THE LANDLORD DID NOT OWE A DUTY TO A TENANT TO PREVENT AN ASSAULT BY ANOTHER TENANT; THE LANDLORD’S DUTY IS NOT TRIGGERED UNLESS THE LANDLORD HAS THE AUTHORITY, ABILITY AND OPPORTUNITY TO CONTROL THE ACTIONS OF A TENANT-ASSAILANT; THE ABILITY TO EVICT DOES NOT CONSTITUTE THE REQUISITE AUTHORITY (FIRST DEPT).

The First Department, reversing Supreme Court, determined the landlord did not have a duty to prevent one tenant from attacking another:

… [The landlord] demonstrated prima facie that they were not liable for the third-party defendant’s alleged assault on plaintiff. A landlord has no duty to prevent one tenant from attacking another tenant unless it has the authority, ability, and opportunity to control the actions of the assailant …  Here, defendants had no authority or opportunity to remove Vasquez from the premises prior to the assault. Defendants’ employee testified that defendants were unaware of prior complaints of [the tenant] engaging in violence, and plaintiff acknowledged that before the attack she never complained about [the tenant] being violent. Moreover, the assault upon the plaintiff was not reasonably foreseeable … .

Plaintiff failed to raise an issue of fact in opposition. Defendants’ ability to evict [the tenant] did not constitute the requisite authority, ability, and opportunity to control him … . Plaintiff failed to identify any prior complaints about [the tenant] being violent or making explicit threats of violence. Plaintiff’s generalized complaints about unsupervised children on the complex and about other children engaging in bullying were not sufficient to put defendants on notice that [the tenant] might be violent … . Rodriguez v Madison Sec.
