MEMORANDUM *

Appellants, a number of trucking companies, appeal the district court’s order granting judgment on the pleadings. Included in their appeal is a challenge to the district court’s denial of plaintiffs’ motion to remand the case to state court on the ground that the federal court lacked jurisdiction. This court has jurisdiction pursuant to 28 U.S.C. § 1291. We review a district court’s denial of a motion to remand de novo. We reverse and remand with instructions.

As the parties point out, this circuit has not addressed the issue of “fraudulent” or “egregious” joinder of plaintiffs for the purpose of defeating diversity jurisdiction in the federal courts. Other courts have held that plaintiffs may be fraudulently joined if “there is no possibility that [plaintiff] would be able to establish a cause of action against defendants] in state court.”1 The Eleventh Circuit has recognized the additional theory of egregious misjoinder, where the claims of non-diverse plaintiffs have no real connection or nexus to the claims of the diverse plaintiffs.2 For purposes of discussion we will assume, without deciding, that this circuit would accept the doctrines of fraudulent and egregious joinder as applied to plaintiffs.

The trucking companies’ complaint in this case lacked complete diversity because one of the plaintiff trucking companies was a citizen of the same state as one of the defendant engine manufacturers. The manufacturers tried to remove the case to federal court by claiming that the court should ignore the citizenship of the non-diverse trucking company because the company was fraudulently joined. The burden is on the manufacturers, as the parties asserting federal jurisdiction, to establish the fraudulent nature of the joinder of the non-diverse plaintiff, Rehable Carriers Inc. (RCI).3 Because the manufacturers did not meet their burden, we reverse.

We cannot say, on this record, that there is no possibility that RCI could state a claim in California state court. The complaint alleged that RCI purchased the diesel engines that are the subject of this suit. Defendants introduced nothing to refute that claim or to establish that RCI had no connection to California. The fact that plaintiff trucking companies have not provided evidence of any connection between RCI and the State of California is not enough to prove that none exists— defendants bear the burden of proving fraudulent joinder. Given California’s liberal rules on amendment of pleadings, it is very possible that the state court would *730have granted plaintiffs leave to amend their complaint, allowing them to address the deficiencies the defendant manufacturers assert.4 Accordingly, the district court erred by denying plaintiffs’ motion to remand because defendants failed to meet their burden of proving fraudulent joinder.

The engine manufacturers also asserted egregious misjoinder as a basis for finding federal diversity jurisdiction. However, the joinder of RCI was not so improper as to be considered egregious, thereby justifying ignoring RCI’s presence in the case.5 The claims of all plaintiffs, including RCI, involved the purchase of allegedly faulty diesel engines from one of the defendant manufacturers. Therefore, there seems to be some connection or nexus between the claims of the non-diverse plaintiff and the claims of the diverse plaintiffs.

Especially considering that 28 U.S.C. § 1441 is “strictly construed against removal,” 6 the state court, not the federal court, should decide whether there is a sufficient nexus between RCI and California to support a state court claim. Defendants failed to meet their burden of proving fraudulent or egregious misjoinder before the district court and that court erred by denying plaintiffs’ motion for remand. The district court lacked jurisdiction to hear this case because there was no federal question involved nor complete diversity. Therefore, we remand to the district court with instructions for it to remand the case to the state court.

REVERSED and REMANDED with instructions to remand the case to state court.
