If the UK decides to hold a referendum on leaving the EU, also known as “Brexit,” Article 50 of the Treaty on the European Union (TEU) will be a focal point. This article outlines the exit process for member states. While some suggest using Article 50 to renegotiate UK membership, its legal and political limitations make this challenging.

The Details of Article 50

Article 50 allows any EU member state to withdraw according to its constitution. The key provision states that a member state choosing to leave must inform the European Council, which will then create guidelines for negotiating an exit agreement. This agreement outlines the withdrawal process and the future relationship between the EU and the departing state. The European Council, consisting of heads of state, acts on behalf of the EU, and the agreement needs a qualified majority vote and approval from the European Parliament.

Article 50 further states that the UK would leave the EU two years after notifying the European Council, unless a withdrawal agreement is reached with a different timeline or the deadline is extended by unanimous agreement. During this period, the UK cannot participate in certain EU discussions. Article 50 also allows for the UK to rejoin the EU in the future under the same conditions as any other applicant.

Understanding Article 50

Added by the Lisbon Treaty, Article 50 formalizes the right of member states to leave the EU. Although no full member state has left before or after this treaty, Article 50 provides the only legal avenue for doing so. It’s worth noting that a member state can’t be expelled against its will, although membership can be suspended in cases of severe human rights violations, democracy breaches, or disregard for the rule of law.

The crucial aspect of Article 50 is the set timeline for withdrawal. After notifying the EU of its intent to leave, the UK would automatically exit after two years unless a different date is agreed upon in a withdrawal agreement or the deadline is extended unanimously. Whether a withdrawal notification can be reversed is unclear. One could argue that since notification is subject to a member state’s constitution, it follows that they can also rescind it. Conversely, Article 50 only mentions extending the deadline or setting a different date in the withdrawal agreement as reasons for delaying withdrawal, suggesting these are the only possibilities.

Could the UK and the European Council indefinitely postpone the exit by continuously extending the deadline? This is debatable and would likely face legal challenges, especially from those who want the UK to leave. While the treaty doesn’t explicitly forbid it, the purpose of Article 50 suggests that extensions should be temporary, while rejoining after leaving is addressed separately. Had the treaty intended other ways to remain in the EU after notification, it would likely have explicitly stated so.

Misconceptions and Challenges

The legal implications of Article 50 are significant. Using it to force renegotiation of UK membership is not possible. The article clearly states that invoking it will trigger negotiations for exit, not for treaty changes or modifications to EU laws. Although separate agreements might be made after the UK leaves, Article 50 is not designed for renegotiating membership or amending treaties.

Comparing Article 50 to articles outlining treaty amendment processes further highlights this point. Article 50 doesn’t mention amendments, which makes sense, as a departing member state shouldn’t influence laws that no longer apply to it.

Invoking Article 50 for renegotiation purposes would be politically unwise as well. Once triggered, the UK would be compelled to leave within two years unless all remaining members agree to an extension. This gives the remaining member states significant leverage, potentially forcing the UK into accepting unfavorable terms just to remain a member.

This suggests that those proposing Article 50 for renegotiation might actually aim for the UK’s exit. While supporting the UK’s departure is legitimate, advocating for Article 50 to initiate renegotiation appears either naive or potentially deceptive.

Furthermore, Article 50 only covers the withdrawal agreement, not the future relationship between the UK and the EU. Although it acknowledges the future relationship, it doesn’t specify its nature, and there’s no legal obligation for the remaining EU to establish a free trade agreement with the UK.

This is crucial because, unlike the withdrawal agreement, most EU free trade agreements require ratification by all member states, as they often involve regulations beyond EU trade policy. While a trade agreement with the UK is likely, requiring unanimous agreement could complicate matters.

Some argue that the UK could stay in the European Economic Area (EEA) post-Brexit. However, the EEA includes free movement of people, a contentious issue for many Brexit supporters. While the EEA has a safeguard clause to suspend certain obligations, it allows for retaliation. So, if the UK restricted free movement of EU citizens, the EU could retaliate by limiting the UK’s access to its financial market or removing trade preferences for UK exports.

Potential Issues with Bypassing Article 50

Some propose bypassing Article 50 and leaving the EU directly. Legally, the UK parliament could end EU membership by repealing the European Communities Act. However, this is impractical and could harm the UK both politically and economically.

Ignoring Article 50 would leave many practicalities unresolved, like payments from the EU to UK recipients. Even if the UK rejoined the EEA, it would only cover trade and not other issues like the European Arrest Warrant (EAW). Without a transitional plan, which Article 50 provides time for, existing EAWs would be challengeable, potentially leading to the release of detainees and difficulties in extraditing criminals.

Such a “unilateral declaration of independence” would harm the UK’s reputation in future dealings with the EU and other international partners. It would signal a disregard for agreed-upon legal frameworks, making it difficult for the UK to regain trust in international negotiations.

Finally, there’s the suggestion of the UK leaving the EU before the Brexit referendum. This idea is fundamentally undemocratic. The UK’s unwritten constitution now includes a convention of holding referendums for major constitutional changes, like leaving the EU. This must happen before the change, not after.

Leaving the EU without a prior referendum disregards a key aspect of the UK constitution simply for tactical advantage. This approach denies the British public a vote on remaining in the EU or accepting a renegotiated agreement. A Brexit referendum should not be based on such a flawed premise.
