A scheme under section 1 of this Act which makes provision with respect to the pensions, allowances or gratuities which are to be, or may be, paid to or in respect of a person to whom that section applies and who is incapacitated or dies as a result of an injury sustained, or disease contracted, in circumstances prescribed by the scheme may make the like provision in relation to any other person, being a person who is employed in a civil capacity for the purposes of Her Majesty’s Government in the United Kingdom, whether temporarily or permanently and whether for reward or not, or is a person holding office in that Government and who is incapacitated or dies as a result of an injury or disease so sustained or contracted.

No scheme under the said section 1 shall make any provision which would have the effect of reducing the amount of any pension, allowance or gratuity, in so far as that amount is directly or indirectly referable to rights which have accrued (whether by virtue of service rendered, contributions paid or any other thing done) before the coming into operation of the scheme, unless the persons consulted in accordance with section 1(3) of this Act have agreed to the inclusion of that provision.

Where an order has been made under section 1(7) of this Act, any scheme under that section may provide for the payment to the Minister out of the fund specified in the order of benefits or other sums paid by him in accordance with the scheme to or in respect of persons to whom that section applies by virtue of the order, together with any administrative expenses incurred in connection with the payment of those sums, and for the payment into that fund of contributions paid in accordance with the scheme by or in respect of those persons and of any transfer values received in respect of them.

Any scheme under the said section 1 may provide for the determination by the Minister of questions arising under the scheme and may provide that the decision of the Minister on any such question shall be final.

Where under any such scheme any question falls to be determined by the Minister, then, at any time before the question is determined, the Minister may (and if so directed by any of the Courts hereinafter mentioned shall) state in the form of a special case for determination by the High Court, the Court of Session or the Court of Appeal in Northern Ireland any question of law arising out of the question which falls to be determined by him.

Where such a case is stated for determination by the High Court, an appeal to the Court of Appeal from the determination by the High Court shall lie only with the leave of the High Court or of the Court of Appeal; and where such a case is stated for determination by the Court of Session then, subject to any rules of court, the Minister shall be entitled to appear and be heard when the case is being considered by that Court.

Any scheme under the said section 1 may amend or revoke any previous scheme made thereunder.

Different schemes may be made under the said section 1 in relation to different classes of persons to whom that section applies, and in this section “the principal civil service pension scheme” means the principal scheme so made relating to persons serving in employment in the home civil service or the diplomatic service.

Before a scheme made under the said section 1, being the principal civil service pension scheme or a scheme amending or revoking that scheme, comes into operation the Minister shall lay a copy of the scheme before Parliament.

Notwithstanding any repeal made by this Act, the existing civil service superannuation provisions, that is to say, the enactments and instruments listed in Schedule 2 to this Act, shall, with the necessary adaptations and modifications, have effect as from the commencement of this Act as if they constituted a scheme made under the said section 1 in relation to the persons to whom that section applies, being the principal civil service pension scheme, and coming into operation on the said commencement and may be revoked or amended accordingly.
