Article 10 Continued enforcement

In the case of continued enforcement, the administering State shall be bound by the legal nature and duration of the sentence as determined by the sentencing State.

If, however, this sentence is by its nature or duration incompatible with the law of the administering State, or its law so requires, that State may, by a court or administrative order, adapt the sanction to the punishment or measure prescribed by its own law for a similar offence. As to its nature, the punishment or measure shall, as far as possible, correspond with that imposed by the sentence to be enforced. It shall not aggravate, by its nature or duration, the sanction imposed in the sentencing State, nor exceed the maximum prescribed by the law of the administering State.
