A Supreme Administrative Court ruling over the 2015 transfer of nearly EUR2bn of senior Novo Banco bonds back to BES could shape pending investor claims and leaves bondholders with narrow, difficult appeal routes

Portugal’s highest administrative court has delivered the toughest setback yet for Novo Banco bondholders, rejecting a pilot appeal over Banco de Portugal’s decision to move almost EUR2bn of senior bonds back to the failed Banco Espirito Santo.

The financial loss is only part of the story. More damaging for investors, the court also refused to send the case to the Court of Justice of the European Union. That means one of Europe’s most contentious post-crisis bank-resolution disputes remains, for now, inside Portugal’s administrative courts.

The 7 May 2026 judgment, in case 775/16.5BELSB.SA1, concerned a claim brought by Weiss Multi-Strategy Adviser LLC, OGI Associates LLC and Weiss Insurance Partners (Cayman) Ltd against Banco de Portugal, Novo Banco, BES and the Resolution Fund. It was one of the pilot cases challenging Banco de Portugal’s 29 December 2015 retransfer decision.

For readers new to the saga, the mechanics are simple. BES was resolved in August 2014. Novo Banco was created as a bridge bank to receive selected assets and liabilities from the collapsed lender. Seventeen months later, Banco de Portugal decided that five series of senior bonds should be taken out of Novo Banco and sent back to BES, now an insolvent shell. The bonds had a nominal amount of EUR1.94bn and a balance-sheet value of about EUR1.99bn.

That retransfer is the decision bondholders have spent years trying to unwind. Antigua.news wrote last July about the long wait for justice in the Novo Banco litigation. In January, we reported that the Lisbon District Administrative Court had upheld the retransfer at first instance. The Supreme Administrative Court has now reached the same result at a higher level – and with wider consequences.

The ruling is not formally binding on every pending Novo Banco/BES case. But pilot cases are not ordinary cases. Their real power lies in the template they create. For other investors with materially similar claims, the judgment is a warning that Portugal’s top administrative judges may already have chosen their answer.

A 2015 retransfer judged by 2014 law

The court’s core move was to decide the case through a timeline. Investors argued that the 2015 retransfer should be judged under the 2015 version of Portugal’s banking resolution regime, adopted by Law 23-A/2015 to transpose the EU Bank Recovery and Resolution Directive, or BRRD. In their view, that later framework imposed tighter limits on retransfers and required clearer advance identification of the assets or liabilities that could be moved.

The Supreme Administrative Court disagreed. It treated the December 2015 retransfer not as a fresh, stand-alone administrative act, but as a continuation of the original 3 August 2014 BES resolution. Because Novo Banco had been created in 2014, and because the original resolution said Banco de Portugal could transfer or retransfer assets and liabilities between BES and Novo Banco “at any time”, the court held that the applicable regime was the 2014 version of the RGICSF, not the 2015 framework.

That conclusion is decisive. It pulls a December 2015 decision back into the legal world of August 2014. It also prevents investors from using the later BRRD-transposition rules as the operative standard for the retransfer.

The court went further. Even if the 2015 regime did apply, it said, the outcome would not change. The general reservation in the 2014 resolution was enough, in its view, to authorise later retransfers. Investors wanted the law to require more: specific assets, specific liabilities, clearer conditions and a narrower time window. The court saw no such requirement.

No trip to Luxembourg

For bondholders, the refusal to make a preliminary reference to the CJEU may be the most important part of the judgment. Under Article 267 TFEU, national courts can ask the CJEU to interpret EU law. Courts of last instance may have a duty to do so when a genuine and necessary question of EU law remains unresolved.

But private investors cannot directly appeal a national judgment to the CJEU. They can argue EU law before a national judge. They can ask that judge to send questions to Luxembourg. What they cannot do is force the door open themselves. If the national court refuses to refer, the EU-law question can die domestically.

The Supreme Administrative Court said a reference was unnecessary. It relied on BPC Lux 2, a 2022 CJEU judgment arising from the BES resolution, and Novo Banco and Others, a 2024 CJEU judgment in joined Spanish references concerning the recognition of bank reorganisation measures and the retransfer of liabilities.

In the Portuguese court’s reading, those cases have already settled the essentials: the BRRD does not govern this retransfer; the relevant European framework is instead Directive 2001/24/EC on the reorganisation and winding up of credit institutions; a retransfer back to BES is not automatically prohibited by EU law; and proportionality is primarily for national courts to assess.

That is the uncomfortable point. A dispute with obvious cross-border consequences – and a holder base that investors say was overwhelmingly international – has been kept out of Luxembourg. The CJEU remains present only through the Portuguese court’s reading of past CJEU judgments.

What the court accepted

The rest of the ruling gives Banco de Portugal a broad margin of appreciation. The court accepted the central-bank narrative that the retransfer was needed because BES assets transferred to Novo Banco had been overvalued, leaving the bridge bank with liabilities that exceeded the true value of the corresponding assets.

It also rejected the bondholders’ pari passu argument. In ordinary terms, investors said senior creditors of the same class should be treated equally. The court answered that bank resolution is different: it requires equitable treatment, not strict equality. On that basis, Banco de Portugal could treat creditors in the same broad class differently if the distinction served the public interest, was proportionate and did not amount to nationality discrimination.

That formula matters for markets. It means legal ranking is not the whole story. The type of instrument, the size of denomination and the perceived sophistication of the holder can all become relevant when authorities decide who bears losses. In this case, the bonds selected for retransfer were large-denomination instruments, issued in EUR100,000 units and placed with qualified or institutional investors.

The court was equally unmoved by the nationality argument. Investors said the selected bonds were largely held by foreign institutional investors and that the measure therefore had a discriminatory effect. The court said the criterion was neutral: it targeted instruments, not passports. It also stressed that the appellants in this case were based in the United States and the Cayman Islands, and that the evidentiary record did not prove the kind of indirect discrimination alleged.

On proportionality and legitimate expectations, the court again sided with the regulator. It accepted that the retransfer was necessary to restore the balance of Novo Banco’s balance sheet and protect financial stability. It also held that professional investors could not credibly claim surprise, because the original 2014 resolution and subsequent Novo Banco materials referred to the possibility of later retransfers.

There is a formal logic to that reasoning. There is also a market objection. Banco de Portugal spent months trying to stabilise Novo Banco, restore confidence and sell the bridge bank. Investors say they bought and held in that context. The court’s answer is that sophisticated investors should have read the legal footnote.

The risk for pending cases

The judgment is not formally binding on every pending Novo Banco/BES case. But that may matter less than it sounds. Pilot cases exist because courts intend them to guide parallel litigation. This ruling now creates a strong gravitational pull for other cases reaching the Supreme Administrative Court or still moving through Portugal’s administrative system.

The risks are obvious. First, the 2014-law theory may become the default answer to every attempt to invoke the 2015 RGICSF or the BRRD. Second, the “equitable not equal” formula may neutralise pari passu claims. Third, the refusal to send questions to Luxembourg may embolden other courts to treat EU law as already settled. Fourth, the court’s treatment of indirect discrimination raises the evidentiary bar: investors will need more than the international profile of the affected instruments.

For claimants whose appeals are materially identical, the message is stark. Unless they can distinguish their facts, sharpen the constitutional questions or present a materially different EU-law issue, the Portuguese administrative judiciary may now have an off-the-shelf template for dismissal.

What remedies remain?

The most immediate domestic remedy is a constitutional appeal to the Portuguese Constitutional Court. Article 280 of the Portuguese Constitution allows appeals on concrete constitutional-review issues, and the Constitutional Court Law provides that such appeals are normally filed within 10 days. But this is not a third appeal on the merits. It requires a properly preserved normative issue: for example, whether Article 145-H(5) of the 2014 RGICSF, as interpreted by the Supreme Administrative Court, gives Banco de Portugal an insufficiently determinate power to reallocate private rights; or whether such an interpretation violates legality, legal certainty, property rights, equality or effective judicial protection.

That route has the best immediate procedural logic, but the chances are moderate at best. The Constitutional Court will not reweigh the evidence, reassess proportionality in the abstract, or decide whether the Supreme Administrative Court was commercially fair. Investors would need to isolate a constitutional defect in the norm as applied, not merely dissatisfaction with the outcome.

A request for correction, nullity or reform before the Supreme Administrative Court may also be considered, but its practical prospects appear low. The judgment is long and deliberately comprehensive. The court addressed the main grounds and devoted extensive reasoning to the refusal of the CJEU reference. A technical procedural defect may exist, but it would need to be specific and serious.

Strasbourg is another route, but not an easy one. An application to the European Court of Human Rights could invoke excessive length of proceedings, property rights and the fairness of a final-instance refusal to refer EU-law questions. Since 1 February 2022, the time limit for applications to the court has been four months from the final domestic decision.

A European market trapped in domestic procedure

The larger criticism is institutional. European banking law promises a common market, common rules and a common court to interpret them. But investors cannot directly ask the CJEU to decide whether the Portuguese courts have correctly understood EU law. If the national court refuses to refer, the EU-law door can close before the investor ever reaches Luxembourg.

That architecture may be tolerable in routine disputes. It is much harder to defend in a case of this scale: a post-crisis bank resolution, a retroactive retransfer, senior creditors selected for losses, cross-border institutional investors and a decade of litigation.

From the investor’s perspective, the danger is a form of “home-made justice”: a tailor-made, domestic version of European legality, produced inside a Portuguese judicial grid that has already shown itself, at least in administrative litigation, to be painfully slow and commercially inefficient. This is not an accusation of corruption. It is a critique of design. If a supranational capital market leaves foreign investors dependent on national courts that may decline to ask the supranational court, European legal protection becomes contingent rather than uniform.

The Credit Suisse parallel

Novo Banco is not an isolated warning. Europe is living through a period of unusual uncertainty for bank bondholders. In Switzerland, FINMA ordered Credit Suisse to write down its AT1 instruments during the 2023 UBS rescue. The Swiss Federal Administrative Court later said the write-off lacked legal basis and revoked FINMA’s decree in a partial decision, while FINMA has said it will appeal to the Swiss Federal Supreme Court. Antigua.news has followed that dispute as part of its wider Credit Suisse AT1 coverage.

The parallels are not perfect: AT1 instruments are designed to absorb losses, whereas the Novo Banco dispute concerns senior bonds reallocated between a bridge bank and a bad bank. But the market lesson is similar. Authorities can make value-destroying decisions in a weekend; investors may then spend years, sometimes a decade, trying to test legality.

That asymmetry is corrosive. Bank resolution needs speed. Justice does too. If courts cannot deliver timely and independent scrutiny, resolution law becomes less a system of rules than a promise to explain later why the state had no choice.

The final word – for now

The Supreme Administrative Court’s ruling may not end the Novo Banco bondholder saga. Constitutional arguments, Strasbourg claims, compensation routes and parallel cases may still move. But the legal centre of gravity has shifted.

Portugal’s highest administrative court has now endorsed the core architecture of the 2015 retransfer: 2014 law governs; the 2014 reservation of retransfer power was sufficient; strict pari passu equality does not control; nationality discrimination was not proved; and Luxembourg need not be asked again.

For Banco de Portugal, that is a major victory. For investors, it is a warning that the most important battle may no longer be only over the bonds. It is over whether European financial justice can be made fast enough, open enough and supranational enough to protect the people whose money bank-resolution law is supposed to discipline.
