Case-law

The criminal prosecution authority may refuse to seal documents that a bank must keep available for the criminal authorities in accordance with Article 7 AMLA, even if the documents were drawn up by lawyers. This conclusion, reached by the Federal Supreme Court in a ruling dated October 2, 2025—not intended for publication but handed down by five judges—is in line with the trend in case law relating to attorney-client privilege in the context of anti-money laundering (7B_1154/2024). In 2023, the[...]

In a ruling dated September 24, 2025, the Federal Court reiterated that the offense of money laundering requires intent on the part of the perpetrator, at least in the form of eventual intent, and that a single violation of anti-money laundering rules, even a significant one, does not in itself allow such intent to be inferred (6B_1180/2023). The Office of the Attorney General of Switzerland accused a bank employee of opening bank accounts using false customer data and, between 2003[...]

A client's legal action was dismissed on the grounds that she had failed to sufficiently allege the hypothetical scenario of how transactions would have unfolded if the bank had acted in accordance with its contractual obligations. She was suing her Swiss bank to claim reimbursement for a loss resulting from the sale of options on Russian shares (4A_657/2024 of September 1, 2025). In November 2021, a Bahamian company had sold put options on American Depository Receipts (ADRs) of shares in[...]

In its judgment 5A_802/2024 of 28 August 2025 (intended for publication), the Federal Supreme Court ruled on the question of whether freezing orders issued on the basis of the Ordinance on Measures in Connection with the Situation in Ukraine (Ukraine Ordinance) take precedence over enforcement under the Federal Debt Enforcement and Bankruptcy Act (LP). In July 2024, the Zurich Debt Enforcement Office issued a decision suspending enforcement proceedings initiated under the DEBA. The proceedings concerned assets that were also frozen[...]

In a recent judgment intended for publication (judgment 2C_597/2024 of 16 September 2025), the Federal Court confirmed the liquidation of a company that had carried out the activity of an issuing house (see Art. 3 para. 2 aOBVM) (now a securities house, see Art. 44 para. 1 let. c LEFin) without authorisation. Company A, founded in 2015 by C, is active in the sale of subscriptions for recyclable goods. Shortly after the company was founded, C sold 80% of the[...]

In its ruling B-2334/2023 of October 1, 2025, the FAC issued a partial decision overturning FINMA's decision of March 19, 2023, ordering the write-down of hybrid loans recognized as additional tier 1 (AT1) capital. This is an important step in what promises to be a long legal saga. This commentary is an exception to the usual practice regarding the length of the text, given the importance and scope of the judgment. This decision will also be discussed at the 2025[...]

The principle of subsidiarity does not require a state to consult the taxpayer prior to requesting international administrative assistance in tax matters, as long as its domestic law does not require it to do so. This was the ruling of the Federal Court on the legal question of principle raised in case 2C_352/2024 (intended for publication). In 2020, the Israeli Tax Information Exchange Service requested the FTA to provide it with various information (identity of account holders, identity of beneficial[...]

The reasoning behind the Federal Court's decision, handed down following a hearing on 23 May 2025, rejecting a lawsuit brought against the Swiss Confederation in connection with the emergency merger of Credit Suisse Group AG (CS) into UBS Group AG (UBS), has finally been made public (TF, 23.5.2025, 2E_1/2024). The case concerns a couple from Aargau who purchased CS shares on the stock exchange between 10 and 15 March 2023. In the days that followed, the crisis of confidence that[...]

In its ruling 2C_368/2023 of August 6, 2025, handed down by five judges but not intended for publication, the Federal Supreme Court upheld the ban on practicing imposed on the former member of the management of Banca della Svizzera Italiana SA (“BSI”) more than two years after confirming that imposed on the former Head of Legal & Compliance (decision 2C_747/2021, commented on in: Braidi, cdbf.ch/1286). The appellant, former CEO of BSI Singapore Ltd. and member of the management of BSI,[...]

In its ruling ACJC/805/2025 of June 16, 2025, the Court of Justice of the Canton of Geneva ruled on an action for rectification of personal data brought in a banking context. This ruling, which to our knowledge is one of the first published court decisions on such an action in the banking sector, raises questions regarding the application of the revised Federal Act on Data Protection (FADP) in relation to the designation of a beneficial owner. The ruling, which is[...]

Unless expressly stated in the contract, a bank may not terminate a mortgage loan early if, at the time of termination, there are no outstanding payments (4A_599/2024 of May 26, 2025). In August 2021, a bank entered into a mortgage financing agreement with a company and offered a credit line of up to CHF 4,552,500. Article 7 of the agreement stipulates that the debt must be reduced by annual repayments of CHF 52,500, the first of which is due on[...]

In its ruling 4A_493/2024 of 17 June 2025, the Federal Court concluded that employers are required to provide references, in addition to employment certificates, to employees who request them. However, it refrained from setting a specific deadline for doing so, as this will depend on the specific circumstances of each case. The employee had been working for a bank in Zurich since February 2011. The bank dismissed the employee on 2 December 2014 after facing regulatory proceedings in Switzerland, the[...]

‘If money doesn't bring happiness, give it back!’ said Jules Renard. Coluche seized on the phrase with his characteristic wit, and the line struck a chord with people throughout France and Navarre. The following story, sadly familiar, brings us back to this strange paradox. The ruling it generated, TF 4A_577/2024 of 10 July 2025, confirms a carefully reasoned decision by the Zurich Handelsgericht (133 pages) concerning a lack of legitimacy. We apologise in advance to the reader for the length[...]

A possible contractual imbalance in a credit relationship between a bank and its clients does not engage the bank's liability, even if the bank provides its clients with limited information. These are the main findings of judgment 4A_567/2024 of 27 May 2025. In 2013, clients entered into a mortgage loan agreement with a bank for approximately CHF 1.5 million. The interest rate was variable and corresponded to the three-month LIBOR (later SARON) plus a margin. The agreement provided that if[...]

Statements obtained under an obligation to cooperate with FINMA are inadmissible in administrative criminal proceedings brought against an individual for engaging in financial intermediary activities without authorization. This conclusion, reached by the Federal Supreme Court in its judgment 7B_45/2022 of July 21, 2025 (not intended for publication), results in the case being referred back to the Appeals Chamber of the Federal Criminal Court, which will have to re-examine the case without this evidence. The case dates back to 2014, when[...]

When the bank makes a margin call, the client may have very little time to react and provide new funds. In its ruling 4A_389/2024 of May 8, 2025, the Federal Supreme Court reiterated its strict case law on Lombard loans, particularly with regard to clients with extensive financial knowledge and experience. In early April 2019, a client entered into a relationship with a bank. During the account opening process, the client stated that he was an investment expert, had a[...]

A CEO who discloses confidential information to a journalist must compensate his employer for the damage caused, in this case the costs incurred by the communications agency. The fact that other press articles had been published previously does not negate the existence of a causal link (4A_159/2024). A company belonging to a Portuguese banking and financial group dismissed its CEO. It drew his attention to his obligation to maintain professional secrecy. A few years later, rumours began to circulate about[...]

In three judgments 1C_435/2024, 1C_604/2024 (intended for publication) and 1C_610/2024 of 19 May 2025, the Federal Supreme Court ruled to uphold the freeze on bank assets ordered by the Federal Council in 2022 and 2023, the beneficial owners of which are persons belonging to the political entourage of former Ukrainian President Viktor Yanukovych. The assets had initially been seized following a request for international mutual assistance in criminal matters addressed to Switzerland by Ukraine (see TPF, RR.2017.118-121, RR.2017.122, 6 February[...]

The Federal Supreme Court has upheld a ruling by the Geneva Court of Appeal dismissing a liability claim against a bank for mismanagement on the grounds that the allegations were insufficient (ruling 4A_276/2024 of 31 March 2025). The client had held a bank account with the bank in question since the 1960s. In 1995, she inherited EUR 3 million and entered into a management agreement with the bank. At that time, the client's portfolio consisted solely of bonds and cash.[...]

Bank accounts held by a lawyer may contain information protected by professional secrecy, which must not be disclosed to a foreign state in the context of administrative assistance in tax matters. This must be assumed to be the case for client accounts opened using Form R, but it is also possible that other accounts held by the lawyer may contain protected information. These are the principles laid down by the Federal Court in a ruling 2C_116/2023 of 2 May 2025[...]
