22.—Recognition or enforcement of an order (other than a provisional order) for recovery of maintenance made by a court in a jurisdiction other than the State may not be refused—

(a) by reason only of the fact that the court which made the order had power to vary or revoke it, or

(b) on the ground that, under the rules of private international law of the State, the court concerned had not jurisdiction by reason of the fact that the respondent was not resident or present in that jurisdiction at the date of the commencement of the relevant proceedings, provided that at that date the claimant was resident there.
