delivered the opinion of the Court.
This is a suit in equity, brought in the District Court for Western Missouri by respondent, a New Jersey fire insurance company, against petitioners, citizens of Missouri, to cancel two insurance policies. One, for $3,000, was issued to petitioners, who are husband and wife, to insure them against loss by fire of a building which they held as tenants by the entirety. The other, for $1,500, was issued to the husband to insure his personal property located in the building. On motion to dismiss the bill of complaint for want of equity and want of jurisdiction the district court dismissed the suit on the ground that the amount in controversy did not exceed $3,000. Its decree was reversed by the Court of Appeals for the Eighth Circuit, 75 F. (2d) 808. This Court granted certiorari to settle an important question of federal law affecting the jurisdiction of federal courts.
The bill of complaint alleges that the petitioners procured the two policies from respondent by representing *67 that they would not effect insurance on the property in excess of a stated amount; that thereafter they did effect insurance with respondent and other companies in excess of that amount, and in excess of the value of the insured property, and then caused the property to be destroyed by fire, all in execution of a conspiracy between them. ’ It avers that petitioners have filed proofs of loss with respondent, and that they threaten to and are about to begin suits at law against respondent to recover the full amounts of its policies.
As the two policies are separate contracts, with different beneficiaries, insuring different properties, it is conceded that no suit at law could be maintained upon them in the federal courts since neither exceeds $3,000, the amount requisite for the jurisdiction of the federal courts, and the two independent causes of action upon them could not be joined in a-single suit at law. The Court of Appeals held that the jurisdictional requirement was satisfied by the expedient of seeking cancellation of the two policies in a single suit in equity, wherein their amounts might be united. It recognized that jurisdiction cannot ordinarily be conferred on a federal court by joining in a single suit separate causes of action in none of which is the amount involved more than $3,000 although their aggregate exceeds that sum.

v.
Northeastern R. Co.,
We address ourselves only to the question whether the equitable relief is warranted, leaving aside doubts whether the present case, by the allegation that the insurance was effected and the loss caused pursuant to a conspiracy, is brought within the peculiar doctrine of Woodmen of the World v. O’Neill, supra, where the conspiracy was to abuse the processes of the courts by the prosecution of groundless suits.
1. This Court has recently pointed out that equity will not compel the cancellation and surrender of an insurance policy procured by fraud where the loss has occurred and a suit at law to recover the amount of the loss is pending or threatened.

2. Section 24 of the Judicial Code, 28 U. S. C. § 41, restricts the jurisdiction of the district courts whether at law or in equity to controversies in which the amount involved exceeds $3,000. Section 267 of the Judicial Code, 28 U. S. C. § 384, forbids the maintenance of suits in equity in the courts of the United States “ in any case where a plain, adequate and complete remedy may be had at law.” It is true, as this Court has often pointed out, that the inadequacy prerequisite to relief in a federal court of equity is measured by the character of remedy afforded in federal rather than in state courts of law.

v.
Rutherford County,
3. As the nature of the relief sought, cancellation of the insurance policies, and the inability of - the federal courts to hear the suits at law for want of the jurisdictional amount, do not warrant equitable relief, it is evident that the remedy which respondent seeks depends on the slender thread of its right to ask the federal court of equity to save it the possible inconvenience of trying two law suits instead of one. Avoidance of the burden of numerous suits at law between the same or different parties, where the issues are substantially the same, is a recognized ground for equitable relief in the federal courts. See
Ogden City
v.
Armstrong,
“ In any case where the facts bring it within the possible jurisdiction of the court, . . . the decision must depend largely upon the question of the reasonable con *71 venience of the remedy, its effectiveness and the inadequacy of the remedy at law. . . . Each case, if not brought directly within the principle of some preceding case, must, as we think, be decided upon its own merits and upon a survey of the real and substantial convenience of .all parties, the adequacy of the legal remedy, the situations of the different parties, the points to be contested and the result which would follow if jurisdiction should be assumed or denied; . . . The single fact that a multiplicity of suits may be prevented by this assumption of jurisdiction is not in all cases enough to sustain it. It might be that the exercise of equitable jurisdiction on this ground, while preventing a formal multiplicity of suits, would nevertheless be attended with more ,and deeper inconvenience to the defendants than would be compensated for by the convenience of a single plaintiff, and where the case is not covered by any controlling precedent the inconvenience might constitute good ground for denying jurisdiction.”
Lord Hardwick, in laying down the principles which should guide the award of a bill of peace, the progenitor of the modem bill to- avoid multiplicity of suits, thought that there was no occasion for the relief where the asserted right could be established by “ one or two actions at law.”

v.
Herbert,
2 Atk. 483. While it need not be said that under no circumstances could the maintenance of two suits with common issues be so burdensome or inconvenient as to justify equitable relief, see
McHenry
v.
Hazard,
The bare fact that a plaintiff is threatened with two suits on the same document and having common issues has been held not to be enough to call for their trial in a single suit in equity.
Druon
v.
Sullivan,
The grounds for relief to a single plaintiff which will deprive two or more defendants of their right to a jury trial must be real and substantial and its necessity must affirmatively appear. See

v.
Boise City,
Finally it is to be noted that this tenuous ground for the exercise of equity powers is put forward as the sole medium by which suits may be withdrawn from the jurisdiction of the state courts which could not have been removed to or otherwise brought into the federal courts. While the consequences of the court’s grant of equitable relief cannot affect its power, they nevertheless have an important bearing on the exercise of the judicial discretion which must guide a court of equity in determining whether it should grant or withhold a remedy which it is within its power to give. Its discretion may properly be influenced by considerations of the public interests involved. See
United States ex rel. Greathouse
v.
Dern,
*74 We think the threatened injury to respondent is of too slight moment to justify a federal court of equity, in the exercise of its discretion, in according a remedy which would entail denial of a jury trial to the petitioners and withdraw from the jurisdiction of the state courts suits which could not otherwise be brought into the federal courts.
Reversed.
