Litigation partners David Rein and Matthew Schwartz and litigation associate Brian Gottlieb have authored an article for Practical Law in which they offer guidance on defending parallel actions asserting claims under the federal securities laws in state and federal court. The authors discuss how the U.S. Supreme Court’s ruling in Cyan. v Beaver County Employees Retirement Fund has changed the landscape for securities litigation, and offers insights on handling lawsuits alleging overlapping federal securities law claims in both state and federal court. The authors also suggest measures companies may take to mitigate the risks of parallel securities litigation.
