The present participle of disaffirm; the ongoing action of reversing or denying the validity of something.
From disaffirm + -ing (gerund/present participle suffix). Used in legal writing to describe actions currently in progress.
Using 'disaffirming' in legal documents creates a formal, active sense—'the court is disaffirming the lower court's ruling' sounds more authoritative than 'the court will reverse' because the gerund form emphasizes the action itself.
