I was kicked out from the MD programme at Université de Sherbrooke due to a procedural failure. The school covered it up, I was devastated.
Six years later after filing the equivalent of a FOIA I realized something didn’t add up. I filed for judicial review, it was denied on prescription grounds (delay) so the court had no need to examine the case on its merits. I appealed, the judgment held.
So yeah, delay/prescription is a real and super serious thing, especially in administrative law. Very strict.
