Saving provision and transitional defence
12. In any proceedings for an offence of contravening regulation 10(3), (4), (6) or (7), or regulation 11(1) or (3) it is a defence to prove that—
(a)the act constituting the offence was committed in relation to a material or article made with regenerated cellulose film which was manufactured in, or imported into, the European Union before 29 January 2006; and
(b)the act constituting the offence would not have constituted an offence under the Materials and Articles in Contact with Food Regulations 1987(1) as they stood immediately before the coming into force of the Materials and Articles in Contact with Food (Wales) Regulations 2005(2).
S.I. 2005/1647 (W. 128). Those Regulations were subsequently amended by S.I. 2005/3254 (W. 247) and S.I. 2006/2982 (W. 273), but neither of those instruments made amendments that are relevant to this provision.
