From 6-8 October, 2025, the Worldwide Courtroom of Justice held public hearings in response to the Worldwide Labour Group (ILO)’s request for an advisory opinion on the next query:
Is the suitable to strike of staff and their organizations protected beneath the Freedom of Affiliation and Safety of the Proper to Organise Conference, 1948 (No. 87)?
The ILO’s query is deceptively advanced. Its reply may have an effect on the modern relevance of the Worldwide Labour Group, the connection between its non-binding ideas and binding conventions, and the quite a few governments and firms which have sure themselves to these devices as ILO members and of their company due diligence initiatives and commerce and funding agreements.
The written and oral pleadings submitted earlier than the ICJ span a number of points, together with whether or not the ILO’s devices represent lex specialis beneath Article 5 of the Vienna Conference on the Regulation of Treaties, which excepts worldwide group treaties from conventional guidelines of interpretation, and whether or not state observe strictly throughout the context of Conference No. 87 helps an interpretation that the Conference protects the suitable to strike. These points are essential and can undoubtedly floor in future weblog posts.
This publish focuses on a associated however distinct argument debated between the ILO’s employee and employer members on the ICJ: whether or not the evolution of a non-binding ILO “precept” of freedom of affiliation to include the suitable to strike embeds that proper into its attendant, binding Conference No. 87, regardless of the Conference’s silence on the matter. As a former ILO lawyer and former U.S. commerce official, this concern strikes me as essential for 2 causes. First, it impacts how references to the ILO’s ideas and rights are interpreted outdoors the ILO, comparable to in commerce agreements. Second, it dangers weakening the ILO’s procedures for adopting binding conventions. If the ICJ advises that non-binding ideas can robotically form the interpretation of binding ILO conventions, then the ILO’s constitutional requirement — that governments, employers, and staff attain consensus earlier than adopting binding obligations — shall be undermined.
To contextualize the request for an Advisory Opinion, this publish first provides an in depth background, specifically (I) the ILO’s tripartite governance design and devices, which ensures that every one ILO conventions are merchandise of a consensus amongst private and non-private actors, and (II) how the ILO’s tripartite consensus broke down over the objections of employers to the ILO supervisory our bodies’ interpretive mandate. I then flip to (III) that argument that the suitable to strike, which has come to be understood within the worldwide group as a vital corollary to the ILO’s basic precept of freedom of affiliation, needs to be interpreted as included (albeit silently) within the scope of actions protected beneath Conference No. 87.
The ILO’s Tripartite Governance Design and Devices
The ILO’s request regards an interpretation of Conference No. 87, which gives that “[w]orkers and employers, with out distinction in anyway, shall have the suitable to ascertain and, topic solely to the foundations of the organisation involved, to hitch organisations of their very own selecting with out earlier authorisation” (Article 2). The time period “organisation” means “any organisation of staff or of employers for furthering and defending the pursuits of staff or of employers” (Article 10). Key to the query earlier than the ICJ, the Conference gives that these organizations “shall have the suitable to attract up their constitutions and guidelines, to elect their representatives in full freedom, to organise their administration and actions and to formulate their programmes”, and that “[t]he public authorities shall chorus from any interference which might limit this proper or impede the lawful train thereof” (Article 3).
The Conference’s textual content doesn’t expressly embody an affirmative proper to strike. Certainly, in accordance with the ILO, in addition to the contributors who spoke on the ICJ on behalf of governments, employers, and staff, the Group’s tripartite members couldn’t attain an settlement on the matter throughout Conference No. 87’s drafting and excluded it from the Conference’s textual content (ILO written submission, para. 307).
That lack of settlement is pretty widespread on the ILO, a singular U.N. group comprised of private and non-private actors. The ILO’s Structure establishes that governments, together with representatives of staff’ and employers’ organizations, share duty and management in adopting, sustaining, and supervising the ILO’s devices. The ILO’s governance is split into three constitutional organs: the Governing Physique, the Worldwide Labour Convention (ILC), and the Workplace.
The ILO’s tripartite members negotiate and undertake binding conventions on the ILC. Due to the constitutional significance of that tripartite session course of, governments could solely ratify an ILO conference wholesale, with out reservations.
The ILO supervises the applying of ratified conventions in legislation and in observe by way of a two-step equipment. Step one is performed by the Committee of Specialists on the Software of Conventions and Suggestions (CEACR), a technical committee composed of 20 specialists appointed by the Governing Physique. The CEACR’s annual report is transmitted to the ILC to tell the latter’s discussions, prompting the second step of its common supervisory course of. Throughout this second step, a standing committee of the ILC, the Convention Committee on the Software of Requirements (CAS), considers, amongst different issues, particular person instances regarding measures taken by member States to present impact to ratified conventions. The CAS is tripartite and makes its supervisory selections by consensus. The listing of instances is decided based mostly on the CEACR’s observations, and the governments are chosen based mostly on negotiations between the CAS’s employer and employee representatives.
Along with binding conventions and non-binding suggestions, the ILO’s devices additionally embody non-binding declarations. The ILO’s 1998 Declaration on Basic Rules and Rights at Work (“1998 Declaration”), an instrument included by reference in quite a few commerce and funding agreements, declares:
that every one Members, even when they haven’t ratified the Conventions in query, have an obligation, arising from the actual fact of membership within the Group, to respect, to advertise and to comprehend, in good religion and in accordance with the Structure, the ideas regarding the basic rights that are the topic of these Conventions….
One such precept is freedom of affiliation, which is the topic of Conference No. 87.
Neither the CEACR nor the CAS supervise compliance with the 1998 Declaration’s basic labour ideas. Nor are governments in any other case publicly assessed for the applying of these ideas in legislation or in observe. The one exception issues the ideas of freedom of affiliation and collective bargaining. The ILO’s Committee on Freedom of Affiliation (CFA) examines complaints alleging infringements of these basic ideas no matter whether or not the alleged offending authorities ratified the attendant conventions, together with Conference No. 87.
The ILO’s Tripartite Breakdown
Though Conference No. 87 doesn’t expressly affirm the suitable to strike, the CEACR has persistently examined the applying of the Conference with the understanding that “the suitable to strike is an intrinsic corollary of the suitable to arrange that’s protected by the Conference.” In line with the ILO’s written submission (Doc. No. 165), the CEACR has persistently held this view since no less than 1985. The CEACR has additionally discovered that “enough safeguards and immunities from civil legal responsibility are vital to make sure respect for this basic proper [to strike]….” (see the ILO’s written assertion, at para. 324).
Through the ILC in June of 2012, the ILO’s Employer’s group objected to the CEACR’s characterization of the suitable to strike throughout the ILO’s Conference No. 87. Citing that objection, the Employer’s group refused to conform to undertake the listing of instances for the CAS. It thus successfully shut down the ILO’s supervisory functioning that yr.
The Proper to Strike in Conference No. 87?
I now flip to the arguments regarding the relationship between the basic precept relating to freedom of affiliation and the Conference that offers it expression. As a preliminary procedural remark, when it submitted its request for an advisory opinion, the ILO requested the Courtroom to permit for the participation of the employers’ and staff’ organizations that take pleasure in common consultative standing with the ILO. These organizations have been: the Worldwide Organisation of Employers (IOE) and the Worldwide Commerce Union Confederation (ITUC), amongst others. The ICJ’s oral proceedings included these non-public actors who spoke alongside governments.
Whereas (or maybe as a result of) the ILO’s intervention in the course of the oral proceedings was primarily restricted to describing its tripartite procedures, the duty of persuading the Courtroom that Conference No. 87 needs to be interpreted to incorporate the suitable to strike fell primarily to the ITUC and people states that spoke in favor of such an interpretation.
ITUC’s key arguments presumed a common settlement amongst states, staff, and employers that the suitable to strike exists as “a part of the basic ideas and rights at work within the ILO,” particularly freedom of affiliation, as set out within the ILO’s Structure (see Verbatim Document 2025/16, p. 34). Accordingly, ITUC urged the Courtroom to think about the suitable to strike as an “inherent and central a part of the suitable of staff and their commerce unions to arrange beneath Conference No. 87.” (ibid).
The ITUC’s argument {that a} function (albeit a silent one) vital to attain a basic precept is contained in its corresponding Conference aligns with the ILO’s Authorized Advisor’s rationalization that the Group’s conventions “give expression” to the related ideas (ibid. at p. 27). Underneath this view, a conference can’t give expression to a precept if it doesn’t, at a minimal, include the precept’s vital options.
Even when we have been to agree that the ILO’s non-binding ideas are inexorably linked to its binding authorized rights, will we essentially agree {that a} proper learn into the previous is robotically, albeit silently, transmitted into the latter?
That step within the authorized evaluation is problematic in view of the drafting historical past and the ILO’s tripartite governance construction. Recall that: (1) the tripartite members agreed that Conference No. 87 wouldn’t embody the suitable to strike on the time of its adoption (ILO written submission, para. 307); (2) no binding obligations could also be adopted absent a two-thirds consensus among the many ILO’s tripartite members; and (3) governments could solely ratify the ILO’s conventions wholesale, with out reservation.
In mild of these safeguards, it could appear the ILO’s conventions needs to be tougher to penetrate than a silent acquiescence throughout the context of its soft-law ideas. Though the CEACR has a longstanding mandate to “decide the authorized scope, content material and which means of the provisions of the Conventions” when executing its supervisory operate, its capability to interpret a Conference in order to introduce a brand new obligation – with out extra – dangers undermining the position of the tripartite members in negotiating the contours of the ILO’s binding devices.
An ITUC consultant’s oral intervention earlier than the Courtroom appears to dismiss the notion that the CEACR is introducing a brand new obligation as “profoundly illogical.” Certainly, he argues, it’s unattainable to acknowledge that the suitable to strike is a corollary of freedom of affiliation within the context of the ILO’s Structure or 1998 Declaration, however not in Conference No. 87. He provides a fairly complicated illustration (translated from French). “If we settle for that being moist is a corollary of immersion in water, you can be moist in any case, whether or not you go swimming within the sea at Scheveningen or get into your bathtub” – the context issues little (see Verbatim Document 2025/16, p. 40).
The Employer’s group disagrees. The ILO’s failure to undertake an instrument that expressly covers the suitable to strike, it argues, displays the constant opposition and political sensitivities among the many tripartite members (ibid. at p. 58). Thus, even assuming arguendo that the ILO’s Constitutional and 1998 Declaration’s precept of freedom of affiliation accommodates a corollary proper to strike, any binding obligation which can emerge in Conference No. 87 should comply with tripartite consensus.
This concern ought to by no means have been raised earlier than the ICJ. Because the proof sufficiently reveals, governments have persistently interpreted their obligations beneath Conference No. 87 to incorporate the suitable to strike. The Employer’s group accepted that the suitable to strike fell inside Conference No. 87 as late as 2010 (see Verbatim Document 2025/16, p. 35). This case ought to have centered solely on whether or not the ILO’s members sufficiently accepted that Conference No. 87 had advanced since its adoption. Neither the employees nor the employers ought to have based mostly their arguments on the evolution of the non-binding precept of freedom of affiliation. Having launched it, nonetheless, these events have introduced the connection between the ILO’s ideas and rights to the fore.
If we dismiss the Employer’s group’s argument and settle for that the ILO’s non-binding ideas could change the interpretation of its binding conventions, then the tripartite technique of negotiating conventions comes into query. Who decides whether or not ideas have advanced? Do these selections outweigh the consensus reached on the ILO’s platform? If there isn’t a significant distinction between the substance of ideas and conventions, and if all governments are sure to the ILO’s basic ideas by advantage of their ILO membership, because the 1998 Declaration stipulates, then why have a ratification course of in any respect?
If the Courtroom decides on this floor and finds that the ILO’s conventions can evolve over the objections of its tripartite members, it dangers undermining the Group’s distinctive governance construction and Constitutional processes.
Somewhat resolve on these grounds, the Courtroom may contemplate a narrower strategy, not superior by the ILO, staff, or employers: by subjecting the ideas of freedom of affiliation to its supervisory physique (the CFA), the ILO’s tripartite members have at all times handled it as sui generis; a precept that exists someplace between the ILO’s non-binding ideas and its binding conventions. This therapy arguably grants the Group some flexibility to take an evolutive strategy to the precise conventions related to freedom of affiliation with out having to deal with the distinctions between its ideas and rights extra broadly – an existential space that may await additional readability.
The Courtroom could, in fact, keep away from the difficulty altogether and attain its conclusion on different grounds. Software of the Vienna Conference and a survey of previous practices throughout the context of Conference No. 87 provide easy pathways to answering the ILO’s query within the affirmative (the probably end result of this case). On the grounds of the evaluation addressed on this publish, nonetheless, the result’s far much less clear.
