European Court of Justice Rules Nord Stream 2 Must Comply With EU Gas Regulations

On November 5, 2026, the Court of Justice of the European Union definitively rejected an appeal by the Gazprom-owned operator of the Nord Stream 2 pipeline. The ruling cements regulations that force the dormant Russian gas link to comply with strict internal market rules. The decision marks the end of a seven-year legal battle over the infrastructure.[1][2]

The Luxembourg-based court dismissed the challenge brought by Nord Stream 2 AG in its entirety. The Swiss-based company had sought to overturn a 2019 directive that extended European Union gas market rules to offshore pipelines entering the bloc from non-member states. The contested provisions will now remain permanently in force.[2][3]

Under the 2019 Gas Directive amendments, pipelines connecting member states to third countries must adhere to ownership unbundling. This mandate requires that the entity supplying the natural gas cannot also control the transmission infrastructure. The rules additionally require regulated third-party access and strict tariff transparency.[2][4]

The legislative changes were highly controversial when introduced, as they directly impacted the business model of the Russian state-backed energy giant. Prior to 2019, the European Union’s internal market rules primarily governed pipelines located entirely within the borders of member states, leaving offshore import routes in a regulatory gray area.[1][2]

The Legal Arguments

Nord Stream 2 AG argued that the legislation was specifically designed to obstruct their 55 billion cubic meter per year project. The company claimed it was entitled to a derogation or financial compensation, noting that the pipeline was already under construction when the European Union altered the regulatory landscape.[1][2]

The operator maintained that the 2019 legislation was effectively designed to prevent or complicate the pipeline project rather than achieve the bloc's stated internal-market objectives. They argued that the targeted nature of the rules violated principles of legal certainty, equal treatment, and the protection of legitimate investor expectations.[2][3]

The Court of Justice upheld a November 27, 2024, General Court ruling, finding that European Union institutions had never given the company precise or unconditional assurances that the pipeline would remain exempt. The judges noted that indications of impending regulatory changes had existed since at least 2010.[1][3]

The court explicitly rejected the argument that Nord Stream 2 AG's specific corporate structure should exempt it from the unbundling mandate. Allowing such an exemption, the judges wrote in their decision, would deprive the unbundling obligation of its practical effectiveness and undermine the broader market framework.[3][4]

A central point of contention in Case C-118/25 P was Article 49a of the directive, which allowed member states to grant waivers to pipelines completed before May 23, 2019. Because the Nord Stream 2 project was not finished by that cutoff date, it missed the window for a derogation that could have lasted up to 20 years.[1][2]

Closing the Regulatory Gap

The ruling affirmed that the European Union possessed legitimate authority to apply internal market principles to import pipelines. The court concluded that the measures actively support competition, security of supply, and consistent regulation across the European gas market, closing a significant historical gap in offshore jurisdiction.[2][4]

By upholding the directive, the court reinforced the requirement that third-party access encompasses more than just physical connections. The judges noted that it also guarantees the right for competing suppliers to utilize transport capacity under fair and transparent conditions, preventing a single state-backed entity from monopolizing an import route.[2][3]

Nord Stream 2 AG had also argued that a July 2022 procedural ruling by the top court had already established that the company faced unequal treatment compared to other pipeline operators. The Court of Justice dismissed this interpretation on Thursday, clarifying that the 2022 decision dealt strictly with the admissibility of the lawsuit, not its merits.[1][3]

The top court wrote on Thursday that it was clear from reading the 2022 judgment that the Court of Justice in no way examined whether there was any difference in treatment between the appellant and the other pipeline operators. This clarification dismantled the core of the company's procedural appeal.[1][3]

As part of the final judgment, the court ordered Nord Stream 2 AG to bear its own legal costs. The company must also cover the costs incurred by the European Parliament and the Council of the European Union during the appeal process. Poland and the European Commission, which participated in the proceedings, will bear their own expenses.[2][3]

A Dormant Asset

The definitive legal defeat arrives while the physical infrastructure remains entirely non-operational on the floor of the Baltic Sea. Nord Stream 2 was originally designed to double the capacity of the direct Russian export route to Germany to 110 billion cubic meters annually, but the pipeline never entered commercial service.[1][5]

Germany officially suspended the pipeline's certification process in February 2022, just days before Russia launched its full-scale invasion of Ukraine. That administrative suspension effectively froze the $11 billion project in place, preventing Gazprom from initiating gas flows even before the physical infrastructure was compromised.[1][4]

In September 2022, underwater explosions severely damaged both the Nord Stream 1 and Nord Stream 2 systems near the Danish island of Bornholm. Seismic institutes recorded the blasts, which ruptured the heavy steel and concrete pipes at a depth of roughly 70 to 80 meters, rendering much of the network unusable.[1][4]

The sabotage investigations have spanned multiple European jurisdictions over the past four years. While the physical pipeline remains severed, the legal battle over its regulatory status continued through the European court system, driven by the massive financial investments tied up in the stranded asset.[1][5]

Beyond the physical damage and the lack of German certification, the use of Nord Stream 2 is currently restricted by broad European Union sanctions against Russian energy exports. The bloc has systematically reduced its reliance on Russian natural gas over the past four years, replacing pipeline volumes with global liquefied natural gas shipments.[4][5]

Geopolitical Ramifications

The legal closure of the Nord Stream 2 regulatory dispute mirrors Europe's broader geopolitical pivot away from Russian energy dependence. When the pipeline was first proposed, it faced intense opposition from Eastern European nations and the United States, who warned it would give Moscow undue leverage over the continent's energy security.[1][5]

Estonia, Latvia, Lithuania, and Poland all participated in the appeal proceedings, supporting the European Parliament and the Council in their defense of the 2019 Gas Directive. These nations have long argued that applying strict internal market rules to Russian infrastructure is essential for protecting the sovereignty of neighboring transit countries.[3][5]

The November 5 ruling marks the exhaustion of Nord Stream 2 AG's legal avenues within the European Union judicial system. The decision is final and cannot be appealed further, cementing the regulatory framework for any future third-country pipeline projects that might seek to enter the European market.[3][4]

The regulatory status of the pipeline is now permanently settled, but the physical future of the infrastructure remains unresolved. The Russian government has not indicated if it will attempt to repair the damaged sections, leaving the dormant asset to degrade on the Baltic seabed for the foreseeable future.[1][4]

The Court of Justice's ruling ensures that even if geopolitical conditions shift and the pipeline is eventually repaired, Gazprom cannot operate Nord Stream 2 under its original monopolistic model. Any future operation of the infrastructure will require strict, verifiable compliance with the European Union's unbundled, open-access market rules.[2][3]
