Mr. Sheanin served as co-lead counsel in In re Wells Fargo Collateral Protection Insurance Litigation (C.D. Cal.), a class action on behalf of more than 2 million automobile loan borrowers on whose accounts Wells Fargo and National General Insurance Corporation force-placed automobile insurance regardless of whether they maintained sufficient independent insurance.  Plaintiffs alleged that Wells Fargo billed borrowers for charges that they did not actually owe, and often did not detect, with lasting damage to their finances and creditworthiness. Mr. Sheanin was responsible for litigation, discovery, and settlement strategy.  Defendants settled for more than $432 million.

In In re Lithium Ion Batteries Antitrust Litigation (N.D.

In In re Credit Default Swaps Antitrust Litigation (S.D.N.Y.), Mr. Sheanin represented the Los Angeles County Employee Retirement Association in a class action on behalf of all purchasers and sellers of credit default swaps (CDS), alleging that thirteen of the world’s largest banks conspired to restrain the efficient trading of CDS, thereby inflating trading costs.  Mr. Sheanin was involved in all aspects of litigation, discovery, and expert analysis. The case settled for $1.86 billion, one of the largest antitrust settlements in history. (Prior to joining Robins Kaplan LLP)

Mr. Sheanin represented direct purchaser plaintiffs in In re TFT-LCD (Flat Panel) Antitrust Litigation (N.D.
