Brexit: Legal Position of Withdrawal Agreement

Debate between Lord Keen of Elie and Lord Howard of Lympne

Monday 3rd December 2018 Lords Chamber

[Lord Keen of Elie]

I thank the noble and learned Lord for his observations. His last comment is not the position under the agreement. It is not for the arbitral tribunal per se to simply impose an alternative agreement to the backstop, so let us clear that out of the way.

Let us look at the terms of the Northern Ireland protocol itself. If the backstop comes in, it will continue until superseded by an alternative agreement that the parties consider renders the existing backstop in the protocol no longer necessary. That is perfectly clear. It does not address the situation in which one or other of the parties simply fails to obtemper their legal obligations under the Northern Ireland protocol, including the obligation to use their best endeavours to arrive at a new arrangement in place of the existing backstop. In that event, the matter will ultimately go to the arbitral tribunal. Pursuant to Article 178, it has certain powers. It can impose financial penalties, just as the EU can impose financial penalties on a member that does not obtemper its obligations under EU law. The arbitral panel will have the power to impose financial obligations on parties who are in breach. If they do not then obtemper their obligations, it has the power to allow for the suspension of an obligation under the terms of the protocol.

These are temporary measures that would be taken to ensure that a party ultimately performs its obligations under the treaty. Failing that, there is the issue of Article 60 of the Vienna convention. However, I do not believe that anyone anticipates that we are going to go down that road. It is very clear that, for political reasons, it would not be in the interests of the EU, any more than those of the United Kingdom, to prolong the backstop in the Northern Ireland protocol any more than is absolutely necessary to maintain the integrity of the Good Friday agreement and the open border on the island of Ireland.

[Lord Howard of Lympne (Con)]

My Lords, the noble Baroness, Lady Chakrabarti, asked my noble friend whether he could identify any precedent for a country handing over such a wide range of vital issues affecting its national interest to a panel of arbitrators. Does he have an answer to that question?

[Lord Keen of Elie]

It is not uncommon for very material issues pertaining to the territorial integrity of a country to be put into the hands of a third party. I cite the recent case of Bolivia and Chile before the International Court of Justice, where judgment was delivered on 1 October this year, with regard to the failure to agree over the issue of access to the Pacific.
