In Patel v Oldham Metropolitan Borough Council, the EAT held that a teacher who had suffered from two related medical conditions that had each lasted less than 12 months, but which, when taken together, had lasted more than 12 months, was protected by the DDA. The length of consecutive impairments could be aggregated for the purpose of determining the duration of an impairment. This principle will only apply when the two conditions are related, which is a question of fact. This case has potentially wide implications, enabling claimants to aggregate periods of separate but related impairments of less than 12 months each, and we will keep you informed of any appeal.
