Non-production of logged DEEC Book: covered period corrected to 31.3.2002 under Policy Circular, clarifying Public Notice scope. Correction to a previous policy circular: the date listed under 'Cases covered under Public Notice No.5 dated 6.4.1999' is amended to the intended terminal date, thereby clarifying the coverage period for cases concerning non-production of the logged DEEC Book and aligning the Public Notice's temporal scope.
