In Commerzbank AG v Keen [2007] IRLR 132 CA the Court of Appeal held that an employer did not act in breach of the implied terms of a contract of employment in awarding to a highly paid employee lower bonuses than those recommended by his manager. Further, the terms of employment contracts are not covered by the provisions of the Unfair Contract Terms Act 1977.
In Hoyland v Asda Stores Ltd [2006] All ER (D) 133 CS, the Court of Session holds that despite being described as "discretionary" a bonus scheme was "regulated" by the employee's contract of employment and therefore fell outside the scope of the Sex Discrimination Act 1975.
In Farrell Matthews & Weir v Hansen, the EAT holds that a non-contractual bonus that had been declared constituted wages under s.27(3) of the Employment Rights Act 1996. The employer's failure to pay it therefore amounted to an unlawful deduction from wages.
In Coutts & Co plc v Cure; Royal Bank of Scotland v Fraser, the EAT holds that, in a case where an employer refused to pay a non-contractual bonus to all non-permanent employees, including some fixed-term workers, the tribunal did not err in law by holding that the reason for the less favourable treatment was on the ground of the employees' status as fixed-term workers.
