Bigamy has long been criminalized and late in the 19th century the U.S. Supreme Court held that the Constitution’s guaranty of religious freedom did not allow a Mormon to avoid prosecution for bigamy. The decision, Reynolds v. U.S., is here: https://scholar.google.com/scholar_case?case=1104642225155375579 . A decision by the 10th Circuit Court of Appeals dismissed a constitutional challenge to Utah’s anti-bigamy statute on technical grounds rather than relying on — or even mentioning — the nearly 130 year old precedent. https://www.ca10.uscourts.gov/opinions/14/14-4117.pdf . I wonder whether the intersection of religious freedom and rule of law is is becoming less clear.
