This section applies to section 63D material which—
If the person has previously been convicted of a recordable offence which is not an excluded offence, the material may be retained indefinitely.
In subsection (2), the reference to a recordable offence includes an offence under the law of a country or territory outside England and Wales where the act constituting the offence would constitute a recordable offence if done in England and Wales (whether or not it constituted such an offence when the person was convicted).
In this section "excluded offence" has the meaning given by section 63F(11) (read with section 63F(12)).
