For most of American history, people with disabilities were shut out of schools, jobs, public buildings, and even their own communities. That started to change in the 1970s, when activists pushed for new laws and took their fight all the way to the Supreme Court. These landmark disability rights cases and laws reshaped the country, and many of the protections they created are ones we now take for granted.

A Dark Starting Point

It’s hard to understand how far disability rights have come without looking at where they started. In Buck v. Bell in 1927, the Supreme Court upheld a Virginia law allowing the forced sterilization of people the state considered “unfit.” It remains one of the most controversial Supreme Court cases ever decided, and it was never formally overturned.

For decades afterward, many people with disabilities lived in large state institutions, often in terrible conditions. Public schools could legally refuse to educate children with disabilities. Buildings, buses, and sidewalks were designed with no thought for wheelchair users or people who were blind or deaf.

Section 504 and the Sit-In That Made It Real

In 1973, Congress passed the Rehabilitation Act. One short section, Section 504, made it illegal for any program receiving federal money to discriminate against people with disabilities. It was the first federal civil rights protection of its kind.

There was one problem. The government didn’t issue the regulations needed to enforce it, and years went by with nothing happening. In April 1977, disability activists occupied federal offices in several cities, and the protest in San Francisco lasted nearly a month.

Led by organizers including Judy Heumann and Kitty Cone, more than 100 protesters refused to leave the federal building until the rules were signed. They finally were, and the 504 sit-in is still remembered as one of the longest occupations of a federal building in U.S. history. It proved that disability rights activists could force the government to act.

The Right to an Education

In 1975, Congress passed the Education for All Handicapped Children Act, now known as the Individuals with Disabilities Education Act, or IDEA. It guarantees children with disabilities a free, appropriate public education. It also created the individualized education program, or IEP, that millions of families rely on today.

Board of Education v. Rowley (1982)

The first big IDEA case involved Amy Rowley, a deaf student whose parents asked her school to provide a sign language interpreter. The Supreme Court ruled against the family, holding that the law required schools to provide an education with some benefit, not the best possible education. For years, schools treated that as a fairly low bar.

Endrew F. v. Douglas County School District (2017)

Thirty-five years later, the court raised that bar. In a unanimous decision, the justices ruled that a child’s educational program must be designed to help the child make meaningful progress in light of their circumstances. It was a major win for families pushing for more than the bare minimum.

City of Cleburne v. Cleburne Living Center (1985)

A Texas city denied a permit for a group home for adults with intellectual disabilities, even though it would have allowed other group housing on the same property. The Supreme Court struck down the decision, finding that it was based on irrational fears and prejudice. The case made clear that governments can’t single out people with disabilities just because neighbors are uncomfortable.

The Americans with Disabilities Act (1990)

The biggest milestone came in 1990. Before the vote, dozens of activists left their wheelchairs and crutches at the bottom of the U.S. Capitol steps and pulled themselves to the top. That moment, known as the Capitol Crawl, became one of the most powerful images of the movement.

President George H.W. Bush signed the Americans with Disabilities Act on July 26, 1990. The law bans discrimination against people with disabilities in employment, state and local government services, public accommodations like stores and restaurants, transportation, and telecommunications. The Justice Department’s ADA website explains each part of the law and how it applies today.

The ADA is mostly enforced through complaints to federal agencies and civil lawsuits brought by people who face discrimination. It changed the physical landscape of the country, too. Curb cuts, accessible entrances, captioning, and ramps are all part of its legacy.

Olmstead v. L.C. (1999)

Lois Curtis and Elaine Wilson were two women with intellectual disabilities and mental illness who were kept in a Georgia psychiatric hospital long after their doctors said they could live in the community. They sued, arguing that keeping them institutionalized violated the ADA. The case was filed under Curtis’s initials, which is why it’s known as Olmstead v. L.C.

The Supreme Court agreed with them. In an opinion by Justice Ruth Bader Ginsburg, the court held that unjustified isolation of people with disabilities is a form of discrimination. You can read the full Olmstead decision through Cornell Law School’s Legal Information Institute.

Olmstead is often called the most important disability rights case in history. It pushed states to move people out of institutions and into homes and community settings with the support they need. Its effects are still unfolding today.

PGA Tour v. Martin (2001)

Casey Martin was a professional golfer with a circulatory condition that made walking long distances painful and dangerous. The PGA Tour required players to walk the course, and it refused to let him use a golf cart. The Supreme Court ruled that the ADA required the tour to make that accommodation, since using a cart wouldn’t fundamentally change the competition.

Tennessee v. Lane (2004)

George Lane, a wheelchair user, was required to appear in a Tennessee courthouse that had no elevator. At one hearing, he crawled up two flights of stairs to reach the courtroom. When he refused to do it again, he was arrested for failing to appear.

The Supreme Court ruled that Congress had the power to let people like Lane sue states for failing to provide access to the courts. The decision confirmed that the ADA’s protections reach the courthouse doors, which is where access to justice begins. It’s hard to have a fair day in court if you can’t get into the courtroom.

Why These Cases Still Matter

Disability rights law didn’t come from nowhere. It was built by activists who occupied buildings, crawled up steps, and brought cases that forced the country to live up to its own promises. Each ruling on this list moved the line a little further.

The fight isn’t over, either. Questions about accessible technology, employment, and community living are still being argued in courts and legislatures. These landmark cases are the foundation every new argument builds on, much like the other landmark Supreme Court cases that shaped American rights.
