The Bill's Policy Memorandum (para 57) argues that:
Making the increased maximum level of fiscal fine of £500 permanently available to prosecutors as a non-court disposal allows prosecutors to continue to deal with less serious offending appropriately, freeing up capacity in the criminal courts system for more serious cases.
In addition, it states that:
the pre-pandemic scale had not been changed since it was introduced in 2008, and its maximum of £300 would now be the equivalent of almost £430 if inflation is taken into account
fiscal fines in excess of the pre-pandemic maximum of £300 made up roughly 2% of those issued between 7 April 2020 and 25 July 2024.
