Very few people write like they talk. For examples, I can’t speak Latin, so I would guess that most judges would rather you not speak Latin.
I like to personalize each party by name. It’s hard to keep straight plaintiff v defendant, or appellant v appellee. I prefer you refer to the parties by their name. Please, please try to avoid using initials (IBM is ok).
A court’s should not decide a case based on feeling or a belief. So, please don’t argue “I feel that the evidence was insufficient”; or “I believe that the trial court erred. . . .” Instead, you should argue “The evidence was insufficient,” or “The trial court erred because . . . .”
