The amendments made to the 1995 Act by section 1 have effect in relation to any person who is detained, or who attends or is arrested, as mentioned in subsection (1) of section 15A of the 1995 Act (as inserted by section 1(4)) where the period of detention, attendance or, as the case may be, arrest starts on or after the day on which this Act comes into force.

The amendments made to the 1995 Act by section 3 have effect in relation to any person who is detained under section 14 of the 1995 Act where the period of detention starts on or after the day on which this Act comes into force.

Subsection (4) applies in relation to any person who is detained under section 14 of the 1995 Act where the period of detention began before this Act comes into force.

Despite sections 1 and 3, sections 14 and 15 of the 1995 Act continue, after this Act comes into force, to have the effect they had immediately before that time.
