single national rule on university admissions everywhere - no state may authorise what the Equal Protection Clause, as now read, forbids. Unlike Dobbs, which devolved, SFFA nationalised: the Roberts Court moves the federal-state line in whichever direction the ruling requires.
Because SFFA rests on the Equal Protection Clause itself, there is no statutory route around it - Congress cannot legislate race-conscious admissions back into existence. Only amendment or a later Court could reverse it, the same closed loop as every constitutional ruling.
The UK pair on the Supreme Court grid is the Safety of Rwanda Act 2024: Parliament overrode a court finding by ordinary statute, the move that is constitutionally impossible against SFFA.
SFFA stands, and the same Equal Protection logic was extended in Louisiana v Callais (2026), which struck down a majority-Black district drawn to remedy historical vote dilution as a racial gerrymander. The doctrine is consolidating, not retreating.
Affirmative action is one of the named thematic frames in the 2025 examiner report, and SFFA is its current endpoint. Use it with Dobbs and Shelby to make the retrenchment argument - and with Brown to show the same constitutional clause producing opposite outcomes across seventy years.
