Law
Substantive Due Process and the Right to Bodily Autonomy
Quick fact
The Supreme Court first used substantive due process to protect bodily autonomy in 1965, when it struck down a Connecticut law banning contraception. The right was not found in a specific part of the Constitution but in the 'penumbras' of the Bill of Rights.
Why this is interesting
You have a right to decide what happens to your own body—but the Constitution never explicitly says so. How do judges know you have that right?

Understanding Substantive Due Process and the Right to Bodily Autonomy
Substantive due process is a legal doctrine that reads the Due Process Clause of the 14th Amendment as protecting certain fundamental rights from government interference, even if those rights are not explicitly listed in the Constitution. It's a way of saying that some liberties are so essential to a free society that no government can take them away without a very strong reason. Think of it as a shield that courts hold up to protect deeply personal decisions—like whether to use contraceptives, have an abortion, or marry someone of the same sex—from legislative majority. The step-by-step process is: a law is challenged, the court asks if the right is fundamental, and if so, the government must justify the law with a compelling interest and narrowly tailored means.
A deeper explanation
The mechanism of substantive due process is judicial interpretation. The phrase 'substantive' distinguishes it from procedural due process, which is about fair process. It emerged in the early 20th century, famously in Lochner v. New York (1905), where the Court struck down a labor law as violating 'freedom of contract.' Though Lochner was later rejected, the idea of unenumerated rights persisted. In Griswold v. Connecticut (1965), the Court found a right to privacy in the 'penumbras' of the Bill of Rights, and this right was extended to abortion in Roe v. Wade (1973) through the concept of personal autonomy. The Court's reasoning is that certain rights are so rooted in the Nation's history and tradition, or are so fundamental to liberty, that they must be protected from undue government intrusion. When a law infringes on such a right, courts apply strict scrutiny—requiring a compelling state interest and narrow tailoring. In the specific case of abortion, a unique 'undue burden' test was later formulated in Planned Parenthood v. Casey (1992), asking whether a regulation has the purpose or effect of placing a substantial obstacle in the path of a woman seeking an abortion. This doctrine is controversial because it allows judges to find rights not written in the text, and the Supreme Court's recent decision in Dobbs v. Jackson Women's Health Organization (2022) overturned Roe and returned the issue to the states, showing that the doctrine's scope is not fixed. Understanding this mechanism is essential because it explains how constitutional rights evolve and how courts balance individual liberty against state interests.
