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. These counts are smaller than the citation total above because most of the 9 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“Courts have used different approaches in reaching the result that government regulations have an effect on contractual obligations and rights. In some cases the Court has presumed that the parties intended to incorporate existing laws. Some Courts have merely stated the proposition that in the absence of contrary provisions in the contract existing laws are an obligation of the contract with the same effect as if expressly set forth in the contract. Other Courts have held that existing law is an implied term of every contract.... The significance of the above ... is their unanimity that a statute or ordinance which purports to impose a requirement or a restriction on a subject matter which is directly involved in a contract will be given effect in the application and enforcement of the contract unless the contract by clear language removes the contractual undertakings from the effect of the law or ordinance.”
