As of today it became a criminal offence if you fail to confirm your name, date of birth and nationality without reasonable excuse if required to do so.
Confirmation of Nationality – Section 162 of the Policing and Crime Act 2017 came into force today, inserting section 86A into the Courts Act 2003. Subsections (1) and (2) of section 86A provide:
“(1) A person who is a defendant in proceedings in a criminal court must provide his or her name, date of birth and nationality if required to do so at any stage of proceedings by the court.
(2) Criminal Procedure Rules must specify the stages of proceedings at which requirements are to be imposed by virtue of subsection (1) (and may specify other stages of proceedings when such requirements may be imposed).”
