(2) An application for leave under this rule must be supported by an affidavit stating any facts or matters relating to the desirability of the court assuming jurisdiction under this rule, including the place or country in which the person to be served is or possibly may be found, and whether the case is a proper one for the court's jurisdiction.
(3) A sealed copy of every order made under this rule must be served with the document to which it relates.
(4) The court may grant an application for leave if the claimant establishes that —
(a) the claimant has a good cause of action;

(c) the court is the appropriate forum for the trial.
(5) Where the court makes an order under this rule it must also specify the date by which the defendant is required to acknowledge service and defend the claim.
