In September 2021, Macy's accused the billboard's owner Kaufman Realty of negotiating to lease the space to an online retailer before Macy's most recent lease expired that August. Macy's claimed that the lessee was almost certainly Amazon and filed for an injunction preventing Kaufman from leasing the space to a competitor. Macy's claimed that a 1963 agreement prohibited such a lease "forever" and that an Amazon billboard would be highly visible during the Macy's Thanksgiving Day Parade.
So was the injunction successful?
You nerd-snipped me into digging through court records.
The case was 655669/2021 in the New York County Supreme Court (the Supreme Court is the name for the first-tier courts in NY state).
Docket: https://iapps.courts.state.ny.us/nyscef/DocumentList?docketI...
The parties were in settlement talks and postponed the hearing on an injunction and then settled and dismissed.
Thanks, it's a bit frustrating when a piece of old news is reported without a followup. Happens all the time, and due to news agencies not bothering to report the not-so-interesting stuff, it's often difficult to find out what happened after.
