Parker v. Levy is a seminal decision in military law that I have written about in previous posts. That decision upheld two rather sweeping criminal statutes that criminalize, by way of a conviction in a federal court, any conduct by a military officer or enlisted person that other military officers think is unbecoming of an officer and a gentleman (gentlewoman), or is prejudicial to good order and discipline or otherwise brings discredit to the armed forces. For those trained in the law or eerily erudite in the law absent training, these statutes appear unconstitutionally vague. But in his majority decision, then-Justice Rehnquist wrote that “the proper standard of review for a vagueness challenge to the articles of the Code is the standard which applies to criminal statutes regulating economic affairs. I have since wondered what that meant, and whether this view is worth re-assessing.
