The Role of the Supreme Court in Voting Rights

The Supreme Court of the United States holds the ultimate authority to interpret the Constitution and federal laws that govern elections. Its decisions can either safeguard or restrict the ability of citizens to vote. The Court reviews cases that challenge voting laws at the state and federal levels, often ruling on issues such as voter identification requirements, redistricting, and access to the ballot box. Understanding the Court’s influence helps voters anticipate changes to their rights and prepare for each election cycle.

Landmark Cases That Shaped Voting Rights

Several Supreme Court rulings have fundamentally altered the landscape of voting rights. In Shelby County v. Holder (2013), the Court struck down a key provision of the Voting Rights Act that required jurisdictions with a history of discrimination to obtain federal approval before changing voting laws. This decision opened the door for states to enact stricter voter ID laws, close polling places, and purge voter rolls without prior oversight. Another critical case, Rucho v. Common Cause (2019), held that partisan gerrymandering is a political question not subject to federal court review, effectively allowing state legislatures to draw districts that favor their party. More recently, in Brnovich v. Democratic National Committee (2021), the Court upheld Arizona voting restrictions that limited ballot collection and out-of-precinct voting, making it harder for some voters to cast ballots. These rulings show how the Supreme Court can shape the rules of democracy for decades.

The Court’s Current Stance and Upcoming Cases

As of 2025, the Court’s conservative majority continues to signal skepticism toward broad federal protections for voting rights. Cases on the docket often involve challenges to state laws that tighten voting procedures, such as requirements for proof of citizenship or restrictions on mail-in ballots. For voters, tracking these developments is essential because the outcomes can affect access to the polls. Organizations such as the Brennan Center for Justice provide regular updates on litigation that may reach the Supreme Court.

Key Voting Rights Protections

Several constitutional amendments and federal statutes form the backbone of voting rights in the United States. These protections aim to eliminate discrimination and ensure that every eligible citizen can participate in elections.

The Voting Rights Act of 1965

The Voting Rights Act (VRA) is widely considered the most effective civil rights legislation ever enacted. It banned racial discrimination in voting, prohibited literacy tests, and required federal oversight of jurisdictions with a history of discriminatory practices. Although the Shelby County decision weakened Section 5, other parts of the VRA remain in effect. For example, Section 2 still allows private lawsuits against discriminatory voting practices. The Act has been used to challenge voter ID laws, redistricting plans, and other measures that disproportionately affect minority voters. Learn more about the VRA from the ACLU’s voting rights page.

The 15th, 19th, and 26th Amendments

  • The 15th Amendment (1870) prohibits the denial of voting rights based on race, color, or previous condition of servitude. It laid the foundation for later civil rights laws.
  • The 19th Amendment (1920) secured the right to vote for women, removing gender-based barriers to the ballot box.
  • The 26th Amendment (1971) lowered the voting age to 18, ensuring that young adults could vote in elections that affected their lives.

These amendments remain powerful tools for challenging laws that discriminate based on race, gender, or age. However, their effectiveness depends on enforcement by the courts and Congress.

Your Core Voting Rights as a Citizen

Every voter should know the specific protections they have under federal law. These rights apply regardless of the state in which you vote, though implementation can vary.

The Right to Vote Without Discrimination

You cannot be denied the right to vote based on race, color, ethnicity, or gender. Poll workers must not treat you differently because of who you are. If you believe you have been discriminated against, you can file a complaint with the U.S. Department of Justice or a civil rights organization.

The Right to Cast a Provisional Ballot

If a poll worker cannot confirm your registration, you have the right to vote a provisional ballot. This ensures your vote is counted after officials verify your eligibility. Keep the receipt provided and check with your local election office to confirm your ballot was counted.

The Right to Assistance and Accessibility

Voters with disabilities have the right to accessible polling places and voting machines. If you need help due to a disability or language barrier, you can bring a person to assist you (or request assistance from a poll worker). Federal law requires that all polling places comply with the Americans with Disabilities Act. For more details, visit the Election Assistance Commission’s guide for voters with disabilities.

The Right to a Private, Intimidation-Free Vote

Intimidation at the polls is illegal. You have the right to cast your ballot without being threatened, harassed, or coerced. If you feel unsafe, report the incident immediately to a poll worker or election judge. Organizations like the League of Women Voters offer resources on what to do if you face intimidation.

Current Challenges to Voting Rights

Despite these protections, voters face ongoing challenges that can suppress turnout. Awareness of these issues is the first step in combating them.

Voter ID Laws

Many states have enacted strict voter identification requirements that require specific types of photo ID. While supporters argue they prevent fraud, critics point out that such laws disproportionately affect low-income voters, minorities, and the elderly who may lack the required ID. Some states offer free IDs, but the process to obtain them can be burdensome. The Supreme Court has generally upheld these laws as constitutional, subject to certain limitations. Voters should check their state’s ID requirements well before election day.

Gerrymandering

Partisan gerrymandering involves drawing district boundaries to favor one political party. The Court’s decision in Rucho v. Common Cause effectively removed federal judicial oversight of this practice, leaving states to police themselves. Some states have created independent redistricting commissions to reduce bias, but many have not. Gerrymandering can dilute the voting power of minority communities and make elections less competitive. Advocacy groups continue to push for state-level reforms.

Voter Purges

Voter purges remove names from registration rolls, often targeting voters who have not participated in recent elections or whose addresses have changed. While removing ineligible voters is necessary, aggressive purges can remove eligible voters in error. The Supreme Court has allowed states to purge rolls based on limited activity, but voters must be given notice and an opportunity to correct errors. It is wise to check your registration status periodically, especially before primary elections. You can do so through your state’s election website or via CanIVote.org.

What to Do if Your Voting Rights Are Violated

Knowing your rights is only part of the equation. You must also know how to act if those rights are violated.

Filing a Complaint

If you experience discrimination, intimidation, or other violations at the polls, document what happened, gather the names of witnesses, and note the time and location. Then file a complaint with your state election office and the Voting Section of the Civil Rights Division of the U.S. Department of Justice. You can also contact nonpartisan organizations such as the ACLU or the Lawyers' Committee for Civil Rights Under Law for assistance.

If your complaint is not resolved, you may need to consult an attorney who specializes in voting rights. Many legal aid clinics offer free or low-cost representation for such cases. The Election Protection Coalition, a national nonpartisan effort, runs a hotline where you can get real-time help on election day. Remember, the legal system can be slow, but taking action helps protect not only your vote but the votes of others in your community.

Conclusion: The Power of an Informed Voter

The Supreme Court plays a decisive role in shaping the rules of democracy, but every voter also has a role to play. By understanding landmark rulings, recognizing current threats to voting access, and knowing how to defend your rights, you become a stronger participant in the democratic process. Stay informed, check your registration, and encourage others to do the same. Your voice matters most when it is backed by knowledge and action.
