Equal pay: Job evaluation scheme did not have retrospective effect

In 1) Bainbridge & Ors 2) Redcar & Cleveland Borough Council v 1) Redcar & Cleveland Borough Council 2) Williams EAT/0424/06 & EAT/0031/07 the Employment Appeal Tribunal held that successful equal pay claims confer the right to up to six years' back pay prior to the institution of proceedings. However, where an equal pay claim is based on a job evaluation scheme, equal pay may be awarded only from the date on which the scheme was completed.
