They may (extremely rarely, in relation to electrical matters) be 'called upon' to make such decisions, and they therefore occasionally have to try, but the courts themselves (the judges/lawyers/jurors) generally will have absolutely no expertise in the area, and therefore will be totally reliant on others ('experts') to guide them in making their decision.There is only one organisation who can decide if you have the skill, and that is the courts.
