Rivera v. Minnich

Background

An unmarried mother, Jean Marie Minnich, filed a child support suit three weeks after giving birth, naming Gregory Rivera as the alleged father. Rivera asked the trial court to require clear and convincing proof of paternity, but the jury used the usual civil standard, preponderance of the evidence, and found him to be the father. Pennsylvania's Supreme Court reinstated that verdict after a new-trial order. The question reached the United States Supreme Court: does using the lower civil proof standard to establish paternity violate the Fourteenth Amendment's Due Process Clause?

Reasoning

The majority, led by Justice Stevens, answered no and affirmed the state court. The Court relied on two main points: most States treat paternity suits as civil actions and commonly use the preponderance standard, and paternity cases differ materially from proceedings that permanently end parental rights. Creating a legal obligation to support a child does not destroy a prior right in the way termination does, and the mother and alleged father share roughly equal private interests in the outcome, so sharing the ordinary risk of error is reasonable.

Real world impact

The decision lets states continue using the ordinary civil proof level in paternity suits, making it relatively easier for mothers and child-support systems to establish legal fatherhood. It does not alter the higher proof requirement for terminating parental rights, which remains governed by earlier decisions.

Dissents or concurrances

Justice O'Connor concurred in the judgment but not the opinion, offering a different rationale. Justice Brennan dissented, arguing paternity imposes lifelong financial and moral duties and should require clearer proof.
