Evil Emperor

if you sell someone a bar of lead and tell them it's gold should they not be entitled to their money back whenever they want- you have actually committed the crime of fraud after all. Is false advertising any less repugnant.
Even the Sale of Goods Act limits the possibility of action to 180 days. After that time, if you bought lead thinking it was gold, it's nothing to do with Trading Standards.
The ASA ruling does allow people to challenge RA under 'fit for purpose' in the Sale of Goods Act, because it calls into question whether it is able to do the job it was made for. But only for 180 days after the purchase.
The reality is that RA will handle this in exactly the same way L'Oreal handled the same ASA ruling against the claims made for its Wrinkle De-Crease (with Boswelox). The ads changed microscopically to fit the ASA's demands, the product is still on sale and there was no army of wrinkly women demanding refunds for their expensive and pointless face cream.
