Plaintiff slipped in a puddle of urine in the staircase of her building owned by the New York City Housing Authority. The plaintiff had affidavits from several nonparty witnesses who alleged that urine puddles in the staircase were a recurring problem. However, the plaintiff failed to disclose the names of those witnesses. As such, the court granted the Housing Authorities’ motion for summary judgment, finding that the plaintiff failed to show that the building owner had actual or constructive notice of the gross and hazardous condition.
