What if there was a federal law stating that anytime you owe anyone a duty to be honest and you violate that duty, you’re committing a federal felony? Guess what—there already is. And now the Supreme Court is deciding whether to strike it down.
There’s a federal law on the books called “honest services fraud,” making it a crime to deprive anyone of the “intangible right of honest services.” In other words, if you’re in a relationship where you have a duty to provide a service to someone (government, employer, etc.), and you engage in any sort of deceit resulting in them not getting your honest, good-faith efforts, then you’ve committed a felony that could land you in federal prison for twenty years.
