The High Court struck out proceedings brought by the plaintiff seeking to set aside a final possession order previously made over mortgaged property. The plaintiff had already appealed the original order through the Circuit Court and High Court, with his final attempt to seek leave to appeal to the Supreme Court refused. In this fresh lawsuit, the plaintiff attempted to raise new claims and revisit arguments on the validity of the mortgage, the loan assignments, and alleged misconduct by the lending institutions, arguing for a full plenary hearing rather than a summary process. The High Court held that the case was an abuse of process, as it amounted to an impermissible collateral attack on a matter already conclusively determined, reiterating that parties cannot relitigate issues or raise new grounds that should have been brought earlier. Consequently, the plaintiff’s action was dismissed in its entirety as bound to fail.
