When confronted with someone asserting this, it can be tempting to demand they cite specific articles in WTO Agreements, but most people aren't equipped to have that discussion...
The EU have put Brexit Preparatory notices highlighting day 1 changes which experts have flagged as hugely disruptive to UK-EU trade.
Trucks not being able to cross borders disruptive.
1. The EU doesn't realize this.
2. The EU realizes this and doesn't care.
Let's consider each.
Seems unlikely.
The @EU_Commission has had the lead on negotiating at the WTO, and fighting disputes on behalf of EU Member States for decades.
They know the WTO and have great lawyers.
In that case, it's fair to ask what you think the WTO will do about it. What are the UK's options?
Well, it can raise a complaint in the relevant Committee and/or it can file a dispute.
Also, the sheer scale of planned disruption means you're talking about hundreds of individual complaints.
But let's assume for the sake of argument the EU loses (they won't) and they're ruled in breach...
The WTO can't force them to change their rules. If the EU doesn't comply, the ONLY thing the WTO Panel can do is allow the UK to levy proportional retaliatory tariffs.
Whatever your position on Brexit, complacency and relying solely on the WTO Rules in the event of a no-deal is folly.
