Tenant sued landlord for negligence after he slipped and fell on the building staircase. Landlord asked the court to dismiss the case without a trial, claiming that it wasn’t responsible for tenant’s injuries. The court ruled for landlord in part, and both sides appealed. The appeals court also ruled for landlord only in part. Landlord didn’t have constructive notice of any wet condition on the staircase. The building’s porter stated that he had inspected the stairs 15 minutes before tenant fell and didn’t observe any wet condition.
