If you mean the Totally Wicked case, then they lost it. TPD was enacted as a Statutory Instrument into UK law last May, and nothing really can be done about it until at least 2 years after we do the Article 50 business, when we start looking at all the EU laws that we have to amend/do away with under UK law.
Under TPD the max size bottle of nic containing liquid is 10ml (zero nic not affected) and the highest nic content is 20mg/ml, after November it will be illegal for any retailer/supplier in the EU/UK to import or make any nic juice in bottles larger than 10ml (although existing stock can still be sold to public/retailers until May after which that will also be illegal)
Whether we as users will still be able to import larger bottles from say the USA, I presume that will be up to the individual companies (rules in USA) therefore probably NOT.
