"Ordinarily. it is true that thc.ludgmcnt of a court binds only the partics and their privies in representations or estate. But hc who purchases during the pendencl- of an action, is held bound by thejudgment that may be against thc pcrson from whom he derives title. The Iitigating parties arc exempted from raking any notice of the title so acquired: and such purchaser need not be made a party to the action. Where there is a real and fair purchase uithout any noticc, the rule may operate very hardly, But it is a rule founded upon a great public policy; for otherwise, alienations made during an action might deleat its whole purpose, and thcre would be no end to litigation. And hence arises the maxim pendente lite, nihil innoveturi the effect of which is not to annullhe conveyance, but only to render it subservient to the rights of the parties in the litigation. As to the rights of these panies, the conveyance is treated as if it never had any existence; and it does not vary them.
