RESTRICTIVE FORCE OF THE AMENDMENT
But the absolute right to a trial of the facts by a jury may not be impaired by any blending with a claim, properly cognizable at law, of a demand for equitable relief in aid of the legal action or during its pendency. Such aid in the federal courts must be sought in separate proceedings.[33] Federal statutes from Revised Statutes (§ 723) through the Judicial Code (§ 267), prohibiting courts of the United States to sustain suits in equity where the remedy is complete at law, serve to guard the right of trial by jury, and should be liberally construed.[34] So also should Equity Rule 30, requiring the answer to a bill in equity to state any counterclaim arising out of the same transaction; such rule was not intended to change the line between law and equity, and must be construed as referring to equitable counterclaims only.[35] Nor may the distinction between law and equity, so far as federal courts are concerned, be obliterated by State legislation.[36] So, where State law, in advance of judgment, treated the whole proceeding upon a simple contract, including determination of validity and of amount due, as an equitable proceeding, it brought the case within the federal equity jurisdiction on removal. Ascertainment of plaintiff's demand being properly by action at law, however, the fact that the equity court had power to summon a jury on occasion did not afford an equivalent of the right of trial by jury secured by the Seventh Amendment.[37] But where State law gives an equitable remedy, such as to quiet title to land, the federal courts will enforce it if it does not obstruct the rights of the parties as to trial by jury.[38] An order of the Court of Claims attempting to reinstate a dismissed case in violation of plaintiff's right to dismiss violates the latter's right to trial by jury and may be corrected by mandamus.[39]
Judge and Jury
LINE DRAWN BY THE COMMON LAW
As was noted above, the primary purpose of the amendment was to preserve the historic line separating the province of the jury from that of the judge, without at the same time preventing procedural improvement which did not transgress this line. Elucidating this formula, the Court has achieved the following results: It is constitutional for a federal judge, in the course of trial, to express his opinion upon the facts, provided all questions of fact are ultimately submitted to the jury;[40] to call the jury's attention to parts of the evidence he deems of special importance,[41] being careful to distinguish between matters of law and matters of opinion in relation thereto;[42] to inform the jury when there is not sufficient evidence to justify a verdict, that such is the case;[43] to direct the jury, after plaintiff's case is all in, to return a verdict for the defendant on the ground of the insufficiency of the evidence;[44] to set aside a verdict which in his opinion is against the law or the evidence, and order a new trial;[45] to refuse defendant a new trial on the condition, accepted by plaintiff, that the latter remit a portion of the damages awarded him;[46] but not, on the other hand, to deny plaintiff a new trial on the converse condition, although defendant accepted it.[47]
In 1913 the Court held, in Slocum v. New York Life Insurance Company,[48] that where upon the evidence a federal trial court, sitting in New York, ought to have directed a verdict for one party but the jury found for the other contrary to the evidence, the amendment rendered it improper for a federal appeals court to order, in accordance with New York practice, the entry of a judgment contrary to the verdict; that the only course open to either court was to order a new trial. While plainly in accordance with the common law as it stood in 1791, the decision was five-to-four and was subjected to a heavy fire of professional criticism urging the convenience of the thing and the theory of the capacity of the common law for growth.[49] It has, moreover, been impaired, if not completely undermined by certain more recent holdings. In the first of these,[50] in which the same Justice spoke for the Court as in the Slocum Case, it was held that a trial court had the right to enter a judgment on the verdict of the jury for the plaintiff after overruling a motion by defendant for dismissal on the ground of insufficient evidence. The Court owned that its ruling was out of line with some of its expressions in the Slocum Case.[51] In the second case[52] the Court sustained a United States district court in Arkansas, in an action between parties of diverse citizenship, in rejecting a motion by defendant for dismissal and peremptorily directing a verdict for the plaintiff. The Supreme Court held that there was ample evidence to support the verdict and that the trial court, in following Arkansas procedure, had acted consistently with the Federal Conformity Act.[53] In the third case,[54] which involved an action against the Government for benefits under a war risk insurance policy which had been allowed to lapse, the trial court directed a verdict for the Government on the ground of the insufficiency of the evidence and was sustained in so doing by both the circuit court of appeals and the Supreme Court. Three Justices, speaking by Justice Black, dissented in an opinion in which it is asserted that "today's decision marks a continuation of the gradual process of judicial erosion which in one-hundred-fifty years has slowly worn away a major portion of the essential guarantee of the Seventh Amendment."[55] That the Court should experience occasional difficulty in harmonizing the idea of preserving the historic common law covering the relations of judge and jury with the notion of a developing common law is not surprising.
WAIVER OF RIGHT OF TRIAL BY JURY
Parties have a right to enter into a stipulation waiving a jury and submitting the case to the court upon an agreed statement of facts, even without any legislative provision for waiver.[56] "* * * Congress has, by statute, provided for the trial of issues of fact in civil cases by the court without the intervention of a jury, only when the parties waive their right to a jury by a stipulation in writing. Revised Statutes sections 648, 649."[57] This statutory provision for a written stipulation, however, does not preclude other kinds of waivers.[58] But every reasonable presumption should be indulged against a waiver.[59] None is to be implied from a request for a directed verdict.[60]
