"Contrariwise, does total ignorance of his rights inevitably mean that it is impracticable for him to present his complaint in time? In my opinion, no. It would be necessary to pay regard to his circumstances and the course of events. What were his opportunities for finding out that he had rights? Did he take them? If not, why not? Was he misled or deceived? Should there prove to be an acceptable explanation of his continuing ignorance of the existence of his rights, it would not be appropriate to disregard it, relying on the maxim "ignorance of the law is no excuse." The word "practicable" is there to moderate the severity of the maxim and to require an examination of the circumstances of his ignorance. But what if, as here, a complainant knows he has right, but does not know that there is a time limit? Ordinarily, I would not expect him to be able to rely on such ignorance as making it impracticable to present his complaint in time. Unless he can show a specific and acceptable explanation for not acting within four weeks [it is now 3 months] he will be out of court."
