Don’t fall into the trap of restating the other side’s argument as a prelude to attacking that argument. A true advocate never dedicates a sentence to explaining the opponents’ position.
For example, if the issue is whether your client has defrauded customers, don’t dedicate a sentence to the other side’s argument that “Courts will pierce the corporate veil where the corporation has defrauded its customers.” Instead, restate the argument from your client’s angle: “The courts will not allow a pierce where a corporation is adequately capitalized unless there are clear markers of fraud.” Or work opposing authority into an “although” clause to avoid dedicating a whole sentence to discussing that authority. For example, say “Although courts have pierced the veil where corporations have defrauded their customers, our clients never acted fraudulently.”
Make your opponents do their own work. Don’t do it for them.
