In Unison v Somerset County Council and others EAT/0043/09, the EAT held that the employees "affected by" a TUPE transfer for the purposes of consultation with employee representatives were those who would or might be transferred, those whose job is jeopardised by the proposed transfer, and those with internal job applications pending. The definition did not extend to those who might in the future apply for a vacancy in the part of the undertaking transferred.
In Royal Mail Group Ltd v Communication Workers Union [2009] EWCA Civ 1045 CA, the Court of Appeal held that an employer must inform representatives of employees who may be affected by a TUPE transfer of its considered and genuine view as to the legal implications of the proposed transfer. However, reg.13(2)(b) of the TUPE Regulations 2006 does not impose strict liability on the employer as to the accuracy of that information. Therefore the employer will not be in breach if the information that it gives reflects a genuine but mistaken belief as to the legal implications.
