In Multnomah County’s lawsuit against fossil fuel companies, the federal district court for the District of Oregon adopted a magistrate judge’s findings and recommendations and granted the County’s motion to remand the lawsuit to state court. The findings and recommendations rejected the companies’ arguments based on federal question jurisdiction and on diversity jurisdiction. The district court was not persuaded that the magistrate judge applied an erroneous standard to the analysis of the companies’ argument that the County fraudulently joined the only non-diverse defendant. In addition, the court found that the complaint sufficiently alleged facts to state causes of action against the non-diverse defendant, even in the absence of an alleged misrepresentation by that defendant. The district court also was not persuaded that the magistrate improperly disregarded a declaration establishing that the non-resident defendant was not involved in the alleged misrepresentations.
