What would count as an explanation of a legal concept’s authority? Showing that lawyers keep using it is one answer. Showing why particular interpretations become difficult to ignore is a more demanding one.
In a peer-reviewed conceptual article published on 21 September 2026, Oguz Kaan Pehlivan distinguishes three questions: what makes communication legal; how particular meanings become established; and how concepts remain recognisable through historical change. His “graduated closure” connects systems theory with scholarship on interpretation. International law’s recurring argumentative forms need not produce agreement about their content. Selected doctrinal cases illustrate the proposal; they are not a systematic empirical test.
The article’s useful discipline is to resist treating recurrence as a complete explanation. Its discussion of investment arbitration and changing due-diligence standards directs attention towards interpretive communities, unequal authority and repeated application. The treatment of temporal closure is especially careful: time is a different analytical axis, not simply a third compartment beside operations and meanings. These distinctions make the proposal more precise than a general assertion that law is socially situated.
My reservation concerns the boundary between explaining authority and naming its accumulation. A study could discover that influential interpretations come from influential institutions without explaining much. It would need measures that do not define authority by the very uptake being explained. Researchers might distinguish an institution’s prior standing, its resources and access to audiences, the reasons offered in a particular interpretation, and later patterns of acceptance. Otherwise a persuasive conceptual distinction risks becoming a circular empirical story.
A second difficulty is causal direction. Does concentrated interpretation stabilise meaning, or do already converging expectations make a particular institution a convenient reference point? Both could happen. A useful comparison would examine similarly placed interpretations that travelled differently, including unsuccessful ones. Tracking only enduring formulations would make institutional memory look more orderly than the process that produced it. This is a proposal for extending the inquiry, not a claim that the article has performed that comparison.
There is also a reasonable alternative reading: the contribution may be a productive division of explanatory labour rather than a refutation of systems theory. An account of a practice’s boundary need not itself explain every distribution of influence inside it. The stronger criticism would show that its commitments prevent the missing explanation, not merely that additional institutional analysis is required. That distinction matters for assessing both the paper’s originality and the reach of its challenge.
My Autopoietic Ecology reading starts with the work that makes an interpretation usable again. The public Concept Guide separates an activity’s continuation from the renewal of its enabling capacities. Applied to this problem, that suggests following translation, record-keeping, teaching and opportunities to challenge a formulation—not assuming that citation alone demonstrates a self-sustaining practice.
This is not an equation between graduated closure and AE’s rough closure. The latter asks how a definite operation remains dependent on conditions it does not contain or control. The practical question here is whether those who maintain the circulation of legal knowledge also have the standing to revise it. That question connects with the Research Programme’s inquiry into meaning, institutions and recognition; it is my extension, not the author’s finding.
The extension must earn its place. If differences in maintenance resources and access to challenge add little explanatory value once formal powers and the quality of reasons are considered, the AE account should be narrowed. If they help explain why otherwise comparable interpretations gain or lose practical force, they identify something worth investigating. A useful theory should make that disagreement easier to resolve, not merely supply a richer vocabulary for the same observations.

Author’s response — Oğuz Kaan Pehlivan

Thank you for reading the article so closely and for writing the review. I found no factual errors in your summary, and I am grateful in particular for your reading of temporal closure as a different axis rather than a third compartment, which is exactly the distinction I hoped to draw. You are welcome to publish this response alongside the review.
Your three questions point to where the article’s work ends and further work must begin, and I would like to acknowledge that openly. A single article can propose a framework and illustrate it through selected cases; it cannot also carry out the empirical programme that such a framework calls for. The article says as much in presenting its indicia as a research agenda, and your review helps to specify that agenda more precisely.
On circularity; I accept that semantic authority, understood as accumulated uptake, cannot by itself explain the uptake it names. The article begins to address this by resting its predictions on structural variables, such as the concentration of interpretive sites and their tempo, rather than on uptake alone. But developing measures that fully separate prior standing, resources, the quality of reasons and later acceptance is a research project in its own right, and your distinctions offer a useful starting point for it.
On causal direction; I think both directions are likely to operate, and the article does not resolve which predominates where. Your proposal to compare similarly placed interpretations that travelled differently, including unsuccessful ones, is exactly the kind of study needed. Readings that did not become dominant, such as the expansive construction of fair and equitable treatment in Tecmed, would be a natural place to begin.
On extension versus refutation; your alternative reading is close to my own position. The article does not seek to refute systems theory as such, but questions the claim that it is sufficient to explain the stabilisation of legal meaning. Whether graduated closure is best understood as an extension of the theory or as a challenge to some of its commitments is a question I expect to become clearer as the work develops.
The maintenance work you highlight, including translation, record-keeping and teaching, also deserves more systematic attention than the article could give it. These are questions I intend to pursue in further work, and I expect the framework to mature through exactly this kind of engagement.
Thank you again for the careful reading.
