The case involves a dispute between Preston Corporation and a printing firm, Edward Leong & ORS, over unpaid printing charges. Preston claimed it withheld $500 that was overcharged and refused to pay extra charges for film positives, disputing the printers' claimed ownership. The printers sued for the unpaid amounts. The key issue was whether quotations from the printers constituted binding offers forming a contract, or were merely invitations to treat. The Federal Court ultimately found the quotations were invitations to treat, so any terms regarding film ownership in them did not form part of the actual contract between the parties. It ruled in favor of Preston Corporation.
