An application under Part 5.4 or 5.4A must not be dismissed merely because of one or more of the following:
(a) in any case--a defect or irregularity in connection with the application;
(b) in the case of an application for a company to be wound up in insolvency--a defect in a statutory demand;
unless the Court is satisfied that substantial injustice has been caused that cannot otherwise be remedied (for example, by an adjournment or an order for costs).
