The tenant of a commercial building in Manhattan violated its lease by acquiring insurance that provided coverage for damage due to many typical acts of terrorists but which expressly carried a binder stating that “terrorism is excluded,” a unanimous Court of Appeals decided June 3.

Also June 3, in separate cases the Court removed an administrative hurdle for a couple who wants to clear their Manhattan apartment building of all rent-stabilized tenants and convert it into a private residence and decided that New York City, not the owners of property adjacent to its sidewalks, is liable for maintaining the sidewalk wells in which trees are embedded.
