The bill was passed three years ago! The descriptions of the law and exemptions are clear – over three years now to decide what to do with an item.
The failure is the antiques trade and has always been. The failure to show any proper proof of age and failure to, in many cases, recognise ivory, as many descriptions are still ‘bone or ivory’ or possibly ivory.
So please stop moaning, the situation could have been prevented by the antiques trade recognising the issue over ivory many years ago but they chose to ignore it.
