Ex officio meaning

What does Ex officio mean?
In legal practice, describes a power, duty, title or membership held by virtue of holding a particular office, not by separate appointment or election. An ex officio member of a board, committee, court or statutory body sits automatically because they occupy another role; when they leave that office, the ex officio status ends. The term commonly appears in legislation, constitutions, rules of court and corporate or charity governing documents across England & Wales, Scotland, Northern Ireland and Ireland. It is generally a descriptive Latin expression rather than a defined legal term, though specific statutes and instruments may prescribe its effect in context. Whether an ex officio member has voting rights, counts towards quorum, or bears fiduciary or other liabilities depends on the relevant statute or governing instrument; “ex officio” alone does not determine such rights. Acting ex officio means acting in one’s official capacity, rather than personally. Usage is broadly consistent across the UK and Ireland.

Germany: BGH confirms minimal reasons suffice for missing arbitrator's signature; courts must verify arbitral award formalities ex officio (ZPO ss 1054, 1059)

What are the practical implications of this case? The BGH’s ruling carries notable consequences for the validity of arbitral awards regarding formalities such as signatures. It emphasised that courts must, of their own motion, confirm compliance with all procedural conditions in Section 1059 of ZPO, even where the parties do not raise them. This includes verifying that the arbitrators have signed the award, or that there is a legitimate explanation for any missing signature. A refusal to sign, or a determination that obtaining a signature should be avoided, constitutes a proper reason under Section 1054 (1) sentence 2 of ZPO. An instrument that fails to satisfy these formalities is not an award within the meaning of Section 1059 of ZPO at all, and therefore cannot be the subject of an application to set aside. Consequently, German courts should not demand elaborate justifications when the formal criteria appear fulfilled. By way of example, a brief note on the award stating that a signature could not be obtained is sufficient for...

UK and EU cartel enforcement: expanding theories, ex officio detection, labour market and algorithmic collusion, obstruction penalties, and intensified cross-border co-operation—practical takeaways for competition practitioners

The statement cautioned that algorithms may enable rivals to exchange competitively sensitive information, fix prices, or co-ordinate on other terms or commercial strategies in breach of competition laws. It has become evident that both the Commission and the CMA are prioritising ex officio cartel enforcement, including by boosting resources and developing new detection and enforcement tools to drive prosecutions for cartel conduct. This article sets out a review of where these jurisdictions’ approaches to cartel enforcement converge and where they differ. In terms of similarities Broaden the definition of what amounts to cartel behaviour Rely less on leniency applications to trigger cartel probes Enhance detection methods Place greater weight on prosecuting obstruction of justice Strengthen communication and co-operation between enforcement bodies Within the EU, the Commission acts as the principal enforcer for cartel offences that span across Member State borders. At the same time, individual Member States retain their own autonomous powers to apply and enforce cartel rules within...

International trade law weekly: EU BEV countervailing duties, WTO monitoring and services agenda, ICC/UNECE digital standards, UNCITRAL SPEDR, and HMRC customs updates—11 July 2024

In this issue: Subsidies and countervailing measures Anti-dumping WTO Trade in services Dispute settlement Customs Daily and weekly news alerts New and updated content Subsidies and countervailing measures European Commission imposes provisional countervailing duties on BEV imports from China The European Commission has introduced provisional countervailing duties on imports of battery electric vehicles (BEVs) from China, nine months after commencing an ex officio anti-subsidy investigation. The Commission determined that China’s BEV value chain benefits from unfair subsidisation, posing a threat of economic injury to EU BEV manufacturers. The inquiry also assessed the expected effects and implications of these measures on importers, users and consumers of BEVs within the EU. The Commission indicated that any negotiated resolution to the investigation must effectively address the harmful forms of subsidisation identified. See LNB News 08/07/2024 9...

Dutch state immunity in arbitration: jurisdiction and enforcement, waiver, commercial-use exception, asset attachment, burden of proof, bailiff notification, and UN Convention‑influenced Supreme Court case law

State immunity in the Netherlands—introduction This Practice Note examines how state immunity operates in relation to arbitration proceedings in the Netherlands. For a wider primer on state immunity and arbitration, see Practice Note: State immunity and arbitration—general considerations. For Practice Notes covering state immunity across multiple jurisdictions (including England and Wales), consult our subtopic: State immunity and arbitration—overview. State immunity and arbitration—overview States and state-owned enterprises frequently participate in international commercial dealings. Contracts concluded by states—particularly those with overseas private parties—commonly include arbitration agreements. As a result, states are regular participants in international arbitration. Under Dutch law, two categories of state immunity are recognised: State immunity from jurisdiction (jurisdictional immunity) State immunity from enforcement Jurisdictional immunity is a rule that bars a court or tribunal from exercising authority over claims against the state that enjoys the immunity. Enforcement immunity prevents a court or tribunal from enforcing an award or judgment against assets belonging to that protected state. In the...

EU merger control and FSR: jurisdictional thresholds, control test, full‑function JVs, referrals, procedure, standstill and penalties (2023–2026 developments)

NOTE—to see whether notification thresholds in the EU and throughout the world are met, see further: Where to Notify. 1. Have there been any recent developments regarding and are any updates/developments expected in the coming year? Are there any other ‘hot’ issues? As of 12 January 2023, Regulation 2022/2560 on Foreign Subsidies (FSR) came into force. With this instrument, the Commission aims to tackle potential distortions to competition within the EU arising from significant financial support granted by non-Member States.

For mergers, from 12 October 2023, the FSR requires a separate, standalone filing—on top of any required merger control notification—for deals meeting the following criteria: (i) the target, joint venture, or at least one merging party is established in the EU and achieves an aggregate EU turnover of no less than €500m; and (ii) all...
