Greece’s Foreign Minister Giorgos Gerapetritis says the 2019 Turkey-Libya maritime boundaries memorandum remains legally ineffective, after Libya’s House of Representatives ratified the agreement. Greece, Egypt, Cyprus, Bahrain, the United Arab Emirates and the European Union jointly warned that the move could affect regional stability and the rights of other coastal states.
The statement places the dispute within the framework of international maritime law, particularly the United Nations Convention on the Law of the Sea (UNCLOS). It also underlines the continuing political sensitivity of maritime jurisdiction in the eastern Mediterranean.
What happened in the Turkey-Libya maritime dispute?
Libya’s House of Representatives recently ratified the 2019 memorandum signed between Turkey and Libya on the delimitation of maritime jurisdiction areas. The agreement has long been opposed by Greece and Cyprus, which argue that it does not properly account for the rights and geography of other coastal states, including islands.
Responding to the ratification, Gerapetritis issued a joint statement on behalf of the participating countries and the European Union. He said the memorandum was “null and void and without legal effect” and could not provide a lawful basis for establishing maritime zones or create legal consequences for third countries.
The statement was presented as a response to the Libyan parliamentary decision, rather than as a new EU legislative measure. It therefore does not create a new European Union law or alter the formal legal process governing maritime-boundary disputes.
Why Greece says the memorandum has no legal effect
Greece’s position is that the 2019 arrangement conflicts with international law and cannot override the rights of other states bordering the Mediterranean. The joint statement referred specifically to UNCLOS and customary international law as the applicable frameworks for maritime delimitation.
Those principles are important because maritime zones can affect access to resources, navigation, security arrangements and the scope of coastal states’ jurisdiction. The signatories argued that agreements between two countries should not prejudice the lawful rights of third states.
The statement also stressed the importance of islands under the law of the sea. Greece has repeatedly maintained that islands should be taken into account when maritime zones are determined, while Turkey disputes aspects of that interpretation in the eastern Mediterranean.
The concern over precedent
Gerapetritis warned that accepting bilateral agreements that disregard the relevant international rules could create a wider precedent. In the signatories’ view, such an approach could weaken legal certainty and make the peaceful settlement of maritime disputes more difficult.
The argument is not limited to the immediate disagreement between Greece, Turkey and Libya. It reflects a broader concern about whether bilateral arrangements can affect the maritime rights of countries that were not parties to the original agreement.
What the joint statement says about regional security
The signatories described the Libyan parliamentary ratification as raising serious concerns for security and stability in the region. The eastern Mediterranean is already affected by overlapping political, diplomatic and energy interests involving several countries.
The statement called for international law and good-neighbourly relations to guide Libya’s political transition and its dealings with neighbouring countries. It also reaffirmed support for the reunification of Libya’s institutions and for a united and prosperous Libya.
According to the statement, a stable Libya that participates in regional cooperation is important to peace and security across the Mediterranean. This links the maritime dispute to wider concerns about Libya’s political development and its relations with surrounding states.
What does this mean for the European Union?
The European Union was among the parties associated with the joint statement. However, the statement itself should not be confused with a binding EU decision, a European Commission proposal or a new measure adopted by the Council of the European Union.
Its significance is diplomatic and political: it shows that the EU is aligned with the position that maritime arrangements should respect international law and should not undermine the rights of third countries. The statement also places the issue within wider European affairs concerning Mediterranean security, regional stability and relations with neighbouring states.
Further legal or diplomatic developments would depend on actions by the countries involved, Libya’s institutions and any relevant international bodies. The statement does not itself settle the maritime-boundary dispute.
What happens next?
The immediate disagreement is likely to remain a matter of diplomatic and legal contention. The key issues include:
- How Libya’s institutions proceed with the 2019 memorandum.
- Whether Turkey or Libya takes further steps to implement or rely on the arrangement.
- How Greece, Cyprus and other affected states respond through diplomatic or legal channels.
- Whether international institutions become involved in addressing competing maritime claims.
No new maritime boundary has been established through the joint statement, and the statement does not provide a final judicial ruling on the validity of the memorandum. Any authoritative legal determination would require the appropriate international or national legal process.
Why the development matters
The dispute matters because maritime boundaries can influence state jurisdiction, energy exploration, security cooperation and relations between neighbouring countries. It also highlights the limits of bilateral agreements when other coastal states argue that their rights have been overlooked.
For the EU, the issue is part of a broader Mediterranean policy environment involving diplomacy, international law and regional security. For Ireland, the development is not a direct change to domestic law, but it remains relevant as an example of the EU’s foreign-policy engagement and its support for rules-based dispute settlement.
Conclusion
Greece and its partners have rejected the legal effect of the 2019 Turkey-Libya maritime memorandum following its ratification by Libya’s House of Representatives. The immediate consequence is renewed diplomatic tension, not a settled maritime boundary. The next stage will depend on further action by Libya, Turkey, Greece, Cyprus and other regional actors, as well as any legal processes that may follow.
