Opinion of the Court by Justice O'Connor

The Supreme Court ruled that lower courts went too far by throwing out New Hampshire's entire parental-notification abortion law just because it lacked an explicit health exception for medical emergencies.

Instead of scrapping the whole statute, the Court said judges should first consider narrower fixes — like blocking only the law's unconstitutional applications — and sent the case back for the lower courts to figure out whether New Hampshire's lawmakers would have wanted the rest of the law to survive.

We do not revisit our abortion precedents today, but rather address a question of remedy
Justice O'Connor

O'Connor frames the case as being about the proper judicial remedy, not abortion rights themselves.

How it got here: A federal trial court struck down the law entirely and permanently blocked it; the First Circuit affirmed; New Hampshire asked the Supreme Court to review the remedy.

The Case in Depth

What happened

New Hampshire's Parental Notification Prior to Abortion Act required doctors to wait 48 hours after notifying a minor's parent before performing an abortion, with a judicial-bypass option and a narrow exception for life-threatening emergencies but none explicitly for other serious health emergencies. A doctor and several clinics that provide abortions to minors sued, arguing the law endangered minors' health because it did not clearly allow prompt emergency abortions.

The question before the Court

If enforcing New Hampshire's parental-notification abortion law could endanger a minor's health in rare medical emergencies, did courts have to strike down the entire law?

The Court's answer

No — the Court ruled that lower courts should not have invalidated New Hampshire's entire parental-notification law just because it lacked an explicit health exception for rare medical emergencies. Since only a narrow slice of the law's applications caused a constitutional problem, courts should first consider more targeted relief, like blocking just the unconstitutional applications, rather than wiping out the whole statute.

Because it wasn't clear whether New Hampshire's legislature would have preferred a trimmed-down law to no law at all, the Court sent the case back to the lower courts to sort that out. The ruling leaves open whether the law ultimately survives in some form, and if it does, the lower courts still need to address a separate challenge to the judicial-bypass process's confidentiality rules.

Why it matters

The decision changes how courts respond when an abortion regulation has a constitutional gap: rather than automatically voiding the whole law, courts must consider more limited relief that preserves as much of the legislature's work as possible. This affects how future abortion-related laws — and their emergency exceptions — get challenged and fixed in court.

What changes now

The case returns to the lower courts to decide whether New Hampshire's legislature would have wanted the parental-notification law to remain in effect (minus its unconstitutional emergency applications) or preferred no law at all, given the law's severability clause. If the law survives in part, the Court of Appeals must also address a separate, previously unresolved challenge to the confidentiality of the judicial-bypass process. This is a final ruling on the remedy question but leaves the ultimate outcome for the lower courts to determine.

What this does not decide

The Court did not decide whether New Hampshire's parental-notification law is ultimately valid, whether its life exception is unconstitutionally vague, or how the law's confidentiality provisions should be judged. It also did not disturb the underlying rule that abortion restrictions must not endanger a woman's life or health.

How the Court got there

The legal reasoning, step by step

  1. The Court reaffirmed that states may require parental involvement in a minor's abortion decision and that a law restricting abortion access cannot be applied in ways that endanger a woman's life or health, but treated this case as being about remedy rather than about revisiting those substantive rules.
  2. The Court explained three guiding principles for choosing a remedy: courts should nullify as little of a legislature's work as necessary, courts should avoid essentially rewriting a statute themselves even while fixing constitutional flaws, and any remedy must respect what the legislature would have wanted — asking whether lawmakers would prefer the trimmed-down law to no law at all.
  3. Applying these principles, the Court found that only a few applications of the law — those covering rare medical emergencies — posed a constitutional problem, so invalidating the entire statute was broader than necessary to fix that specific flaw.
  4. The Court distinguished this case from Stenberg v. Carhart, where it struck down an entire abortion law for lacking a health exception, noting that in Stenberg the parties never asked for a narrower remedy, whereas here the challengers themselves suggested that a more targeted injunction could resolve the case.
  5. Because it was unclear whether the New Hampshire legislature intended the law to survive with only its unconstitutional applications blocked, or preferred no law at all if it could not operate as written, the Court concluded that this question of legislative intent should be resolved by the lower courts in the first instance.

Doctrinal impact

Laws and provisions at issue

New Hampshire Parental Notification Prior to Abortion Act

State law requiring doctors to notify a minor's parent 48 hours before an abortion, with limited exceptions.

Fourteenth Amendment

Constitutional provision underlying the requirement that abortion laws not endanger a woman's health or life.

Cases affected by this decision

Distinguishes Stenberg v. Carhart (530 U.S. 914)

The Court said this case differs because no one there asked for a narrower remedy than striking down the whole law.

Reaffirms Casey (505 U.S. 833)

The Court relied on Casey's rule that abortion restrictions cannot endanger a woman's life or health.
