BRUSSELS, (Reuters) – The European Commission opened two new proceedings against Britain Wednesday following London’s publication of plans to repeal some post-Brexit trade rules for Northern Ireland. It also resumed a challenge that it had previously paused.

Even though fines could be imposed by European Court of Justice in the proceedings, they are likely to take more than one year.

For the 27-member European Union members, the Commission oversees relations to Britain. The Commission stated it wanted to continue talks with Britain, in order to address problems related to shipping British products into Northern Ireland.

British Province is part of the EU single marketplace for goods. This means that imports from other parts of the United Kingdom will be subject to customs declarations, and may sometimes need inspections upon arrival. This arrangement was made to prevent the reintroduction of border controls between Northern Ireland (EU member Ireland) that were removed after 1998’s Good Friday ceasefire.

A EU official claimed that “The British government” had announced again its intent to breach international law. “We do not believe that it requires a lawyer or a court to understand that unilaterally changing an accord is illegal.”
