In The News
Mr. O'Brien, was featured in a January 15, 2008 Compliance Week article, "Lawsuit Spotlights GC's Risk of Personal Liability," for his comments on the 2006 lawsuit filed by the Department of Justice and the U.S. attorney for the Southern District of Florida against Christi Sulzbach, the former general counsel for Tenet Healthcare. The lawsuit alleges that Tenet's General Counsel knowingly submitted false statements confirming that Tenet was in compliance with federal health care laws. Accoring to O’Brien, "the message to come out of this case is that the government will scrutinize any certification, whether pursuant to a [corporate integrity agreement] or a regulatory obligation, and if it comes to conclude that the certification was problematic, it will take action."
