[Note. The Criminal Procedure and Investigations Act 1996 came into force on 1^st April, 1997. It does not apply where the investigation began before that date. With effect from 4^th April, 2005, the Criminal Justice Act 2003 made changes to the 1996 Act that do not apply to investigations begun earlier. In some circumstances, the prosecutor may be required to disclose material to which the 1996 Act does not apply: see sections 1 and 21.

Part I of the 1996 Act contains sections 1 to 21A. Part II, which contains sections 22 to 27, requires an investigator to record information relevant to an investigation that is obtained during its course. See also the Criminal Procedure and Investigations Act 1996 (Code of Practice) Order 2015 issued under sections 23 to 25 of the 1996 Act.]
