Challenging General Meeting resolutions as a tool for shareholder protection and corporate control
The General Meeting of a Greek société anonyme, or S.A., is not merely a formal corporate body. It is the forum in which some of the most significant developments in a company’s life are decided: share capital increases or reductions, board appointments, approvals of critical transactions, amendments to the articles of association, changes in shareholder balance and resolutions that may determine the company’s strategic direction.
For that reason, defective General Meeting resolutions are one of the most important areas of corporate disputes in Greece. This is not a purely technical issue of company law. In practice, behind a contested General Meeting resolution there may be a shareholder dispute, an attempt to alter the balance of power within the company, a related-party transaction, a challenge to management, or a broader strategic dispute over corporate control.
General Meeting resolutions
Under Article 116 of Greek Law 4548/2018, the General Meeting is the supreme corporate body of a Greek S.A. Its resolutions bind even absent or dissenting shareholders and may affect not only the company’s internal affairs, but also third parties dealing with the company.
A General Meeting resolution forms part of the operation of the legal entity and produces effects that go beyond the relationship between shareholders. This organisational character explains why Greek company law has developed a specific framework for reviewing defective resolutions, mainly through Articles 137, 138 and 139 of Law 4548/2018.
This framework seeks to balance two competing considerations: on the one hand, the protection of shareholders and corporate legality; on the other, transactional certainty and the stability of corporate life.
In a corporate dispute environment, this balance is of considerable practical importance. A resolution may be problematic, but not necessarily easy to overturn.
Voidable, null and non-existent resolutions
Greek law distinguishes between voidable, null and legally non-existent General Meeting resolutions.
Voidability, under Article 137 of Law 4548/2018, is the most common and practically significant form of defect. It covers, among other cases, resolutions adopted in breach of the law or the articles of association, resolutions of a General Meeting that was not lawfully convened or constituted, resolutions adopted without the provision of information that should have been given to shareholders, and resolutions that amount to an abuse of majority power.
Nullity, under Article 138 of Law 4548/2018, concerns more serious defects affecting the resolution. Legal non-existence, under Article 139 of Law 4548/2018, is reserved for cases in which there cannot be said to be a General Meeting resolution with legal existence at all.
This distinction is not theoretical. It directly affects litigation strategy: who has standing, which deadline applies, which claim should be filed, whether interim relief may be available and what evidence must be collected immediately.
Voidability of General Meeting resolutions: the most common field of dispute
Most corporate disputes concerning General Meeting resolutions arise in the context of voidability. This is where issues of lawful notice, constitution of the meeting, quorum, majority, shareholder information rights and abuse of majority power most frequently arise.
However, the court will not annul a resolution for every formal irregularity. It will examine whether the defect was material, whether it affected the shareholder’s participation or vote and whether it infringed the core of the shareholder’s rights. This is where the so-called materiality approach becomes important: not every procedural breach is sufficient to lead to the annulment of a resolution.
This is particularly important when shaping the litigation strategy. A shareholder challenging a resolution must show why the defect is not merely formal, but material. Conversely, the company or the majority defending the resolution must demonstrate that, even if the process was imperfect, the irregularity did not affect the outcome or materially infringe shareholder rights.
The shareholder’s right to information
One of the most frequent areas of conflict is shareholder information. Under Article 137 paragraph 2(a) of Law 4548/2018, a resolution may be voidable if it was adopted without the provision of information that was due, requested by shareholders and related to the matter on which the resolution was adopted.
This rule is connected with Article 141 of Law 4548/2018, which regulates shareholders’ information rights. In practice, the right to information is not a merely procedural formality. It is a tool of corporate oversight. It enables the shareholder to assess the transaction, the financial impact of the resolution, the rationale behind the board’s proposal and, potentially, the existence of conflicts of interest.
However, reliance on lack of information must be specific. It is necessary to examine whether a lawful request was submitted, whether the requested information was connected to the agenda, whether the company’s refusal was justified and whether the failure to provide information materially affected the shareholder’s ability to exercise shareholder rights.
Defective voting, mistake and Article 137 paragraph 5 of Law 4548/2018
Particular interest arises where a shareholder argues that his or her vote was defective due to mistake, fraud or threat. A vote is a declaration of intent, but its impact on the validity of a General Meeting resolution is not assessed in isolation.
Under Article 137 paragraph 5(b) of Law 4548/2018, a General Meeting resolution cannot be annulled because individual votes are null or voidable, unless those votes were decisive for achieving the required majority.
Therefore, even if a vote is independently defective, that alone is not sufficient to overturn the resolution. It must be shown that, without that vote, the required majority would not have been reached. This issue is particularly important in resolutions concerning share capital increases or reductions, changes to the board, approvals of transactions, corporate transformations or decisions that alter the position of specific shareholders.
The four-month preclusive period and the need for immediate action
An action for annulment of a General Meeting resolution is subject to the four-month preclusive period under Article 137 paragraph 8 of Law 4548/2018. The period starts from the date on which the resolution was adopted or, where the resolution is subject to publicity requirements, from its registration with the Greek General Commercial Registry, known as G.E.MI.
This deadline is not a mere procedural detail. It is a substantive limit on judicial protection. If it expires without action, the right to seek annulment may be definitively lost. This is particularly important in practice because, otherwise, the company could remain for a prolonged period in institutional uncertainty as to the validity of a General Meeting resolution. Such uncertainty would be especially problematic in relation to resolutions concerning share capital, board elections, approvals of transactions or corporate transformations.
Greek Supreme Court case law, in particular Supreme Court judgment No. 228/2022, highlights the institutional purpose of this short deadline: legal certainty and the rapid resolution of disputes concerning the validity of General Meeting resolutions. The company, its shareholders and third parties dealing with it cannot remain for an extended period in uncertainty as to whether a critical corporate resolution is valid or capable of being overturned.
For this reason, timely review of the resolution, the minutes, the notice of the meeting, quorum, majority and shareholder information rights is critical. Delay may limit or exclude options that, at an early stage, could have been effective.
Abuse of majority power and minority shareholder protection
Abuse of majority power is one of the most complex grounds for challenging a General Meeting resolution. Under Article 137 paragraph 2(b) of Law 4548/2018, a resolution is voidable if it was adopted through an abuse of majority power, within the meaning of Article 281 of the Greek Civil Code.
It is not enough for the minority simply to disagree with the business decision of the majority. It must be shown that the majority exercised its corporate power in a manner exceeding the limits of good faith, accepted business ethics or the corporate purpose.
Abuse may arise where the majority uses the General Meeting to strengthen its own position disproportionately, weaken the minority, impose changes without adequate corporate justification or approve transactions that raise conflicts of interest.
However, where the resolution also serves a genuine corporate benefit, the analysis becomes more complex. The court must then assess the balance between the benefit to the company and the harm to the minority. Challenging such a resolution therefore requires not only legal argument, but also evidential support regarding the financial and corporate reality of the case.
Related-party transactions and conflicts of interest
General Meeting resolutions concerning related-party transactions require particular attention. These transactions often lie at the heart of corporate disputes, especially where they involve board members, major shareholders or persons exercising material influence over the company.
In such cases, the General Meeting may operate as an approval mechanism, particularly where the board of directors cannot decide due to a conflict of interest. The process, however, must be assessed not only formally, but also substantively. Was there genuine disclosure? Was the transaction in the company’s interest? Was there sufficient transparency? Was the majority used to legitimise a transaction benefiting specific persons?
For minority shareholders, investors and management teams, related-party transactions require enhanced scrutiny. They may become a basis for judicial challenge, but also a field in which the company may need to defend itself against unfounded or strategically motivated challenges.
Interim measures and provisional judicial protection
In certain cases, filing an annulment action may not be sufficient to protect the interests of the shareholder or the company effectively. Where implementation of a General Meeting resolution may create immediate and difficult-to-reverse consequences, interim measures may need to be considered.
Interim relief is particularly important in resolutions concerning changes to share capital, corporate governance, approvals of transactions, distribution of financial benefits, financial statements, dividend distributions, management remuneration, related-party transactions or changes affecting the position of the minority.
Interim relief, however, requires a specific legal basis, a legitimate interest and evidence of risk. The court must be satisfied that there is urgency or a risk of irreparable or hardly reparable harm. Therefore, interim protection should form part of an overall litigation strategy and should not be treated as a standard ancillary step to an annulment action.
Strategic approach to challenging a General Meeting resolution
Challenging a General Meeting resolution is not a mechanical process. It requires immediate diagnosis, selection of the appropriate legal basis, assessment of the available evidence and understanding of the underlying business stakes.
For a minority shareholder, it may operate as a means of protection against abusive resolutions. For the company, it may require a swift defence in order to avoid disruption of its operations. For an investor, a disputed General Meeting resolution may affect due diligence, financing, an acquisition or corporate control.
A proper legal strategy is not limited to the question whether a ground for annulment exists. It includes assessment of timing, procedural tactics, the potential for interim relief, the evidential basis, the relationship with parallel corporate or commercial disputes and the impact of each step on the company.
Conclusion
Defective General Meeting resolutions lie at the core of modern corporate disputes. They do not concern only the formal legality of a meeting. They concern the balance between majority and minority shareholders, the protection of corporate functioning, transactional certainty and, often, the actual control of the company.
In such cases, the value of legal representation lies in the timely identification of the issue, the selection of the appropriate strategy and the ability to connect legal analysis with commercial reality.
In disputes concerning the validity of General Meeting resolutions, speed, precision and a holistic approach may determine not only the outcome of the court proceedings, but also the overall balance within the company.
