First of all; I fully concur with YMMV, so of course you can give anything as little or great important or even give it an complete makeover.
Secondly - I would never prefer nor condone my saga to become a rampage of Wizard's Wars. I actually even play in Stonehenge and we haven't had a single War yet and I don't know if it will ever happen. And if I ever had players who wanted to play the bully part I think I would seriously had botched my presaga aligning af expectations. Some might enjoy it - In most cases I wouldn't personally. I also only believe the setting is able to ruin a saga if you let it - in other words, that's if the troupe isn't cohesive.
Thus I certainly didn't speak in favor of the right of might in itself - I just argueed the question of the essence of the Code and Hermetic Law, something I found that some of the former posts had lost sight of. This isn't the same as advocating rampant use of Wizard's War but rather to stress that the use of Wizard's War is regulated not by law but by the political realities - being that this alone would make most sane magi think twice before declaring a War. And I do believe that even though weak tribunals might make it easier I would still make rampant War's an improbability. Not because of law but because of realities.
"Endangering the Order" is actually an explicit High Crime which, whether catch-all or not, I don't believe is used this way that often - especially if you look past the obvious kind of endangerment by interfering with mundane affairs. And in the context of excesive use of Wizard's War (the one time it was used in this regard in the TMRE cited as an exeptional case) I find the "we the powerful and many don't approve of you the one"-formulation might more appropriately be rephrases "we who are powerful because we are many don't approve of you because you as the one is far more powerful than we".
The citation of "certain conditions" from the Peripheral Code only relates to the processual conditions mentioned in the same paragraph; namely the process of how to proper declare the War. This is in the Periphal Code seen as the conditions to let you step outside of the boundaries of the Hermetic Oath and actually sanction the killing af another magus. These condition are nowhere, to my knowledge, portrayed as "conditions" of fairness or just cause. One Tribunal actually, on advice from Flambeau himself, acknowledged this and acquitted a magus of "wrongfully", or for inadequate reasons, declaring a Wizard's War. This is the only other Tribunal ruling cited on the matter in HoH:TL's expansive Guernicus chapter on hermetic law. I believe the same goes for the Code's phrase of "justly executed" - that the operational term isn't about the reason but the way you conduct a Wizard's War. The way you declare it, and that collateral damage isn't allowed. Which of course has to be completely by the book as you would otherwise not enjoy the counterparts forfeited immunity from the protection normally granted by the Oath. In other words that you are up for Quaesitorial trial on murder if you do not.
To conclude: I think this issue is important in understanding the legal frame of the Order. As a balancing equilibrum and not as just. But I'll also reiterate that I'm not making a case of gunslinger mayhem. My point is just that the mechanism holding people back from overdoing Wizard's Wars is the caps presented by political realities, community sentiment and the discouragement of more level-headed magi quite possibly returning the favor on the "wanna-be-bullies". I think there's plenty of cause to discourage players from going on a rampage by enforcing that the NPC magi are independent and nuanced individuals that will, whether alone or in unison, react to the players choices and actions and if needed be, whether backed by hermetic law or not, sanction them. Either by political moves or by using their own claim on declaring Wizard's War.
This is my prefered take on the issue - and I do believe this is close to the published line but do correct me if I'm ignorant or pigheaded - this however doesn't change my strong adherence to YMMV and these are my preferences only. Whatever makes you tick makes me glad on your behalf!
