Commentary on Sections Part 10 – Criminal Justice Chapter 3 – Detention under a Public Protection Order Without Restrictions Section 189 - Effect of custodial sentence
This section applies where a person who is liable to be detained under a public protection order without restrictions is detained in custody in pursuance of any sentence or order passed or made by a court in the UK. This includes an order committing or remanding the person in custody.
If such a person is detained in custody for a period of more than 6 months, or successive periods of time which exceed 6 months in total, then this section provides that at the end of 6 months beginning with the date of the person’s detention in custody he or she ceases to be liable to be detained under the public protection order.
If the person is detained in custody for a period of time not exceeding 6 months, or a period of time not exceeding 6 months in total, and has not ceased to be liable to be detained under the public protection order, then section 244 of the Act applies as if, on the day of discharge from custody, the person had absented him or herself without permission from the establishment he or she is liable to be detained under the public protection order.
