Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work.

““It cannot be said that the public interest is adversely affected if a physician decides to move from one community to another, nor does it become so if the move results from some agreement made in advance. If a severe shortage exists in any particular place young doctors will tend to move there, thus alleviating the shortage.””
