Disability discrimination: End user of contract worker's services was "principal"

Where there is an unbroken chain of contracts between an individual and an end user, the end user should be regarded as the "principal" within the meaning of the contract-worker provisions contained in s.12 of the Disability Discrimination Act, the EAT holds in MHC Consulting Services Ltd v Tansell and others [1999] IRLR 677. So a contract worker who was employed by a company ("C") which supplied his services ultimately to an end user ("A") but through another company ("B") under a contract between B and A, could bring discrimination proceedings against A.
