In Paterson v Commissioner of Police of the Metropolis [2007] IRLR 763, the EAT held that a policeman who suffered from dyslexia, which disadvantaged him when undergoing assessment for promotion, had an impairment that had a substantial and long-term adverse effect on his ability to carry out normal day-to-day activities. The dyslexia therefore amounted to a disability within the meaning of the Disability Discrimination Act 1995.
