2The repeal by this Act of sections 80 and 81 of the Crime and Disorder Act 1998 does not affect the authority of any guidelines with respect to sentencing which have been included in any judgment of the Court of Appeal given before the commencement of that repeal (“existing guidelines”), but any existing guidelines may be superseded by sentencing guidelines published by the Sentencing Guidelines Council under section 170 of this Act as definitive guidelines.
