Referring to a legal move in a lawsuit clearly intended merely to harass, delay or embarrass the opposition. frivolous acts can include filing the lawsuit itself, a baseless motion for a legal ruling, an answer of a defendant to a complaint which does not deny, contest, prove or controvert anything, or an appeal which contains not a single arguable basis (by any stretch of the imagination) for the appeal. a frivolous lawsuit, motion or appeal can result in a successful claim by the other party for payment by the frivolous suer of their attorneys’ fees for defending the case. judges are reluctant to find an action frivolous, based on the desire not to discourage people from using the courts to resolve disputes.
