Article 44

If the request for enforcement is accepted, the court shall substitute for the sanction involving deprivation of liberty imposed in the requesting State a sanction prescribed by its own law for the same offence. This sanction may, subject to the limitations laid down in paragraph 2, be of a nature or duration other than that imposed in the requesting State. If this latter sanction is less than the minimum which may be pronounced under the law of the requested State, the court shall not be bound by that minimum and shall impose a sanction corresponding to the sanction imposed in the requesting State.

In determining the sanction, the court shall not aggravate the penal situation of the person sentenced as it results from the decision delivered in the requesting State.

Any part of the sanction imposed in the requesting State and any term of provisional custody, served by the person sentenced subsequent to the sentence shall be deducted in full. The same shall apply in respect of any period during which the person sentenced was remanded in custody in the requesting State before being sentenced insofar as the law of that State so requires.

Any Contracting State may, at any time, deposit with the Secretary General of the Council of Europe a declaration which confers on it in pursuance of the present Convention the right to enforce a sanction involving deprivation of liberty of the same nature as that imposed in the requesting State even if the duration of that sanction exceeds the maximum provided for by its national law for a sanction of the same nature. Nevertheless, this rule shall only be applied in cases where the national law of this State allows, in respect of the same offence, for the imposition of a sanction of at least the same duration as that imposed in the requesting State but which is of a more severe nature. The sanction imposed under this paragraph may, if its duration and purpose so require, be enforced in a penal establishment intended for the enforcement of sanctions of another nature.
