Commercial Litigation, Corporate Defense, and Investigations

Pro Bono and Public Interest Litigation 

In addition to her commercial litigation, Lauren has diverse pro bono and public interest practices. Currently, Lauren is litigating a First Amendment case involving the removal and restriction in multiple Florida school districts of “And Tango Makes Three,” a widely lauded children’s book that conveys that same-sex relationships and families with same-sex parents exist; that they can be happy, healthy, and loving; and that same-sex parents can adopt and raise healthy children. She also represented a clean energy nonprofit organization in a precedent-setting case before the Utah Public Service Commission to demonstrate the costs and benefits of solar energy as well as public servants in a class action suit against student loan servicer Navient, alleging that the company prevented them from accessing their federal public service loan forgiveness. Lauren has authored two amicus briefs, a Ninth Circuit brief advocating for economically sound applications of antitrust law to complex facts in the healthcare industry, and another asking the U.S. Supreme Court to review a Texas state court death sentence on behalf of several organizations that advocate for victims of family violence.

Representative Matters

  • American Federation of Teachers union: Represented members in a settlement of a nationwide class action lawsuit with Navient, one of the nation’s largest student loan servicers, challenging Navient’s practices with respect to advising federal student loan borrowers on Public Service Loan Forgiveness (PSLF). The team secured a novel class settlement under which Navient agreed, among other things, to enhance its practices for public service workers (teachers, nurses, Legal Aid workers, firemen and policemen, for example) and, in addition, to contribute millions to a nonprofit organization that provides education and student loan counseling to public service workers. Selendy Gay successfully secured a unanimous affirmance of the approval on appeal in front of the U.S. Court of Appeals for the Second Circuit.
  • Fairfield Sentry Limited (in liquidation) et al.: Represented foreign representatives of funds in Chapter 15 proceedings in Bankruptcy Court seeking to recover approximately $6 billion in redemption payments from hundreds of entities arising out of the Madoff scheme.
  • A major academic institution: Conducted an internal investigation of an apparent hate crime on a university campus and analyzed the school’s overall security systems and safety compliance policies to recommend changes to those systems and protocols. 
  • Vote Solar: Represented a clean energy nonprofit organization, in a precedent-setting case against Rocky Mountain Power (RMP) before the Utah Public Service Commission (PSC) to demonstrate the costs and benefits of solar energy in the state’s net metering program. RMP, Utah’s electricity utility, conducted a study of how customers with rooftop solar panels impact the grid and the utilities overall demand for power. In partnership with Vote Solar, Selendy Gay prepared our own rigorously developed proposal to be evaluated in parallel with RMP’s. The PSC, which traditionally sides with RMP, found in our favor that many of the values of customer generated solar do exist and included them in their export rate, including avoided generation capacity costs and avoided distribution capacity costs.
  • McKinsey & Co.: Represented McKinsey in a bench trial in bankruptcy court in Houston, Texas, in which Jay Alix, through Mar-Bow Value Partners, objected to the debtors’ application to retain McKinsey on the basis that McKinsey’s Bankruptcy Rule 2014 disclosures were noncompliant, and that McKinsey was not disinterested. The case, In re Westmoreland Coal Co., Inc., was dismissed after 8 days of trial testimony after McKinsey reached a comprehensive settlement regarding future bankruptcy disclosures with the U.S. Trustee.
  • Organizations that advocate for victims of family violence: Filed an amicus brief asking the U.S. Supreme Court to review a Texas state court death sentence, arguing that the Texas court’s ruling conflicts with Supreme Court precedent and ignores well-established developmental psychology. The brief was filed on behalf of the National Family Violence Law Center, the California Protective Parents Association, and the Domestic Violence Legal Empowerment & Appeals Project.
  • Healthcare Economics Scholars: Drafted Ninth Circuit amicus brief on behalf of 13 economics scholars advocating for economically sound applications of antitrust law to complex facts in the healthcare industry.
  • A high-net-worth client: Represented client in a matrimonial action involving cutting edge legal issues regarding contractual interpretation of and statutory application to the client’s prenuptial agreement, spendthrift trusts, income, cash flow, and “lifestyle” analyses for purpose of alimony.
