Regulation 21 Superannuation contributions
A person entitled to retirement compensation under regulation 18 or 19 shall pay an amount equal to any sum which was paid to him by way of return of superannuation contributions (including any interest) after ceasing to be employed—
if the provisions of his last relevant pension scheme enable him to be credited with benefits attributable to that sum, to the fund authority, and
in any other case, to the compensating authority.
If the person does not pay as specified in paragraph (1), his retirement compensation shall be reduced by an annual amount the capital value of which is equal to the amount of the said superannuation contributions.
For the purposes of this regulation the expression “superannuation contributions” shall include payments made by the person in respect of added years, any additional contributory payments made by him and any other payments made by him for the purpose of increasing the benefits to which he would have become entitled under his last relevant pension scheme.
Any sums paid to a compensating authority under this regulation in respect of returned contributions shall be applied for the payment of compensation which the authority is liable to pay under this Part of these regulations.
