DSB won a motion for summary judgment on behalf of a school district on Long Island in an action commenced by a student who fell down stairs in a school and suffered a concussion and brain bleed requiring surgery. The Court determined that the student’s injuries were not caused by a lack of supervision. The Court further ruled that plaintiffs’ other claims could not be interposed to avoid summary judgment inasmuch as they were not included in the Notice of Claim served on the School District.
