  • Advising on submissions on behalf of a major international food business to the Independent Reviewer of Advertising Standards Authority successfully seeking to overturn an earlier ASA decision on the basis of public law grounds. This case is one of the only times a BCAP Decision has been reversed in favour of the advertiser.
