I don't know if you can see the text in this screen shot, but underneath the first line (which displays the main objective of the battle), the law is displayed. In this particular battle, actions by Nu Mou are forbidden. Nu Mou are a race in the game. During my current play through, my black mage is a Nu Mou. I was particularly frustrated by this law set as I would have benefitted by my Nu Mou's magic abilities. Being discouraged from using a specific race might be a form of racism in games if the same race were always discouraged, but FFT A-2 generally mixes things up. Sometimes Moogles are forbidden.
While this time I waged war on the beasts of the land without my Nu Mou companion, it doesn't mean I can't ignore the judges laws next time around. I don't think I'm anywhere near the end of A-2, but in FF Tactics Advance, the conclusion of the storyline revealed that the laws were corrupt in some way (at least that's how I remember it). Will A-2 end the same way?
