Antonin Scalia,
Griffin v. United States — Opinion of the Court
“ In this sense "legal error" occurs when a jury, properly instructed as to the law, convicts on the basis of evidence that no reasonable person could regard as sufficient. But in another sense-a more natural and less artful sense-the term "legal error" means a mistake about the law, as opposed to a mistake concerning the weight or the factual import of the evidence. The answer to petitioner's objection is simply that we are using "legal error" in the latter sense.That surely establishes a clear line that will separate Turner from Yates, and it happens to be a line that makes good sense. ”
