In Ariana M v. Humana Health Plan of Texas, Inc., 2018 WL 1096980 (5th Cir. March 1, 2018), a divided Fifth Circuit issued an en banc ruling that fiinally overturned Pierre v. Conn. Gen. Life Ins. Co., 932 F.2d 1552 (5th Cir. 1991) and concurred with every other Circuit that Firestone Tire & Rubber Co. v. Bruch, 489 U.S. 101 (1989) applies the default de novo standard of judicial review to both legal and factual determinations, thus paving the way for the Texas ban on discretionary clauses (TEX. INS. CODE § 1701.062(a), along with similar bans by 25 other states - Nat'l Ass'n of Ins. Comm'rs, Prohibition on the Use of Discretionary Clauses Model Act ST-42-3-6 (2014), http://www.naic.org/store/free/MDL-42.pdf.) to trigger de novo review of benefit denials of health and disability benefit claims.
