If nobody else is interested, since I somewhat do it already, I can be the "law advisor" for the Tribunal, Charging for advice is a silly notion though, the only way I could see people charging for this being viable is if they were going to be directly responsible for any bad advice they give and/or being able to make bribes to bend the legalities under certain circumstances. Which to my understanding would kind of undermine the whole point of this....
If this is needed? Not really people already are doing this to begin with, if anything it might help direct them to them quicker, but in the end it may lead to more unnecessary buracracy which will just distract people more-so from day to day things (IE - lead to people trying to get more laws, for the grey areas).
Maybe it will be a good thing though to help enforce the illusion of power over people or make others feel more rebellious (at least sooner in a "non-damaging" way)
The aspect of law replacement, is a dangerous notion and will really depend on the people involved--I mean imagine if I was allowed to do that?!
It will be interesting to see what happens with this--but I still think its not really needed, as it is geared towards vets rather than giving newer people roles...
Just my rambling opinion, take as you want...
