Hmmm, as much as I thought Petro won, I don't think overturning the fight is the answer. If they don't like the clinch rule, then change it for next time. What is with this 'overturning the results' deal?? There have been plenty of top fighters in the sport who don't whine and get decisions overturned because they should not have been on the losing end. Pretty much every top fighter. Heck, I thought Petro should have clearly lost to Buakaw, and then he showed a bit of unsportsmanlike conduct after the fight was declared a draw. He got the benefit of the doubt. Not to mention other fights Buakaw clearly didn't get the benefit of the doubt both in K1 and otherwise.... But no decisions were overturned....the rules kept changing...etc. I'm wondering if the other Thai fighters in the competition support this.
If it wasn't outright highway robbery, you chalk it up to experience and keep at it until you get the clear win next time, instead of making another fighter have to suffer worse for something obviously not his fault.
If the refs or judges were at fault, do something about that then. Why penalize innocent fighters?
