Williams v. Walsh

Background

A Kansas seller of black powder was convicted for selling powder to a miner that was not in an original sealed twelve and one-half pound package as required by a 1907 state law. He was fined and jailed, then challenged the conviction in state court and in habeas corpus, arguing the law denied equal treatment and violated the federal rule governing interstate commerce. The state courts rejected those claims, and the case reached this Court.

Reasoning

The Court first rejected the equal-treatment complaint, saying the legislature could lawfully treat preexisting contracts differently to avoid unlawful retroactive punishment and that the statutory classification was not arbitrary. On the interstate-commerce claim, the Court declined to decide that issue on the merits because the trial record contained no proof the powder had been imported or that the seller was acting for an out-of-state importer, and habeas review cannot supply new evidence. The opinion also emphasized that black powder is a dangerous explosive and that states may regulate hazardous businesses to protect life and property.

Real world impact

The ruling leaves the Kansas conviction intact and affirms a state’s authority to require sealed twelve and one-half pound packages for powder used in coal mines. Sellers who claim an interstate-import defense must present proof at trial; absent such proof, federal review will not create new evidence. Because the Court did not resolve the commerce question on the merits, disputes about clearly imported shipments could appear again in future cases.
