Where a pastoral scheme is made in pursuance of proposals formulated by a joint pastoral committee appointed under section 13—
(a)the scheme may provide for altering the boundaries between any of the dioceses represented by the joint pastoral committee, and for transferring any benefices, parishes or extra-parochial places affected by the alteration from one diocese to another, but not so as to create or dissolve any diocese;
(b)the scheme may also provide, as respects such areas of the said dioceses affected directly or indirectly by the alteration of boundaries as the scheme may specify, for any of the matters for which a pastoral scheme may provide with respect to an area in one diocese, subject to such modifications as may be necessary or expedient by reason of the application of the scheme to more than one diocese;
Provided that the powers conferred by this section shall be subject to any limitation imposed by instrument sealed by the bishops of the dioceses concerned under section 13, in force at the time when the scheme is made by the Commissioners.
