[martial arts] deadly sport

[Dangerious P. Cats]

I had this idea of a space setting that is a loose deconstruction/satire of much of your classic space sci fi (primarily Star Trek and series like it). One of the species in setting, a proud warrior race type, will often resort to trial by combat and personal duels to resolve things. The issues for them is that all of their martial arts have become highly ritualised but because they all practice the same art (the society has very strict laws in order to make it a mono-culture) none of them have noticed. Killing the opponent is often the intent in legal disputes so the fighting skills are designed to kill, the issue is just that when put against more practical fighting skills of any other species in the setting, even the same type of skills (striker vs striker, etc) the war arts of the proud warrior race are at a disadvantage because of their ritualisation. I guess the question is how to represent this in the Martial Arts rules?
