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 (Sec. 723) through
the Judicial Code (Sec. 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 jur
