Supreme Court of the United States, Wheaton v. Peters — Argument of Mr Ingersoll…
“ It cannot be contended, with any semblance of justice, that the mere opinions of the judges, communicated to Mr Wheaton, as it is alleged they were, could be the subject of literary property. A book composed in part of those opinions, and in part of other matters, does not change the nature of the opinions themselves. An individual who thus mingles what cannot be exclusively enjoyed, with what can, does, upon familiar principles, rather forfeit the power over his own peculiar work, than throw the chain around that which is of itself as free as air. ”
