In Austrian, Lance & Stewart v. Hastings Props., 87 Misc. 2d 25, [Sup.Ct.N.Y.Co.1976], the plaintiff, a professional corporation of attorneys, moved for summary judgment upon a promissory note. Defendant objected to plaintiff appearing pro se, but the court permitted plaintiff to represent itself. (See, Austrian, 87 Misc. 2d at 26.) The court noted that 'the reason corporations are required to act through attorneys is that a corporation is a hydra-headed entity and its shareholders are insulated from personal responsibility. There must therefore be a designated spokesman accountable to the court. This reasoning does not apply in the case of a professional corporation where personal liability attaches and each member (in this case a law firm) is qualified to appear before the court and argue its case.' (Supra, at 26.)
