Lucas Drilling Pty Limited v Armour Energy Limited

Lucas Drilling Pty Limited, the appellant, appealed against a decision of the primary judge which involved the construction of a contract between the appellant and Armour Energy Limited, the respondent. The appellant had been granted an interlocutory injunction to restrain the respondent from calling on a bank guarantee which the appellant had procured in favour of the respondent. The appellant argued that the primary judge had erred in exercising the discretion to grant interlocutory relief, and that the primary judge's discretion miscarried. The dispute centred on the proper construction of a contractual clause concerning the performance bond. The appellant contended that, due to its accrued rights, it was not obliged to return the performance bond, even after termination of the contract by the respondent. The respondent argued that the appellant had no accrued rights and was obliged to return the performance bond.

The court examined whether the primary judge's discretion in granting interlocutory relief was correctly exercised and if the primary judge's interpretation of the contract was sound. The court found that the primary judge's interpretation of the contract was incorrect and that the appellant was not obliged to return the performance bond due to its accrued rights. The court also found that the primary judge had exercised his discretion to grant interlocutory relief correctly, but that the relief granted was not appropriate given the court's interpretation of the contract. The court found that the primary judge's discretion had miscarried in this respect.

The appeal was allowed, and the orders made on 7 September 2012 were set aside. The moneys paid into court by the respondent pursuant to the orders of 7 September 2012 in substitution of the Performance Bond were to be paid to the appellant together with any accretions thereon. The respondent was to pay the appellant's standard costs of and incidental to the appeal and the application at first instance.
