What is Open A Judgement?

Legal Definition
To lift or relax the bar of finality and conclusiveness which it imposes so as to permit a re-examination of the merits of the action in which it was rendered. This is done at the instance of a party showing good cause why the execution of the judgment would be inequitable. It so far annuls the judgment as to prevent its enforcement until the final determination upon it, but does not in the mean time release its lien upon real estate. See Insurance Co. v. Beale, 110 Pa. 32l, 1 Atl. 926. -
