Oliver Wendell Holmes, Jr., Horning v. District of Columbia…
“ In such a case obviously the function of the jury if they do their duty is little more than formal. The judge cannot direct a verdict it is true, and the jury has the power to bring in a verdict in the teeth of both law and facts. But the judge always has the right and duty to tell them what the law is upon this or that state of facts that may be found, and he can do the same none the less when the facts are agreed. If the facts are agreed the judge may state that fact also, and when there is no dispute he may say so although there has been no formal agreement. ”
