In Griffiths and another v Salisbury District Council [2004] All ER (D) 104 (Feb) CA, the Court of Appeal held that the Implementation Agreement reached as part of the establishment of the new national agreement setting up the National Joint Council for Local Government Services formed part of the contracts of employment of the council's employees. The results of a regrading exercise that was carried out in accordance with the provisions of the Implementation Agreement were therefore incorporated into the employees' contracts of employment as legally binding terms.
