56. Without prejudice to the generality of regulation 55, where that regulation effects a transfer of rights and liabilities under a contract of employment—
(a)the contract is to have effect from the incorporation date as if originally made between the employee and the governing body, and
(b)without prejudice to sub-paragraph (a), anything done before that date by or in relation to the temporary governing body in respect of that contract or the employee is to be deemed from that date to have been done by or in relation to the governing body,
but no right of the employee to terminate his contract of employment if a substantial change is made to his detriment in his working conditions arises by reason only of the change of employer effected by that regulation.
