Wal-Mart Stores, Inc. v. AIG Life Insurance Co. (Del. Ch. Dec. 12, 2006), read opinion here.
In this Chancery Court case, the “clean-up doctrine” of equity court jurisdiction was discussed. The court exercised its discretion to retain jurisdiction based on its familiarity with the long history of this case and despite only one remaining claim being common law fraud and not equitable fraud. Footnotes 1 through 3 include the citations to prior court opinions over the long history of this case from both the Chancery Court and the Delaware Supreme Court. Thus, the motion to transfer to the Superior Court was denied.
