Keydata Corporation v. United States

Keydata (plaintiff) and the United States (defendant), acting for NASA, agreed the government would begin leasing Keydata's computer room on January 1, 1969, with the government paying $39,000 for improvements; Keydata failed to vacate on time, and the government cancelled its lease the next day and withheld the $39,000. Keydata, as the landlord's assignee, sued for the $39,000, arguing the landlord had only promised the right of possession, not actual possession, making the government's cancellation improper.
