In the case of Curtice Brothers Co. v. Catts  48 Vt. 116 (Vt. 1874), Curtice Bros. was a canning plant that contracted to buy tomatoes from the farmer Catts.  Catts reneged on the deal.  In this case, the Court found that specific performance was warranted, and ordered Catts' tomatoes to be seized.  In this case, the Court felt that it was not a matter of whether Curtis was forced to pay a higher price for tomatoes from another farmer, but whether Curtice could obtain tomatoes at all.  If not, they would have to shut down the canning plant.  Curtice's contract to buy all of Catts' tomatoes, is an example of a output contract.
