parties stemmed from the distinction which was required to be drawn between “necessary” and “indispensable” parties. This distinction is set forth in the hoary case of Shields v. Barrow, 17 How. 130, 139, 58 U.S. 130, 139, 15 L.Ed. 158 (1854):
The court here points out three classes of parties to a bill of equity. They are: 1. Formal parties. 2. Persons having an interest in the controversy, and who ought to be made parties, in order that the court may act on that rule which requires it to decide on, and finally determine the entire controversy, and do complete justice, by adjusting all the rights involved in it. These persons are commonly termed necessary parties; but if their interests are separable from those of the parties before the court, so that the court can proceed to a decree, and do complete and final justice, without affecting other persons not before the court, the latter are not indispensable parties. 3. Persons who not only have an interest in the controversy but an interest of such a nature that a final decree cannot be made without either affecting that interest, or leaving the controversy in such a condition that its final termination may be wholly inconsistent with equity and good conscience. (Footnote omitted).
The Shields v. Barrow formula was a concerted attempt to formalize the join-der doctrines which had arisen in the courts, of equity. Up until the eighteenth century equity required joinder of all interested parties, but recognizing that practical difficulties and obstacles often made this impossible, relaxed its standard of complete adjudication of a controversy when faced with compelling equity.2 As noted by Professors Kaplan and Hazard, supra n. 2, equity’s attitude changed during the 1700’s when the concept of “complete adjudication” gained the upper hand. On the other side of the aisle, the common law had developed joinder criteria which paralleled the parties substantive rights and obligations. The essence of the common law joinder doctrine was that joint rights or obligations demanded joint adjudication.3 The common law’s approach, to say the least, lacked the flexibility of the earlier equity practice.
The rise of the concept of the “complete decree” encroached upon the flexible and rather pragmatic approach to joinder problems which the earlier equity practice had enjoyed and fostered. It was this encroachment which Professor Hazard believes gave rise to the “indispensable” party concept4 which was formalized in this country in Shields v. Barrow, supra.
In its most favorable light Shields v. Barrow states the proposition that
“if a court can proceed to a meaningful decree without affecting the interest of the absent person, that absent person is at most a necessary party; if the circumstances are such that the court cannot so proceed, then the absent one is an indispensable party.”
Reed, supra n. 1 at 343. While this formulation, as an abstract proposition, is consistent with the present Rule 19, any flexibility or pragmatism envisioned by the Supreme Court in Shields was soon eliminated by courts which latched upon such unguarded words as “separable” and “ without' affecting that interest ” in an attempt to devise a mechanical test to apply to joinder

In his article Professor Hazard has done an excellent job of documenting the rise of the indispensability doctrine and its application under equity, common law and the predecessor of the present Rule 19.
