When there are multiple defendants in a case, if even just one is a citizen of the state where the lawsuit was filed, a plaintiff can successfully object to removal if the only basis for federal jurisdiction is based on diversity of citizenship. The reason for the rule is that diversity jurisdiction was created by the Founding Fathers of the United States in the Constitution to shield defendants from possible discrimination in a foreign forum (i.e., a state not their home state). When an in-state defendant is being sued in a state court, it is expected that he will not be subject to unfair prejudice. With the exception of class actions under CAFA, every defendant must agree to remove; otherwise, the plaintiff or non-removing defendants can request remand for failure to satisfy the "rule of unanimity".
