No but see if i keep the right details about the room in my minds eye, and point my magic hammer at my enemy, and chant the laws just right, they have to do it. Or you shoot a fireball.

Thats why you keep your focus the fringe on the flag; that keeps you firmly in earth magic; if you get distracted and think about the benches while chanting the law youre gonna do either fire or wood magic, and you do not want to accidentally summon a tree in a court room. Especially not if youre citing a powerful law when you do.
