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 14 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“The words 'unjust enrichment' concisely state the necessary elements of an equitable action to recover money, property, etc., which 'good conscience' demands should be set over to the appellee by appellants pursuant to an implied contract between them.”
5 later decisions quote this exact passage“The phrase 'unjust enrichment' is used in law to characterize the result or effect of a failure to make restitution of, or for, property or benefits received under such cireumstances as to give rise to a legal or equitable obligation to account therefor. It is a general principle, underlying various legal doctrines and remedies, that one person should not be permitted unjustly to enrich himself at the expense of another, but should be required to make restitution of or for property or benefits received, retained, or appropriated, where it is just and equitable that such restitution be made, and where such action involves no violation or frustration of law or opposition to public policy, either directly or indirectly.”
3 later decisions quote this exact passage“We have long recognized that an action for money had and received “is an equitable action, and no recovery can be had except upon proof that the defendant has received money of the plaintiff which, in equity and good conscience, it ought not to retain. That is the basis and foundation of the action.” Carton v. Board of County Commissioners of Uinta County, 10 Wyo. 416, 435 , 69 P. 1013 (1902). We have also recognized that an element of fraud or tortious conduct on the part of the defendant is not necessary in an action for “unjust enrichment.” [[Image here]] The words “unjust enrichment” concisely state the necessary elements of an equitable action to recover money, property, etc., which “good conscience” demands should be set over to the appellee by appellants pursuant to an implied contract between them.”
