Corporate Law · Case Update
In a decision of significant practical import, Portugal’s Supreme Court of Justice (Supremo Tribunal de Justiça) has held that a shareholders’ resolution is voidable under Article 58(1)(b) of the Portuguese Companies Code where a sole director (“administrador único”) exercises voting rights in an abusive and dolus-laden manner to secure an illegitimate dominance over a corporate group — at the expense of a co-shareholder holding an equal 50% stake.
The case arose in the context of a family-owned corporate group comprising two companies: a holding company (SGPS) and its wholly-owned subsidiary. Each branch of the founding family held exactly 50% of the share capital of the parent entity — an equal split that had governed the group’s management for decades on a consensual and cooperative basis.
On 2 January 2020, the sole director of the parent company — without prior notice to the other shareholder, and in circumstances of deliberate urgency — convened a universal general meeting of the subsidiary and proceeded to appoint himself and his daughter to that company’s governing bodies for the 2020–2023 mandate. Critically, this was done on the very same day that a court-ordered appointment of a provisional director was handed down in separate proceedings, with registration completed on 7 January 2020 — the date the judicial decision was notified to the parties.
“The director made use of his position — which he manipulated in a deliberate and dolus manner — to preempt the effects of a judicial decision he knew was imminent, appointing himself and his daughter to the governing bodies of the subsidiary in a clandestine and urgent manner, to the exclusion of the other shareholder.”
The Supreme Court found that the resolution of the subsidiary’s general meeting was voidable on grounds of abuse pursuant to Article 58(1)(b) of the Portuguese Companies Code (Código das Sociedades Comerciais). The Court held that the conduct of the sole director— in his capacity as representative of the parent company, the subsidiary’s sole shareholder — constituted the paradigm case of an abusive vote: the exercise of voting rights with the deliberate purpose of obtaining a special advantage for himself and for a related party (his daughter), to the clear detriment of the other shareholder.
Of particular doctrinal and practical relevance, the Court’s reasoning placed considerable weight on the foundational principles governing the operation of this family corporate group. The judges noted that the 50/50 ownership structure was not merely a numerical coincidence but reflected a governing compact of mutual consent, strategic co-management and shared control — one maintained consistently since the group’s founding. The unilateral rupture of that compact through covert and rushed deliberative action was held to be irreconcilable with the duty of loyalty enshrined in Article 64 of the Companies Code and with the ethical standards underpinning corporate governance in closely-held family companies.
Why this ruling matters
In family companies structured on equal footing — where each branch holds precisely 50% of the voting capital — the risk of one party exploiting its management position to consolidate unilateral control is not hypothetical: it is structural. Portuguese law offers no statutory veto right in such configurations, and the general meeting of a 50/50 company is prone to deadlock. This ruling confirms that Article 58(1)(b) of the Companies Code operates as a meaningful check on that risk: where a shareholder exercises voting rights not in pursuit of the common corporate interest but to obtain a personal advantage and to entrench a position of illegitimate supremacy, the resulting resolution is susceptible to annulment — regardless of whether the vote was formally regular. The decision also reinforces that the concept of “indirect shareholder” may be invoked to grant standing to a shareholder of the parent company to challenge resolutions passed at the level of a wholly-owned subsidiary, where the two entities are functionally and economically inseparable.
The Supreme Court accordingly granted the appeal (revista procedente), annulled the challenged resolution of the subsidiary’s general meeting and ordered the cancellation of the corresponding commercial registry entries. The decision was reached by unanimous vote.
This is a significant victory for our client, who had consistently maintained that the January 2020 resolutions were the product of bad faith, deliberate concealment and an abuse of corporate power wholly at odds with the governance framework that had defined this group for more than four decades.
