Tyco Australia Pty. Ltd. v. Optus Networks Pty. Ltd. & Ors. [2004] NSWCA 333

Tyco Australia Pty. Ltd. v. Optus Networks Pty. Ltd. & Ors. [2004] NSWCA 333

Optus' damages for equipment were to be reduced not just by the second-hand value of leftover equipment but, for certain items, by their full cost on the basis that Optus would have had to acquire them regardless of Tyco's breach, due to their actual use. Costs spent upgrading Blacktown data centre were held to confer a benefit on Optus (freeing up Rosebery), and thus the full expenditure should be deducted from damages. Business recovery savings were collateral and not to be deducted. The Bullock order was set aside for lack of evidential basis that Tyco induced Optus to pursue NDY. The cross-appeal on interest failed since no error was shown in the selected date for pre-judgment interest.

Legal Issues

  1. 1 ['Whether Optus was entitled to the full cost of replacing/cleaning equipment after the incident or if deductions were required for benefits received (e.g. additional equipment left over, upgraded data center).' 'Whether benefits received by Optus (e.g. freed up data center, cancellation of business recovery contracts) were collateral or had to be deducted from damages.' 'Appropriate quantification and deductions from awarded damages for equipment, upgrade expenditures, and business recovery savings.' 'Appropriate award of interest and whether pre-judgment interest should run from a particular date.' 'Appropriateness of the Bullock order for costs against Tyco (and Leighton) in respect of costs payable to NDY.']

Ratio Decidendi

Optus' damages for equipment were to be reduced not just by the second-hand value of leftover equipment but, for certain items, by their full cost on the basis that Optus would have had to acquire them regardless of Tyco's breach, due to their actual use. Costs spent upgrading Blacktown data centre were held to confer a benefit on Optus (freeing up Rosebery), and thus the full expenditure should be deducted from damages. Business recovery savings were collateral and not to be deducted. The Bullock order was set aside for lack of evidential basis that Tyco induced Optus to pursue NDY. The cross-appeal on interest failed since no error was shown in the selected date for pre-judgment interest.
