Most people think the legal battle over abortion started and ended with Roe v. Wade. That’s a mistake. If Roe was the earthquake, Planned Parenthood v. Casey was the decades-long aftershock that actually defined how life worked for millions of people until 2022. It’s the case that basically invented the rules we lived by for thirty years.
Before the Supreme Court officially tossed everything out in Dobbs, Casey was the law of the land. It was messy. It was a compromise that almost nobody actually liked, yet it held the country’s legal fabric together by a thread. Honestly, the story of how it happened is wilder than the legal jargon suggests. You had a conservative-leaning court that everyone expected to kill Roe right then and there in 1992. Instead, they blinked. They blinked and created something entirely new called the "undue burden" standard.

The Trio That Saved Roe (Sorta)
In the early 90s, the vibes in the Supreme Court were shifting hard to the right. Republican presidents had been stacking the bench for years. When Planned Parenthood of Southeastern Pennsylvania v. Casey reached the marble steps of the Court, the pro-life movement was ready to pop the champagne. They had the votes. Or so they thought.
Justice Anthony Kennedy, Justice Sandra Day O'Connor, and Justice David Souter did something nobody saw coming. They wrote a joint opinion. It wasn't just a regular ruling; it was a statement on the Court’s own legitimacy. They basically argued that if the Court flips its position every time the political wind blows, people will stop trusting the law.
They kept the "essential holding" of Roe. That means they kept the right to have an abortion before a fetus can survive outside the womb (viability). But they threw away the "trimester framework." Remember that? Roe used to divide pregnancy into three neat boxes. Casey said, "Forget the boxes."
Instead, they gave states the green light to pass more restrictions, as long as those restrictions didn't put a "substantial obstacle in the path of a woman seeking an abortion." That sounds clear, right? It wasn't. It was incredibly vague.

What an Undue Burden Actually Looked Like
For thirty years, lawyers made careers out of arguing over what "substantial" meant. To a billionaire, a $500 fee isn't an obstacle. To a mother of three working two jobs in rural Pennsylvania, that same fee plus a 24-hour waiting period is a brick wall.
Casey allowed states to require:
- A 24-hour waiting period.
- "Informed consent" materials (which often included graphic or biased information).
- Parental consent for minors (with a judicial bypass).
But the Court drew a hard line at one specific thing: spousal notification. Pennsylvania wanted women to have to tell their husbands before getting an abortion. The Court said no. They realized that for women in abusive relationships, "notifying" a husband isn't just a formality—it's a death sentence. It’s one of the few times the ruling felt deeply attuned to the reality of domestic power dynamics.
The impact was immediate. States started testing the fences. They passed "TRAP" laws (Targeted Regulation of Abortion Providers). These were laws that required clinics to have tiny hallways of a specific width or doctors to have admitting privileges at nearby hospitals. Proponents said it was for "safety." Opponents said it was a scam to shut down clinics. Under Casey, the courts had to decide: Is this a safety rule, or is it an undue burden?
The 2026 Perspective: Why Casey Collapsed
Looking back from 2026, the fragility of Casey is glaringly obvious. It was a middle-ground solution in a country that had stopped looking for middle ground. When the Dobbs v. Jackson decision came down in 2022, the justices didn't just target Roe; they took a sledgehammer to Casey.
Justice Samuel Alito’s majority opinion argued that Casey’s "undue burden" test was unworkable. He wasn't entirely wrong about the "unworkable" part—judges across the country were reaching completely different conclusions using the same test. One judge in Texas would see a law as fine, while a judge in California would see it as a violation.
The fallout of Casey's demise has been a total balkanization of American healthcare. We've moved from a world where "undue burden" was the debate to a world where "geography is destiny."
Real World Consequences
Let’s talk about the 24-hour wait. In the Casey era, if you lived in a state with only one clinic, you had to drive there, get the "counseling," find a hotel, stay the night, and then get the procedure the next day. That meant two days off work, childcare costs, and travel expenses. For a lot of people, Casey’s "protection" was already a myth.
The "viability" marker also became a moving target. In 1973, viability was around 28 weeks. By 1992, it was closer to 23 or 24. Today, with advanced NICU technology, that line continues to shift, making the legal logic of Casey feel more like a medical debate than a constitutional one.
Misconceptions You Probably Have
One big myth is that Casey made it easier to get an abortion. It actually did the opposite. While it saved the right to the procedure, it opened the floodgates for states to make it as annoying and expensive as possible. It traded the "privacy" logic of Roe for a "liberty" logic under the Due Process Clause of the 14th Amendment.
Another misconception? That it was a liberal win. Nope. The pro-choice groups at the time were actually pretty devastated. They saw it as the beginning of the end. They realized that by getting rid of the trimester framework, the Court was giving states a "how-to" guide on slowly strangling access.
The Legal Legacy
If you’re trying to understand the current legal landscape, you have to look at the "Reliance Interests" mentioned in the Casey ruling. The 1992 Court argued that people had organized their lives, their careers, and their relationships around the availability of abortion. They argued that you can't just take that away without causing social chaos.
When Dobbs happened, the current Court basically said, "We don't care about those reliance interests." That’s a massive shift in how the Supreme Court functions. It’s not just about abortion; it’s about how much the Court values stability over its own ideological preferences.
What Happens Now?
Since Casey is dead, the legal "gray area" is gone. We are now in a "black and white" era. States either have total bans, or they have wide-open access. The "middle way" that O'Connor and Kennedy tried to build has been demolished.
If you are following the current legal battles, watch the state supreme courts. That’s where the new Caseys are being written. Some states are finding "rights to privacy" in their own state constitutions that mirror the old Casey standards.
Practical Steps for Staying Informed:
- Check State-Specific Statutes: Don't rely on federal news. Look at your specific state's "Trigger Laws" or recent amendments.
- Monitor EMTALA Cases: The big fight right now is between state bans and the federal Emergency Medical Treatment and Labor Act. This is the new frontline.
- Support Legal Literacy: Understand the difference between "statutory rights" (laws passed by Congress) and "constitutional rights" (rights interpreted by the Court). The future of this issue is likely moving toward the former.
The "undue burden" era is over. We’re in the era of "total jurisdiction." Whether that’s a good or bad thing usually depends on which side of a state line you're standing on.
