PROPRIA PERSONA. In his own person. It is a rule in pleading that pleas to
the jurisdiction of the court must be pleaded in propria persona, because,
if pleaded by attorney, they admit the jurisdiction, as an attorney is an
officer of the court, and he is presumed to plead after having obtained
leave, which admits the jurisdiction. Lawes on Pl. 91.
2. An appearance may be in propria persona, and need not be by attorney.
