Quanta Software International Pty Ltd v Quanta Systems Ltd [2004] FCA 1182

The applicant’s letter of 1 December 1994 operated as a representation to the respondent that the Licence had been terminated pursuant to the Deed of Settlement. The respondent, acting reasonably, adopted this assumption and, to its detriment, ceased to enforce rights or seek payments under the Licence and proceeded with development and marketing of the software. The applicant is estopped from now asserting that the Licence remains in force. Thus, the applicant’s claim must be dismissed.
