No everything will be fine if everything ends happily. Which in aviation is about 99.99% of the time. It is the 0.01% time when you may end up in court.
In this example say the person died on board and it was deemed by the coroner that if they had flown at max speed and no delay the person's life could have been saved. That is when they will start going through things with a fine tooth comb and asking why wasn't procedure followed which could possibly lead to lawsuits.
For those who are arguing for a laissez-faire approach to following rules are you seriously telling me that if by your actions or lack thereof a lawyer isn't going to be putting you on the stand and asking if you are familiar with the company's manuals and if you are why you didn't follow what is written even though there is a copy on your flight deck?
Now my point is that if you did as per the procedures you can then point the finger at the writers of the manual or whatever. If however you did your own thing you are basically on your own. You will have to be explaining why you did what you did and what tested methodology you used to come up with that decision. Can be done but it will interesting to say the least.
For those talking about a Nuremburg defense not being applicable after a read of wikipedia it would seem that it would be after a particular ruling in the USA.
