 These provisions covered both "Cartledge"-like situations and cases where the injured party, while aware of his injuries, does not connect them to the true cause until more than three years after the injuries were sustained.The act had a limited retrospective effect - it covered injuries that had happened before the Act came into force if an action had not been brought.If a judgment had already been made in a case, the Act could not apply to it, meaning the Act actually had no effect on the "Cartledge" case itself.
