A legal practitioner who has participated in the affairs at issue in litigation at a level that goes beyond providing legal advice cannot properly appear as counsel for a party in those proceedings. Where a legal practitioner has aligned himself so closely with a client's case that he displays an interest going beyond that of a legal practitioner, or has performed acts materially related to the dispute before the court, he should only be permitted to appear as an agent rather than as legal practitioner. Additionally, affidavits should be sworn before a commissioner of oaths who is independent of the office in which they are drawn, and affidavits sworn before an attorney or partner of an attorney acting for the deponent are objectionable and should not be admitted.
