The Storting and the Monarchy are already court systems, even if they haven't been named such, dealing with many important what-ifs, so why not make it the most fair and orderly type of court-system possible?
Just for interest's sake, how many appeals have there actually been?
EDIT: And to add to my first paragraph, everytime a law gets made, that moves the region further into law, and by extension politics, and every time a law is changed or wide-scale reforms are suggested as are already being suggested by just about every campaigner in the current elections, that also changes the landscape of what the region is, even if it is in subtle ways, so trying to maintain a status-quo might go against the very nature of existence, as everything changes, all the time, and will continue to do so. The region already looks very differently from what I would imagine it looked like in the very beginning. So it might even be a pointless and losing battle to fight change.
EDIT 2: If one looks at the world as a sentient species, politics become fairly unavoidable, as demonstrated by even very young children's grasp of the changing nature of the environment around them, and their realisation that they have to adapt with ever more creative means to keep up with nature and not be swept aside by it. I'm sounding a bit too philosophical now, but hopefully my main point of the inevitability of change is coming over well enough.
EDIT 3: Oh, right, I forgot to link my little speech about change with court systems. It was partly in reply to your earlier question on my campaign page about your concerns for having an actual law student here and involved with the law and by extension politics, and partly to try to convey to you that you could give this a trial-run (the court of appeals thing) and see what happens and if it's as broken and inactive as you fear it might be, as a dynamic approach to a new situation. If it doesn't work, it can always be scrapped, and the old laws returned to power. It would consist only out of one person as I'm suggesting it, so if an active player gets chosen, then the inactivity concern gets lessened very much.
