In United States v. Emholt, the United States Supreme Court was asked to decide whether a federal statute that prohibited the sale of liquor within four miles of a military post was constitutional. The defendant, Emholt, had been convicted of selling liquor within four miles of a military post in violation of the statute. Emholt argued that the statute was unconstitutional because it violated the Commerce Clause of the United States Constitution. The Supreme Court held that the statute was constitutional. The Court reasoned that the statute was a valid exercise of Congress’s power to regulate commerce. The Court noted that the statute was intended to protect the military from the “evil influence” of liquor and that it was a reasonable means of doing so. The Court also noted that the statute did not interfere with interstate commerce, as it only applied to sales within four miles of a military post. The Court concluded that the statute was a valid exercise of Congress’s power to regulate commerce and was therefore constitutional. The Court affirmed Emholt’s conviction.

In United States v. Emholt, the Supreme Court was tasked with determining whether a federal statute that allowed for the forfeiture of property used to commit certain offenses applied to an individual who had been convicted in state court and whose conviction had become final before Congress passed the statute. The majority opinion held that it did not apply because there was no evidence that Congress intended for such retroactive application. Justice Field dissented from this decision, arguing that since Congress has broad powers over matters involving interstate commerce and criminal law, they could have reasonably intended their legislation to be applicable even if it affected individuals who were already convicted under state laws prior to its passage. He further argued that allowing such retroactive application would not violate any constitutional rights as long as due process is followed when enforcing these statutes against those previously convicted in state courts.
