Mark Flynn sued his landlord, and the building's managing agent, after he was attacked by his ex-girlfriend's companion. (Flynn claimed that security personnel had negligently allowed the perpetrators to enter the building unannounced.)
After the New York County Supreme Court denied a dismissal request, the owner appealed.
Since Flynn's injuries weren't foreseeable, and no "reasonable" security measures would have prevented what occurred, the Appellate Division, First Department, thought the case should end.
Apparently, the ex-girlfriend was a regular visitor to the building, and there had been no indication that she should be denied entry or that "any foul play was in the offing."
Drats!
