Enlargement safeguards will work only if candidates can see the trigger

This is an Opinion piece from Plumb Line, EM Governance Review's analysis, explainer and opinion column. It argues for a position on a live regulatory debate; the facts it rests on are linked.

The European Union has spent years asking candidates to prove they are ready. It is now writing the rules for what happens if a new member stops being ready after it joins. That is the right question. The answer the Commission has put on the table is mostly right as well, but it will only change behaviour in Kyiv, Chisinau, Tirana and Podgorica if the conditions for using it are written down as precisely as the conditions for getting in.

What is proposed

In its package on pre-enlargement policy reviews, published on 6 October, the Commission proposes "a common framework" of safeguards for future accession treaties, according to the text published by the EU delegation in Moldova. The period during which sectoral safeguards in the economy, the internal market and justice and home affairs can be activated after accession "would be significantly extended". A new institutional safeguard "would address serious breaches of Article 2 TEU values and the principle of sincere cooperation", and "in the most serious cases, measures could include the suspension of Council voting rights". A new member could also commit, for a limited period, not to block future enlargements because of bilateral disputes.

The package goes further on the EU's own decision-making. The Commission suggests qualified majority voting "for the opening of the negotiating clusters and other intermediary decisions in accession negotiations", will keep pressing for passerelle clauses to end unanimity in areas such as sanctions and tax fraud, and proposes to explore "a more effective handling of Article 7 procedures, including possible timeframes". Gradual integration into selected EU policies before membership would remain "merit-based, conditional and reversible". For Ukraine, targeted arrangements "should significantly limit financial support and market access for sensitive agricultural products".

Leaders took the debate on 16 October. Their conclusions describe enlargement as "a geostrategic investment in peace, security, stability and prosperity", say that "both future Member States and the EU need to be ready at the time of accession", take note of the Commission's communication and ask the Council "to analyse all strands", the conclusions show. They did not endorse the safeguards or the move to majority voting.

Why the design matters

The safeguard idea responds to a real failure. The existing tools for a member state that backslides after accession are slow; the Commission's own proposal to look at "possible timeframes" for Article 7 procedures is an admission of that. A clause written into each accession treaty, with a longer activation window, is a more credible deterrent than a general procedure that has to be assembled case by case.

The risk lies in the drafting. A safeguard that can be triggered by a political judgement in Brussels, on criteria that the acceding state cannot test in advance, turns membership into probation without an end date. For governments that have to sell painful reforms at home, that is a weak offer. For investors in the candidate countries, who price the accession premium into long-term assets, an open-ended political trigger is a source of risk rather than reassurance.

Three features would make the safeguard credible on both sides. First, the triggers should be tied to findings the EU already produces, the annual Rule of Law Report and the enlargement reports, which the Commission says will remain "the main monitoring tools". A safeguard that can only be activated after a documented finding in those reports gives the new member a visible warning and a chance to correct. Second, each sectoral safeguard needs a fixed window in years, written into the treaty, rather than a window that can be extended by later decision. Third, the institutional safeguard, the one that can suspend Council votes, should follow a graduated logic: a finding, a proportionate measure, and a defined route to lifting it.

The test case is already running

On 13 October the Council opened accession negotiations with Ukraine on the cluster covering the internal market, competitiveness and inclusive growth, its press release shows, and Moldova started talks on the same cluster, according to the Council. The same day Albania provisionally closed the chapter on enterprise and industrial policy, the Council said, and the European Council welcomed work on drafting Montenegro's accession treaty. The safeguards will be written into these treaties first. Montenegro's will be the template.

That gives the EU a short window to settle the design before it is negotiated country by country under time pressure. The Commission says it will present indicative roadmaps for Montenegro, Albania, Moldova and Ukraine in the 2026 enlargement package. Those roadmaps are the place to state, for each candidate, which findings would trigger which safeguard and for how long.

Plumb Line's view is that the safeguard clause should be adopted, that majority voting for opening clusters should follow, and that both should come with published triggers and fixed windows. A Union that asks candidates for predictability in their courts and regulators should offer the same predictability in its own conditions.
