Many books and movies involve tales of scary creatures who return, ranging from Grendel’s family in the ancient epic of Beowulf to “Where’s My Mummy?”, an underappreciated part of the Scooby Doo multiverse. The topic of briefing waiver returns in the majority opinion ifrom Herczeg v. City of Dallas, which found waiver in a sovereign-immunity case because the opening brief did not address untimeliness or exhaustion of remedies. It distinguished St. John Missionary Baptist v. Flakes, 595 S.W.3d 211 (Tex. 2020), as involving “two grounds [that] were not actually independent but were inextricably intertwined,” while here, “untimeliness and failure to exhaust administrative remedies are independent of the City’s other grounds, which focused on the merits of Herczeg’s claims.” A dissent questioned whether the older authority cited by the majority continued to be viable after Flakes. Justice Garcia wrote for the majority, joined by Justice Smith; Justice Schenck dissented. No. 05-19-01023-CV (March 29, 2021) (mem. op.).
