The archaic action of reversing a gavel decision; ceremonial reversal of judgment.
Present participle of disgavel. An extremely rare institutional or legal term that would have applied to formal reversal of court decisions.
The fact that this word exists—even though it's virtually never been used—tells us that English speakers in the 1500s-1600s trusted that their verb-formation system (dis- + noun to verb) would always create new words as needed, even without using them much.
