According to the article, this case is important for all companies that conduct internal investigations as the federal appeals court decision effectively preserved attorney-client privilege protections.
  • Fifth Circuit: FCA Not Applicable to Claims That Didn’t Involve Federal Funds, Entity July 8, 2014 — BNA Federal Contracts Report Andy Liu spoke with Bloomberg BNA about the Fifth Circuit’s decision in United States ex rel. Shupe v. Cisco Sys. Inc. According to Liu, “The case serves as a reminder that although the FCA has a broad reach, it is not without limits.” The case found False Claims Act did not apply to allegations that telecommunications firms presented material false claims.
  • High Court Could Rein In Old FCA Claims With KBR Case July 2, 2014 — Law360 Andy Liu talks to Law360 about the False Claims Act case before the Supreme Court of the United States, Kellogg Brown & Root Services Inc. et al. v. U.S. ex rel. Carter, that raises questions about the law’s statute of limitations during periods of war.
  • DOJ Asks Justices To Reject Potential Landmark FCA Case June 3, 2014 — Law360 Andy Liu discussed with Law360 the arguments surrounding the DOJ having recently urged the U.S. Supreme Court not to take up a False Claims Act case that raises questions about the law’s statute of limitations during periods of war.
  • Justices Leave FCA Pleading Dispute To Circuits, For Now March 31, 2014 — Appellate, Corporate, Employment, Government Contracts, Health, and Life Sciences Law360 Andy Liu tells Law360 that because there are so many FCA suits being filed each year, and with whistleblowers bringing so many complaints forward, “it’s likely that many opportunities will arise for a Rule 9(b) clash to finally become ripe.’ There won’t be any shortage of cases in the future,…The Rule 9(b) issue will be raised again.'”
  • DOJ Skittish About Supreme Court Review Of FCA Pleading February 27, 2014 — Government Contracts Law360 Andy Liu talks to Law360 about Rule 9(b) and the misunderstanding about what the Rule means for the government. This article looks at “the open-ended interpretation of how Rule 9(b)’s pleading requirements apply to FCA litigation.” Liu says that the language in the Rule’s brief, “misreads the purpose of Rule 9(b), which is supposed to protect defendants by giving them fair notice of claims against them, safeguard them against spurious accusations and reputational harm, and reduce the possibility of meritless fraud claims that are based on speculation.”

  • 5th Circ. Kickback Ruling Further Squeezes Contractors July 29, 2013 – Law360 Andy Liu explains to Law360 how a recent Fifth Circuit ruling that allows the government to punish companies for Anti-Kickback Act violations may be hard to measure in terms of practicality reach. According to Liu, this is because, “the government already has a more powerful tool to fight most contract fraud in the False Claims Act, which allows for trebled damages.” Liu continues, “It remains to be seen how much of an impact this will have, given that the conduct in Anti Kickback Act cases will often fall under the False Claims Act as well. …They often go hand in hand. If you look at a lot of the kickback cases, especially those that are coming out of the wars in Iraq and Afghanistan, many of those cases are brought under both statutes.”
  • False Claims Act Settlements Often are Business Deals July 22, 2013 — Federal Times Andy Liu provides insight as to why government contractors sometimes have a tough decision on whether to settle a case or go to trial, and why it may have less to do with what side of the law the contractors are on, and more to do with cost-benefit analysis. The attorneys note, “investigative and legal costs alone can reach into the hundreds of thousands of dollars before a case even gets to trial. Plus, contractors can risk debarment or suspension.” Liu explains, “attorneys always insist upon provisions in any settlement deal indicating that the client-contractor denies the allegation that gave rise to the case.”
  • Whistleblowers: Impact of Expanded Whistleblower Protections Unclear as Enforcement Begins July 9, 2013 — BNA Federal Contracts Report The enhanced whistleblower provisions for contractors may prove to be more of a headache than not. This is because the protections will expand the scope or covered actions, whereas “previously, whistleblower protections only applied to employees of prime contractors doing business with the Defense Department and the National Aeronautics and Space Administration,” explains Andy Liu. In addition to setting a three-year statute of limitation to report wrongdoing, the new provisions also expand to cover reports of “abuse of authority,” about which Liu clarifies, “though ‘abuse of authority’ is defined as an arbitrary exercise of authority inconsistent with performance of the contract, the term still creates uncertainty as to what is covered.”
  • FCA Whistleblowers Forced To Go It Alone As DOJ Drags Feet April 12, 2013 — Law360 Andy Liu discusses how there is an increase in the number of whistleblowing from competitors filing whistleblower suits with the DOJ, rather than traditional corporate insiders acting as the whistleblowers.
