On April 17, 2013, Select Medical Corporation (Select Medical) filed suit in federal district court seeking to enjoin Delaware from enforcing an unclaimed property assessment issued for years that had been resolved already through the state’s voluntary disclosure program. In 2006, Select Medical entered into Delaware’s voluntary disclosure program for the years 1997-2001. As part of the process, the company escheated approximately $17,000 to Delaware and paid approximately $300,000 in unclaimed property to states other than Delaware. On the same day that Delaware cashed the company’s escheatment check, it notified the company that it was being placed under audit. Using a third-party auditor, Delaware demanded payment of $297,436 for the period 1997-2001 based on an estimate that looked at the amount of property owed to other states for the period 2002-2008. Unable to resolve the matter with the state, Select Medical filed a lawsuit, alleging that Delaware exceeded its authority under state law by estimating an unclaimed property liability through extrapolation of amounts paid to other states for a different period, even though actual records were available from which any liability could be determined and the owners of any unclaimed property could be identified. Select Medical also alleged a variety of federal common law and constitutional violations. (Select Medical Corp. v. Del. Sec’y of Finance, Del. Dir. Of Rev., & Del.
