Section 21A(1) of the Prosecution of Offences Act 1985 (c. 23) (“the POA 1985”) requires a court, at the times listed in section 21B of the POA 1985, to order a person convicted of an offence to pay a charge in respect of relevant court costs (the “criminal courts charge”). This duty does not apply in the cases or classes of case prescribed by the Lord Chancellor (section 21A(3)).
