I agree with Mr. Selik and would add that if you are representing yourself in civil court, you are expected to know and adhere to all the rules that apply to us lawyers. It is a violation of the Rules of Professional Conduct for us to use criminal charges to gain leverage in a civil matter. Although you cannot be disciplined or disbarred for violations of the Rules, since you are not a lawyer, you can be pretty sure of pissing off a judge if you blatantly violate them.
