From various quarters, whispers or even open calls are growing for an extension to the UK’s Article 50 period which finishes, unless extended, on 29th March 2019. Most of those talking about an Article 50 extension seem to assume that the UK only has to ask for such an extension, and it will be granted unto us. However, the European Union is not the beneficent Lord mentioned in the gospel according to St Matthew Chapter 7, Verse 7 (the Sermon on the Mount), and confidence that the EU will just grant any extension that the UK asks of them is likely to prove very misplaced. The so-called “Cooper-Boles amendment”, which was defeated in the House of Commons on 29th January by 321 to 298 votes, seems to be based on such an assumption. This sought to pave the way for a Bill which would impose a legal duty on the Prime Minister to “seek an extension of the period of two years specified in Article 50(3) of the Treaty on European Union to a period ending on 31 December 2019”, or to such other date as the House of Commons might decide on a future motion. The legalities of an Article 50 extension But let us look at the legalities both of how an Article 50 extension can be granted, and the legal effects of such an extension. It is important to understand both in order to assess the likely reaction of the European Union and its Member States to an Article 50 extension request from the UK. The governing provision is the closing words of Article 50(3) of the Treaty on European Union: “3. The Treaties shall cease to apply to the State in question from the date of entry into force of the withdrawal agreement or, failing that, two years after the notification referred to in paragraph 2 [i.e. 29 March 2019], unless the European Council, in agreement with the Member State concerned, unanimously decides to extend this period.” The effect of an extension, if granted, is to postpone the UK’s date of exit from the European Union, so that the whole panoply of rights and obligations of EU membership would continue to apply to the UK as a Member State during the extended period. So the UK’s obligation to pay into the EU budget would automatically be extended. But most importantly in view of its political repercussions, both the right of the UK to be represented by MEPs in the European Parliament and its obligation to choose them by direct elections would continue to apply to the UK. On the face of it, this means that if an extension takes us past May, the UK must then hold a fresh round of European Parliament elections. There is a little bit of wriggle room, in that if the extension period terminates before the new European Parliament assembles on 2nd July 2019, such elections could be avoided as pointless. But if the extension is beyond that date, it is very difficult so see how the elections could be avoided. That would mean that Nigel Farage would be re-elected to the European Parliament, probably in present circumstances as part of an increased phalanx of members of his new Brexit Party. And the EU’s internal legal advice is apparently that once elected, the UK MEPs would be entitled to remain members of the European Parliament for the rest of their five-year terms, regardless of when the UK leaves the EU. This would completely up-end the political agreements which have been reached for the sharing out of the seats which (it had been assumed) would be vacated by the UK in the European Parliament. This is a huge spanner in the works for any Article 50 extension longer than three months. No doubt the ‘creative law-bending’ departments of the EU would be hard at work to think of ways round this problem, but at the moment it looks like a formidable difficulty. But another problem arises if an extension is for three months or less – say to 29th June. It is not possible to treat such an extension as a “more of the same” extended negotiating period. This is because the current European Parliament term will end on 18th April 2019 prior to the European Parliament elections. Article 50(2) requires that the European Parliament must consent to any Withdrawal Agreement before the EU can conclude it. So, at most, an extension to the Article 50 period which stops short of 2nd July would allow merely an extra three weeks for an agreement to be finalised and concluded. As to how an Article 50 extension is granted, it should be noted that this requires the unanimous consent of each EU27 Member State within the European Council. This is actually a more stringent rule than for an Article 50 agreement to be concluded, which can be done by Qualified Majority Vote (QMV). The effect of this requirement is to place enormous power in the hands of each individual Member State which may have demands it wants to make. If the UK comes crawling along, begging for an Article 50 extension, what better time to dig in and extract some useful concessions? What terms will be imposed on an Article 50 extension? Let us then turn to the question of whether, and on what terms, an Article 50 extension might be agreed if the UK asks for it. As is evident from Article 50(3) quoted above, such an extension is not simply a matter of choice for the UK, but requires the unanimous consent of all EU27 Member States. First, the EU collectively is unlikely to agree to any Article 50 extension unless there is a clear purpose to it, other than just buying time for yet more turmoil and negotiation. Secondly, as mentioned already, the EU will be very reluctant indeed to agree any extension beyond 2nd July 2019 because of the consequences for the European Parliament elections. But, thirdly, quite apart from what the EU as a whole may have concerns about, each individual Member State may have demands of its own. As reported in the Financial Times on 1st February: “The Spanish are gearing up for a Gibraltar fight when there is an extension request,” said one senior EU diplomat. “It could be dangerous.” And Germany also could have its demands. When my colleague Dr Gunnar Beck and I gave evidence in Berlin to the European Union Committee of the Bundestag, the subject of a possible Article 50 extension was raised by a number of the German legal experts giving evidence to the Committee. First, it was the general view that there would be great difficulties in extending it by more than a couple of months, because that would mean that the May 2019 European Parliament elections would need to be held in the UK. None of the German legal experts could think of a convincing way round this problem, since the election of MEPs in each Member State is mandated by the European treaties. However, one of the German experts made an important point. He pointed out that the UK Government is using the fact that there is no mechanism to make the UK pay the ‘divorce bill’ unless a Withdrawal Agreement is ratified as a negotiating lever. He advised the Committee that Germany should require, as a precondition of agreeing to any Article 50 extension, that the UK should agree unconditionally to abide by the obligations to pay money into the EU budget which are set out in Part Five of the Withdrawal Agreement, and to submitting to the jurisdiction of the ECJ to set the amount of these payments, regardless of whether or not a Withdrawal Agreement was subsequently ratified. One does not know whether the German Government will take up this suggestion, but it would be quite logical for it to do so. Germany will end up paying the lion’s share of the shortfall in the EU budget caused by the UK’s departure. Under the draft Withdrawal Agreement, the UK would have to pay a sum which has been widely estimated at £39 billion, but in fact is likely to end up considerably higher, particularly since Theresa May caved in to the EU’s demand that the ECJ should be given jurisdiction to decide the amount instead of a neutral international tribunal. Under international law, the UK would have some legal obligations, but they would be very much lower (for background on this, see what I and Charlie Elphicke MP wrote here on the EU’s financial claims). So taking advantage of the UK’s moment of weakness when it supplicates for an Article 50 extension, and taking the chance to lock in the EU’s legal entitlement to this enhanced sum come what may, would be quite the logical thing for Germany to insist on. This illustrates a wider point about any application to extend Article 50. By asking for a favour when up against the clock, the UK would once again put itself in a very weak negotiating position, where it would be subject to being blackmailed for further concessions. It would also let the EU off the hook and remove the negotiation pressure on the EU to revise the terms of the Withdrawal Agreement. Asking for an Article 50 extension would be a terrible, terrible idea.
