Ann Lipton informs us that:
Sean Griffith recently wrote a book chapter explaining how plaintiffs’ merger-related challenges developed over time. Plaintiffs began by seeking disclosure-only settlements, but after Trulia stamped out the practice in Delaware, plaintiffs began bringing claims in federal court challenging corporate proxies under Rule 14a-9. And once they got there, they realized they did not have to limit themselves to merger litigation, and began bringing other kinds of proxy-related claims, and eventually these morphed into individual, rather than class, actions.
Ann goes on to ponder DGCL 220 books and records inspections in the M&A context.
