The survey appears to be the first of its kind. The only previously known survey of WRAs' prosecution record was carried out in 1985 by Imperial College and Loughborough University, and focussed on offences involving hazardous waste (ENDS Report 130, p 7).
NAWRO's survey shows that 49 English WRAs completed 262 successful prosecutions, involving a total of 584 charges, in 1991/2 (see table ).
