41. Where a sentence to be enforced in the State is in respect of fewer offences than that for which it was imposed in an issuing state—

(a) by virtue of the partial recognition and enforcement of the sentence, or

(b) by virtue of the adaptation of the sentence by an order under section 40(3) or (5),

the partial recognition and enforcement or adaptation, as the case may be, shall not be deemed to constitute an aggravation of the nature or duration of the sentence.
