Security for costs is designed to ensure that a defendant to an action or a respondent to an application does not have to incur the expense of a fulsome defence without the possibility of recovering a portion of her costs against the plaintiff/applicant.
Judges cannot reconsider their decision – once an order is issued, the judge’s job (and jurisdiction to hear further arguments) is done. In very limited cases, a party may ask the court to reconsider after the decision is released but before a formal order is taken out. However, the test to meet is high.
