Shareholder Disputes under Swiss Law

Swiss stock corporation law provides a graded suite of remedies for shareholders who believe the company is being mismanaged, the board is acting against the company’s interest, or a controlling shareholder is treating them inequitably. The suite — the information right, the special investigation, the challenge of resolutions, the dissolution action for cause, and the liability action — is structured around a fundamental premise of Swiss corporate law: that internal corporate remedies should be exhausted before external coercion; and that each successive remedy requires a heavier procedural and evidentiary foundation. A board that understands where on this ladder a given dispute sits can, almost always, manage it to a resolution that preserves both the company’s interest and the board’s own defensibility.

1. The remedy architecture

Five remedies form the backbone of the system, each governed by a cluster of OR provisions and each with a distinct procedural posture.

The information right — Art. 697 OR. A shareholder is entitled to request information from the board about the company’s affairs, and — subject to stricter conditions — inspection of books and records. The right is exercised at the general meeting, and where denied can be enforced by court action within one month. The information right is the gateway remedy; most shareholder disputes that reach litigation begin with an information request that was refused or inadequately answered.

The special investigation — Art. 697c–697g OR. Where the information right does not produce the answers a shareholder needs to exercise their rights, they may — acting alone or jointly with others holding the threshold share — first move at the general meeting (Art. 697c OR) and, on rejection, petition the court (Art. 697d OR) for the appointment of an independent investigator to examine specified questions of fact about the company’s conduct. The threshold, the subject-matter limits, and the court’s discretion were all materially affected by the 2023 revision of Swiss stock corporation law; the mechanism is now more accessible to minority shareholders than under the prior regime, and the post-2023 case law applying the revised framework is still being built. The 2023 revision also introduced an enhanced inspection right under Art. 697a OR (5 per cent threshold for inspection of books and records), which sits below the special-investigation rung on the ladder.

The challenge of resolutions — Art. 706, 706a, 706b OR. Shareholders may challenge resolutions of the general meeting that violate the law or the articles of association, through the Anfechtungsklage. The challenge must be brought within two months of the general meeting (Art. 706a para. 1 OR), the period being substantive and strict. Board resolutions are not, as a matter of general Swiss corporate law, challengeable by the same mechanism — with narrow exceptions — though they may be attacked indirectly through the liability action or by challenging the general meeting resolution that approved them. Resolutions that are null and void (Art. 706b OR) — for example, resolutions that strip inalienable shareholder rights — are subject to declaration of nullity without time limit.

The dissolution action for cause — Art. 736 para. 1 ch. 4 OR. Shareholders holding at least ten per cent of the share capital may petition the court to dissolve the company for important cause. In practice, courts treat the dissolution remedy as one of last resort and may, in the exercise of discretion, order alternative relief — most significantly, a court-ordered buyout of the minority’s shares at their real value. The dissolution action is accordingly, in its practical operation, a minority-oppression remedy by another name. The Swiss Federal Supreme Court has consistently treated the court-ordered buy-out at real value as the ordinary alternative to dissolution in the closely-held-company setting, with valuation by court-appointed expert where the parties cannot agree.

The liability action — Art. 754–760 OR. The company’s shareholders — and, in bankruptcy, creditors — may sue the directors for damage caused to the company through breach of duty. The liability action is treated in the Director Duties article at section 5; its interaction with shareholder dispute strategy is addressed below in section 5.

2. Information requests — the first move

Most shareholder disputes that reach the courts begin with an information request that was refused, partially answered, or answered in a manner the shareholder considers inadequate. The board’s response to this first move matters disproportionately.

Art. 697 al. 1 OR establishes the right; Art. 697 al. 4 OR restricts it — the board may refuse where disclosure would endanger business secrets or other legitimate interests of the company. The line between legitimate refusal and obstruction is, in Swiss practice, a narrow one. Three patterns recur.

Over-refusal. A board that treats the information right as adversarial and refuses requests on boilerplate grounds of “business secrets” without calibration to the specific information asked invites the court to order disclosure and, in doing so, to frame the underlying matter in terms more hostile to the board than an early, calibrated response would have done.

Under-refusal. A board that discloses information it should have protected — sensitive commercial information to a shareholder who is effectively a competitor, privileged material to a shareholder in prospective litigation against the company — breaches a duty in the opposite direction. Disclosure discipline is a dimension of the duty of care.

Inconsistency. Information provided to some shareholders and withheld from others, particularly where the difference tracks alignment with the incumbent board, breaches the equal-treatment principle of Art. 717 al. 2 OR. Where information has been given voluntarily to one shareholder group, it is difficult to refuse the same information to another on business-secret grounds.

The Independent Oversight discipline is particularly valuable at this stage: when the request implicates matters in which a director’s conduct is under scrutiny, the decision on the response is one the affected director cannot credibly make or influence.

3. The special investigation — procedure and leverage

The special investigation — Sonderuntersuchung, examen spécial — is the remedy by which a shareholder obtains a court-appointed independent fact-finder. It is initiated by a shareholder motion at the general meeting; rejection (or failure of the meeting to decide) opens the path to a court petition.

Thresholds. Following the 2023 revision (Art. 697d para. 1 OR), the threshold for petitioning the court was lowered: for listed companies, shareholders holding at least five per cent of the share capital or voting rights; for non-listed companies, shareholders holding at least ten per cent of the share capital or voting rights. The petition must be made within three months of the general meeting’s rejection. Prior to the revision the thresholds were materially higher and the remedy was in consequence available almost exclusively to large minority blocks.

Subject matter. The petition must specify concrete questions of fact the investigator is to examine. The court will not authorise a fishing expedition; nor will it authorise an investigation into matters the shareholder could have addressed through the ordinary information right. The petitioner must demonstrate that there are sufficient indications of breach of duty or violation of the law or articles and that the information is necessary to exercise shareholder rights.

Effect. The investigation produces a written report accessible to all shareholders. In practice, the process of investigation — the interviews, the document requests, the investigator’s access to privileged spaces of the company — is often at least as consequential as the report itself. Boards facing a plausible special-investigation petition frequently settle the underlying dispute on concessions they would not otherwise have made, because the process itself is operationally disruptive.

Strategy. For the board facing a special- investigation petition, the discipline is not to resist reflexively. A targeted, time-limited investigation into a narrow set of facts is often preferable to a broader fight over whether the threshold is met, the questions are admissible, or the subject-matter is ripe; resisting substance on procedural grounds tends to enlarge the scope of what the court eventually authorises.

4. Challenge of resolutions — the two-month window

The Anfechtungsklage under Art. 706 OR is a fixed-window remedy. The resolution must be challenged within two months of the general meeting (Art. 706a al. 1 OR), failing which the challenge is precluded. The remedy is available to any shareholder who did not vote in favour of the resolution and to the board itself against a resolution of the general meeting.

Three categories of defect are most frequently pleaded.

Procedural defects. Convocation irregularities, inadequate notice of agenda items, deficient disclosure of proposed resolutions, denial of information rights at the meeting itself. Procedural defects are the most commonly litigated and — where they bite — the most readily proved.

Violation of the articles or the law. Resolutions that exceed the general meeting’s competence, that alter rights in a way the articles do not permit, or that contravene a specific statutory provision are challengeable on this ground.

Abuse of majority. A resolution that is formally lawful but pursued against the company’s interest in order to favour the controlling shareholder, or that disadvantages minority shareholders without justification, engages Art. 706 al. 2 ch. 3 OR — the resolution can be annulled for unequal treatment or prejudice to the company. The abuse-of-majority head is narrowly construed by Swiss courts but is the remedy on which controlling-shareholder disputes most frequently turn.

Nullity under Art. 706b OR is a separate and more serious defect — a resolution that strips inalienable shareholder rights, that violates fundamental Swiss company-law principles, or that oversteps the limits of majority rule — and can be invoked without the two-month time bar. Nullity pleas are rare but occasionally decisive.

5. Dissolution, buy-out, and the liability action

Three end-state remedies deserve separate treatment.

Dissolution for cause. Under Art. 736 ch. 4 OR, shareholders holding at least ten per cent of the share capital may seek judicial dissolution for important cause. Persistent minority oppression, systematic breach of shareholder rights, and deadlock where the company can no longer pursue its purpose are typical grounds. The court has wide discretion to order alternative relief; in practice, the most common alternative is a court-ordered buy-out of the petitioning minority at their shares' real value — a remedy that is, substantively, the Swiss equivalent of an oppression buy-out order in common-law systems.

The liability action. Shareholders may bring an action under Art. 754 OR for damage caused to the company by director breach of duty; recovery runs to the company, not to the shareholder. The mechanism sits awkwardly alongside shareholder-dispute strategy because the economic incentives of a minority shareholder who has not yet been bought out are not well aligned with a recovery paid to the company. In bankruptcy, however, the liability action becomes the principal creditor remedy, typically vehiculated through the cession mechanism of Art. 260 SchKG; the Papierschlamm commentary illustrates the pattern.

Arbitration. The 2023 revision introduced a statutory basis for arbitration clauses in the articles of association of Swiss stock corporations (Art. 697n OR), which bind shareholders, the company, and the organs for intracorporate disputes. Where an arbitration clause is in force, most of the remedies above are directed to the arbitral tribunal rather than the ordinary courts, with procedural consequences — on confidentiality, on the standard of review, on the interaction with public-order-protected shareholder rights — that require separate analysis and are still being worked out in post-2023 practice.

6. What this means for boards

Four practical points follow.

Read the ladder. Shareholder disputes arrive at a specific rung on the remedy ladder. A board that responds to an information request as if it were already litigation escalates the matter; a board that responds to a liability threat as if it were merely an information request under- responds. The competent first response is to identify the specific remedy the shareholder is invoking — or might invoke if the current step fails — and to structure the company’s response to that remedy’s doctrinal architecture.

Answer the question actually asked. The most common failure in shareholder-dispute management is responding to the request the board wishes had been made rather than the one that was. Where the information requested is genuinely within the legitimate scope of the information right, providing it — on the terms and with the caveats appropriate to the business-secret exception — is almost always less costly than the litigation that follows refusal.

Treat the 2-month window as non-negotiable. The Anfechtungsklage window closes whether or not the dispute appears to be heating up. Where there is any indication a shareholder will challenge a general-meeting resolution, the board should not assume the shareholder will observe an internal resolution timeline; it should assume the window will be used.

Preserve the record. Every shareholder dispute that reaches litigation turns, at some point, on what the board did, what it knew, what it considered, and what it decided. The Litigation Readiness discipline applies with particular force to the board resolutions, minutes, committee deliberations, and communications relating to the dispute itself — including the decision-making about how to respond to it.
