Notes:
SCS commenced collecting fiscal fines in all courts from December 2007. Figures for 2007-08 are therefore not directly comparable with other years
Figures for JP court fines are not directly comparable between years prior to 2010-11 due to the progressive nature of court unification.
The total fines income remitted to HMT includes all sheriff court fines income and the non-retainable element of the JP court fines income
- the JP court element (statutory) is not separately identifiable.
Total remitted to HMT includes fines, confiscations and forfeitures.
There was a significant single confiscation of £17 million in 2010-11.
