And since when did a piece of paper cover you from negligence...???graham said:If you have the piece of paper you can potentially demonstrate that you weren't negligent. If you haven't then, well how can you prove you did anything?
Wafting a piece of paper infront of a judge to say you are a 'competent leader' won't make fk all difference... If you are qualified or not and you get people trapped/injured/etc underground you are the same, you are liable for their safety....
