Abigroup Contractors Pty Ltd v Algons Engineering Pty Ltd

Abigroup Contractors Pty Ltd (Abigroup) and Algons Engineering Pty Ltd (Algons) were the parties involved in a dispute before the New South Wales Court of Appeal. The core of the disagreement concerned the interpretation and application of a clause within their construction contract, specifically relating to the payment of an amount claimed by Algons.

The central legal issue before the Court of Appeal was whether Abigroup was entitled to set off an amount it claimed against a payment due to Algons under the contract. This involved determining the proper construction of clause 14.1 of the contract, which dealt with Abigroup's right to deduct or set off amounts from payments to Algons. The Court also had to consider the implications of Abigroup's purported exercise of this right.

The Court of Appeal found that Abigroup's purported exercise of its right of set-off under clause 14.1 was invalid. It reasoned that the clause required Abigroup to provide Algons with a notice specifying the amount it intended to set off and the reasons for that deduction. Abigroup had failed to provide such a notice, and therefore, its attempt to set off the amount was ineffective. The Court applied the principle that contractual rights, particularly those involving deductions or set-offs, must be exercised strictly in accordance with their terms.

The Court of Appeal ordered that Abigroup pay Algons the sum of $1,100,000, plus interest, representing the amount that Abigroup had wrongly withheld.
