Mealey's (November 18, 2016, 6:08 PM EST) -- AUSTIN, Texas — A Texas appeals panel on Nov. 16 affirmed summary judgment for a movie theater owner in a premises liability case, saying that a moviegoer who says she slipped on a wet substance and fell in the theater could not identify the substance, prove how long it had been on the floor and show whether the theater owner should have had knowledge of the hazard (Melissa Fontenette-Mitchell v. Cinemark USA Inc., No. 03-16-00201-CV, Texas App., 3rd Dist.; 2016 Tex. App. LEXIS 12255)....
