Russell wrote:Normally subjects create new knowledge of their own accord. [...] But Law's are made in Court and by Governments. Seems very different from my lay point of view, or is it?
This exact point was made by your great uncle Bertrand in the chapter on Aristotle's logic in History of Western Philosophy
. The study of law creates no new knowledge since it derives it principles from authoritative texts.
You can state what the law is or, if it is not known in a particular case, speculate what it might be. However, no amount of academic speculation can make law, though it may, as atticus says, be influential. What Professor Newark effectively did was to anticipate a problem and consider it. His reasoning was accepted by the HoL.
