Preclearance was the Section 5 Voting Rights Act requirement that jurisdictions with documented histories of racial voting discrimination get Department of Justice or federal court approval before changing any voting law, until Shelby County v. Holder (2013) effectively ended it.
Preclearance flipped the normal legal script. Usually, if a state passes a discriminatory voting law, someone has to sue after the fact. Under Section 5 of the Voting Rights Act of 1965, certain states and counties (mostly in the South, identified by a coverage formula in Section 4) had to ask permission first. Any change to voting procedures, from registration deadlines to polling place locations to new district maps, had to be approved by the Department of Justice or a federal court before it could take effect.
Congress built preclearance as an enforcement tool for the Fifteenth Amendment, which bans racial discrimination in voting. The logic was simple. States had spent decades inventing new barriers (literacy tests, grandfather clauses, poll taxes) faster than courts could strike them down, so preclearance stopped new discrimination before it started instead of cleaning it up afterward. In Shelby County v. Holder (2013), the Supreme Court struck down the coverage formula as outdated, which left preclearance technically on the books but with no jurisdictions covered. Federal oversight of state election rules dropped sharply as a result.
Preclearance lives in Topic 5.1 (Voting Rights and Models of Voting Behavior) in Unit 5: Political Participation. It directly supports learning objective AP Gov 5.1.A, which asks you to describe voting rights protections in both the Constitution and in legislation. Preclearance is the perfect example of how those two layers work together. The 15th Amendment is the constitutional promise, and the Voting Rights Act's preclearance requirement was the legislation that gave the promise teeth. It also feeds the bigger AP Gov themes of federalism and civil rights, because preclearance is one of the clearest cases of the federal government overriding state control of elections, and Shelby County is one of the clearest cases of the Court handing that control back.

Fifteenth Amendment (Unit 5)
The 15th Amendment banned racial discrimination in voting in 1870, but for nearly a century states evaded it with workarounds. Preclearance was Congress finally enforcing that amendment with a real mechanism, which is exactly the Constitution-plus-legislation pairing LO 5.1.A asks you to describe.
Literacy Tests (Unit 5)
Literacy tests show why preclearance existed. States kept inventing new barriers faster than lawsuits could kill them, so the Voting Rights Act banned the old tricks and used preclearance to block any new ones before they took effect.
Gerrymandering (Unit 5)
Redistricting counted as a voting change, so covered states had to preclear new district maps. After Shelby County, those states could redraw maps without federal sign-off, which links preclearance to debates over racial gerrymandering.
Federalism (Unit 1)
Preclearance is a federalism story. The Constitution gives states the main role in running elections, preclearance put the federal government in a supervisory seat, and Shelby County shifted power back toward the states. That tension is a classic AP Gov argument prompt.
Preclearance shows up most often in multiple-choice questions about the Voting Rights Act and Shelby County v. Holder. One common stem asks which provision of the VRA the Court effectively invalidated in 2013, and another gives you a scenario, like a Southern state changing its voter registration deadline after 1965, and asks what the state had to do first under the Act. Your job is to recognize that the answer is federal approval before the change takes effect. No released FRQ has used the term verbatim, but preclearance is strong evidence in any argument essay about federalism, civil rights enforcement, or how the elected branches and the Court interact. Be precise about the timeline. Preclearance operated from 1965 until 2013, and Shelby County is why it no longer functions.
Students often say Shelby County 'struck down preclearance' or 'struck down the Voting Rights Act.' Technically, the Court invalidated Section 4(b), the coverage formula that decided which jurisdictions needed preclearance. Section 5's preclearance requirement survived on paper, but with no formula, no jurisdiction is covered, so preclearance is effectively dead. On a precise MCQ, that distinction can be the whole question.
Preclearance, under Section 5 of the Voting Rights Act of 1965, required jurisdictions with histories of racial voting discrimination to get federal approval before changing any voting law or procedure.
It worked preventively, blocking discriminatory changes before they took effect instead of forcing voters to sue after the damage was done.
Preclearance was Congress's enforcement of the Fifteenth Amendment, making it the go-to example of constitutional and legislative voting protections working together (LO 5.1.A).
Shelby County v. Holder (2013) struck down the coverage formula, which left preclearance unenforceable and significantly reduced federal oversight of state election rules.
Preclearance is a federalism flashpoint, because it placed federal supervisors over a power (running elections) that normally belongs to the states.
Preclearance was the requirement under Section 5 of the Voting Rights Act of 1965 that states and counties with documented histories of racial discrimination in voting get approval from the Department of Justice or a federal court before changing any voting rule. It appears in Topic 5.1 as a legislative protection of voting rights.
No. The 2013 decision struck down the Section 4(b) coverage formula that determined which jurisdictions needed preclearance. The rest of the Voting Rights Act still stands, but without a coverage formula, Section 5 preclearance can't be applied anywhere, so it's effectively dead.
Not in practice. Section 5 is still technically law, but since Shelby County v. Holder (2013) wiped out the formula deciding who is covered, no jurisdiction currently has to seek preclearance. States can change voting laws without advance federal approval.
Banning literacy tests outlawed one specific known barrier. Preclearance was broader and forward-looking, requiring federal review of any new voting change so states couldn't just invent the next barrier. The Voting Rights Act did both.
It's not one of the 15 required cases, but it's fair game in multiple-choice questions about the Voting Rights Act, and it's useful evidence in argument essays about federalism and voting rights. Know that it gutted preclearance in 2013 by invalidating the coverage formula.
