Calder v. Wife
The Court upheld a Connecticut legislative resolution granting a new trial in an inheritance dispute, ruling that the Constitution's ban on ex post facto laws applies only to criminal laws, not to civil matters like this one.
The decision drew one of the earliest lines around the ex post facto clause, establishing that it protects people only from being punished for conduct that was legal when they did it, not from legislatures adjusting civil rights or procedures retroactively.
How it got here: The Connecticut Supreme Court of Errors upheld the legislature's resolution granting a new probate trial, and the losing party sought review from the U.S. Supreme Court.
The Case in Depth
What happened
A Connecticut probate court denied a will, but the state legislature passed a resolution setting aside that decree and granting a new hearing, which then approved the will and awarded the estate differently. The people who would have inherited under the original ruling challenged the legislature's resolution as an unconstitutional retroactive law that stripped them of vested property rights.
The question before the Court
Did a Connecticut law letting the legislature order a new trial in a probate dispute count as an unconstitutional "ex post facto" law?
Why it matters
The ruling meant state legislatures could pass laws affecting civil rights and property retroactively without running afoul of the Constitution's ex post facto ban, so long as they didn't criminally punish past conduct. This distinction between civil and criminal retroactive laws has shaped how courts evaluate legislative actions affecting property, contracts, and legal procedures ever since.
What changes now
This was a final decision resolving the underlying inheritance dispute in favor of the party who benefited from the new probate hearing. The ruling's lasting significance was doctrinal: it fixed the meaning of the ex post facto clause as applying only to criminal laws, a distinction that later courts would continue to apply when evaluating retroactive legislation affecting civil rights and property.
What this does not decide
The opinions do not decide whether retroactive civil laws are always fair or wise -- several justices personally criticized retroactive lawmaking -- only that such laws, however troubling, are not barred by the specific constitutional ban on ex post facto laws, which is limited to criminal punishment.
Concurrences and dissents
Concurrence — Justice Iredell
“the true conftrudlion of the prohibition extends to criminal, not to civil, cafes.”Iredell's statement that the ex post facto ban applies only to criminal laws, not civil disputes.
Justice Iredell agreed the judgment should be affirmed but for different reasons. He argued that Connecticut's legislature had long exercised genuine judicial power over its courts by custom, making the new-trial resolution a judicial act outside the ex post facto clause entirely. He also separately reasoned that even if it were legislative, courts cannot strike down laws merely for conflicting with abstract natural justice -- only for exceeding constitutional limits -- and the ex post facto ban covers only criminal, not civil, laws.
Concurrence — Justice Cushing
Justice Cushing wrote a brief opinion agreeing the case was straightforward either way: if the legislature's act was judicial, the federal Constitution's ex post facto ban did not touch it, and if it was legislative, it was justified by Connecticut's longstanding practice.
How the Court got there
The legal reasoning, step by step
- The Court first considered whether Connecticut's legislature was acting as a court when it granted the new trial, since Connecticut's unwritten constitution, built on longstanding custom, had allowed the legislature to exercise judicial power alongside ordinary courts since its founding.
- If the legislature's resolution was really a judicial act rather than a legislative one, the constitutional ban on ex post facto laws (laws passed after an act that change its legal consequences) would not apply at all, since that ban restricts only legislative power.
- Even treating the resolution as a legislative act, the Court held that the ex post facto clause has a narrow, technical meaning drawn from long legal tradition: it forbids only laws that criminally punish conduct that was legal when it occurred, or that increase punishment for past crimes.
- The Court supported this narrow reading by noting that the Constitution separately bans laws 'impairing the obligation of contracts,' which would be unnecessary if the ex post facto ban already covered civil laws affecting property and contracts.
- Because the dispute here was purely civil -- about who should inherit an estate -- and involved no criminal punishment, the Court concluded the ex post facto clause simply did not apply, regardless of whether the legislature's action was judicial or legislative in nature.
