Hertz removed the action to federal court, then was subsequently dismissed from the case. The remaining parties \u2014 plaintiffs and Hambardzumyan \u2014 were all California residents. Plaintiffs moved to remand for lack of complete diversity. Hambardzumyan, the only remaining defendant, did not oppose.<\/p>\n<h2>The Court&rsquo;s Holding<\/h2>\n<p>Magistrate Judge Stephanie S. Christensen granted the motion to remand. The court explained that diversity is determined from the face of the complaint (Gould v. Mutual Life Ins. Co. of N.Y.; In re Digimarc Corp. Derivative Litig.), and the complaint clearly alleged that plaintiffs and Hambardzumyan are California residents. With Hertz dismissed and no longer a party \u2014 and Hambardzumyan&rsquo;s opposition constructively withdrawn by his nonparticipation \u2014 the burden to establish removal jurisdiction could not be met. Without complete diversity, the court lacked subject matter jurisdiction.<\/p>\n<h2>Key Takeaways<\/h2>\n<ul>\n<li>When a removing defendant is dismissed from the case, the diversity analysis defaults back to the parties remaining; if complete diversity is lacking, remand is required.<\/li>\n<li>The party who removed bears the burden of establishing federal jurisdiction even after their dismissal \u2014 and that burden cannot be met if the remaining parties are non-diverse.<\/li>\n<li>An unopposed motion to remand will be granted where the face of the complaint shows lack of complete diversity.<\/li>\n<li>Remand under 28 U.S.C. \u00a7 1447(c) is required &ldquo;at any time before final judgment&rdquo; if the court determines it lacks subject-matter jurisdiction.<\/li>\n<\/ul>\n<h2>Why It Matters<\/h2>\n<p>This is a clean illustration of how the dismissal of one diverse defendant can defeat federal jurisdiction in a multi-defendant removed case. Practitioners should remember that diversity is monitored throughout the case; the dismissal of the diverse party that removed the case can require remand to state court.<\/p>\n<p><a href=\"recap\/gov.uscourts.cacd.982202\/gov.uscourts.cacd.982202.23.0.pdf\">Read the full opinion (PDF)<\/a> &middot; <a href=\"https:\/\/www.courtlistener.com\/opinion\/10789934\/suren-grigorian-et-al-v-armen-hambardzumyan-et-al\/\">Court docket<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Magistrate Judge Stephanie S.
