Enough is enough.

Kuja, you seem too passionate about certain combatants to be able to judge them.

There. Well, nothing wrong with being passionate, but if you have trouble staying neutral when looking at battles, it is better for you to not judge.

Edit:

It is a good idea to enforce the time limit...and again, I know absolutely nothing about both characters in this match (Err...not really absolutely nothing...) to participate.
