Sept. 28, 2018) (holding insurance policy’s grant of discretionary authority is void under Texas law due to certificate being issued after effective date of regulation, and policy renewing after effective date, and holding Plaintiff was disabled from Any Reasonable Occupation where treating doctors certify she can sit at the occasional level, and insurer’s consultants opine Plaintiff can sit frequently, as weighing all evidence together would make capacity likely at low end of frequent range at best).
