Question: What Hermetic legal recourse exists, if any, for a magus in the following situation?
Due to antagonistic Tribunal relations present in the Saga, Loch Leglean Tribunal decides to retaliate against the Stonehenge Tribunal by bringing up charges during a Loch Leglean Tribunal meeting against certain magi living in Stonehenge. The activities carried out by the Stonehenge magi took place in Loch Leglean, but are considered legal by the magi in question. Loch Leglean is using this as an excuse to punish these magi.
Loch Leglan holds trial whether or not the magi in question appear to defend themselves and declares them guilty. They issue a heavy punitive fine, loss of familiar, and loss of apprentice as the case may be. The magi from Stonehenge Tribunal contest the validity of the charges and the verdict from Loch Leglean. Grand Tribunal is 27 years away, and while appealing it then is always an option, that's too long to wait for a response.
Plot Twist: Due to historical reasons, the Stonehenge Tribunal is a year later. After a year of politicking, the magi in question put forth to vote: an order by the Stonehenge Tribunal for the affected magi to ignore the Loch Leglean verdicts and to neither pay the fine nor surrender their apprentices or familiars.
In short: Other than paying the penalty and using the time to appeal the case to Grand Tribunal, is there any legal recourse - short of Wizard's War - against this verdict from Loch Leglean? Ignoring it will simply be used as an excuse to Wizard's March the magi. What arguments are there about the validity of the Stonehenge Tribunal's order of having its magi simply ignore the verdicts of another Tribunal?
I'm curious to hear the thoughts of other SGs about legal arguments (for and against) in a backdrop where a cold war is heating up to a potential second Schism War, this time led by two Tribunals instead of Houses.
