Commentary on Sections Part 9: Enforcement Chapter 4: Equality of terms Effect
420.A person who wishes to bring a claim for breach of an equality clause or rule or to apply for a declaration about the effect of such a clause or rule must normally do so within six months of the end of the employment contract. In certain circumstances, this section gives a claimant more time to make a claim. This applies where the employer conceals certain information from the claimant or where the claimant has an incapacity (as defined in section 141). Members of the armed forces have an additional three months in which to bring a claim because they must first make a complaint under the service complaint procedures.
