Rule: Courts are under an obligation to inform the parties where an appeal lies. A lower court judge pronounced a judgment after hearing lengthy arguments from plaintiff's and defendant's advocates. He did not inform the parties about the period of limitation for filing an appeal under latest amendment. The plaintiff failed to appeal on time and requested the higher court for condonation of delay on the ground that the lower court judge failed to fulfil his obligation as he was not informed about the appeal. Will the higher court consider this ground as sufficient cause for condonation of delay?
