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 84 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
““Where to draw the precise line between the cases is which the vendor’s knowledge of the purchaser’s intent to make an unlawful use of the goods will vitiate the contract, and those in which it will not, may be difficult. Perhaps it cannot be done by exact definition. The whole doctrine of avoiding contracts for illegality and immorality is. founded on public policy. It is certainly contrary to public policy to give the aid of the courts to a vendor who knew that his goods were purchased, or to a lender who knew that his money was borrowed, for the purpose of being employed in the commission of a criminal act, injurious to society or to any of its members.””
