No appeal from orders passed ex-parte or by default. Re hearing on proof of good cause for non-appearance

No appeal shall lie from an order passed under Section 54 ex-parte or by default; but in all such cases, if the party against whom judgment has been given appears either in person or by agent (if a plaintiff, within 30 days from the date of such order, and if a defendant within 30 days, after such order has been communicated to him, or after any process for enforcing the judgment has been executed or at any earlier period), and shows good cause for his non-appearance and satisfies the officer making the order that there has been a failure of justice, such officer may, upon such terms as to costs or otherwise as he thinks proper, revive the case and alter or rescind the order according to the merits of the case: Provided that no order shall be reversed or altered without previously summoning the party in whose favour judgment has been given to appear and be heard in support of it.
