In the dispute over Brexit rules for the British province of Northern Ireland, the EU is taking action against London.
This was the Commission's reaction on Wednesday to a law presented at the beginning of the week with which the British government could undermine a joint agreement - the so-called Northern Ireland Protocol.
The government of Prime Minister Boris Johnson wants to force Brussels to reopen the agreement that was only agreed in 2019.
The EU Commission strictly rules this out – and defends itself with three legal procedures: two of these infringement procedures are being initiated and another is being resumed.
They could end up with a case in the European Court of Justice and a fine for London.
Despite repeated requests, the British government has failed to implement the protocol, the EU Commission said.
"This is a clear violation of international law." That is unacceptable, said EU Commissioner Maros Sefcovic, who is responsible for the negotiations between London and Brussels.
Border could exacerbate conflict again
Post-Brexit disputes erupted over how and where goods coming into Northern Ireland from the UK should be inspected.
Both sides want to avoid a border on the island of Ireland amid fears it could result in violence and reignite the Northern Ireland conflict.
The Northern Ireland Protocol is part of the 2019 Brexit deal.
It stipulates that the province, which is part of the United Kingdom, will continue to follow the rules of the EU internal market and the European Customs Union.
This is intended to prevent product controls for the EU member Republic of Ireland in order to prevent the conflict between opponents and supporters of a unification of the two parts of Ireland flaring up again.
But now an intra-British goods border has been created.
