What is the test for an intervener to intervene in a personal injury case?

The test for leave to intervene was recently set out in Abbot v. Canada, [2003] 3 F.C. 482 as follows: 1. The applicant for intervention must have an interest in the outcome; 2. The rights of the applicant will be seriously affected by the outcome of the litigation; and 3. The applicant, as Intervener, will bring a different perspective to the proceedings.
