The Stanford Law School Securities Class Action Clearinghouse and Cornerstone Research recently released their analysis of securities class action filings in 2012. They report that 152 new securities class actions were filed last year, a 19 percent decline from the 188 new filings in 2011.
Of particular interest is the observation that only thirteen cases arising from merger and acquisition transactions were filed in federal courts in 2012, as compared to 43 in 2011 and 40 in 2010. “Evidence indicates,” the report states, that merger and acquisition litigation is “now being pursued almost exclusively in state courts after the unusual jump in federal M&A filings in 2010 and 2011.” Though such litigation typically arises under state law, plaintiffs often have the option to frame their claims as violations of the federal securities laws or bring them in federal court by invoking diversity jurisdiction.
