The court found that the applicant had obtained a judgment and taxed costs against the respondents, which remained unsatisfied. Given that execution against government entities is not available through ordinary means, the applicant's only recourse is to seek an order of mandamus. The court applied the test for granting leave in judicial review, determining that the application was neither frivolous nor vexatious and disclosed an arguable case. Consequently, the court exercised its discretion to grant leave to the applicant to commence substantive judicial review proceedings for mandamus.
