Audita querela

Audita querela (Law Latin for "[the] complaint [having been] heard") is a writ, stemming from English common law, that serves to permit a defendant who has had a judgment rendered against him or her to seek relief of the consequences of such a judgment where there is some new evidence or legal defense that was not previously available. The writ is thus generally used to prevent a judgment from being executed where enforcement of that judgment would be "contrary to justice". At common law, the writ may be useful where a creditor engages in fraud before the judgment is rendered, or because the debt had been discharged, paid or otherwise satisfied after the judgment is rendered.
