The Role of Courts in Elections

Referees of Democracy

Courts play a critical role in elections: interpreting election laws, adjudicating disputes over results, striking down unconstitutional restrictions on voting, and resolving challenges to redistricting maps. In many countries, specialized election tribunals or constitutional courts handle these matters. Mexico's Electoral Tribunal, Brazil's Superior Electoral Court, and Kenya's Supreme Court all have jurisdiction over presidential election disputes.

The most famous judicial intervention in an election is Bush v. Gore (2000), in which the US Supreme Court halted a recount in Florida, effectively deciding the presidential election. The 5-4 decision remains deeply controversial. Courts have also played decisive roles in Kenya (2017, where the Supreme Court annulled the presidential election due to irregularities) and Austria (2016, where the constitutional court ordered a re-run of the presidential election due to procedural errors in mail-in ballot handling).

Protecting and Restricting Rights

Courts can both expand and restrict voting rights. In the US, courts have struck down racial gerrymandering, invalidated discriminatory voter ID laws (as in North Carolina, where a federal court found the legislature had targeted Black voters 'with almost surgical precision'), and expanded access to mail-in voting. But courts have also upheld restrictive laws, as when the Supreme Court upheld Indiana's strict voter ID law in Crawford v. Marion County (2008).

The political composition of courts matters enormously. Judicial appointments are increasingly contested precisely because of courts' power over election rules. A court that views voting primarily through a security lens will uphold restrictions; one that views voting primarily as a right will strike them down. The same law can be constitutional or unconstitutional depending on which judges hear the case.

Worked Example: Landmark Election Cases

The US Supreme Court's voting-rights jurisprudence has swung between expanding and contracting access. The table below tracks pivotal decisions and what each changed.

Reading the Shelby County ripple effect

Before 2013, Section 5 of the Voting Rights Act of 1965 required certain jurisdictions with histories of discrimination to get federal 'preclearance' before changing election rules. In Shelby County v. Holder, the Court held the coverage formula in Section 4(b) unconstitutional as outdated, which disabled preclearance in practice. Within days and months, several states moved to implement stricter voter ID laws and other changes that preclearance had previously blocked. This is the mechanism from the prior section made concrete: one 5-4 ruling shifted the default from 'prove it is non-discriminatory first' to 'challenge it in court after the fact,' reshaping voting access nationwide.
