Tokyo Network Computing Pty Ltd v Tanaka

Tokyo Network Computing Pty Ltd (the employer) appealed a decision of the District Court of New South Wales concerning a dispute with its former employee, Mr Tanaka. The central issue revolved around the employer's unilateral reduction of Mr Tanaka's salary during the currency of his employment contract, which Mr Tanaka alleged constituted a fundamental breach of his contract, entitling him to resign and claim damages for wrongful dismissal.

The Court of Appeal was required to determine whether the employer's action in reducing Mr Tanaka's salary amounted to a repudiation of the employment contract. Specifically, the court had to consider whether such a reduction, without the employee's consent, was so significant as to deprive the employee of substantially the whole of the benefit which it was intended he should obtain from the contract, thereby justifying his termination of the contract.

The court affirmed the established legal principle that a unilateral and substantial reduction in an employee's salary by an employer constitutes a fundamental breach of the employment contract, amounting to a repudiation. This principle is rooted in the concept that the agreed salary is a core element of the employment bargain, and its significant alteration without consent fundamentally alters the employer's obligations. By reducing Mr Tanaka's salary without his agreement, the employer evinced an intention no longer to be bound by the essential terms of the contract, thereby giving Mr Tanaka the right to treat the contract as at an end.

The appeal was dismissed, and the employer was ordered to pay Mr Tanaka's costs.
