Scholarship informs practice

A decision on its own says little. A commentary places it within the whole body of case law, draws out the principles, points out the limits and suggests avenues. The TAO invites academics and practitioners to comment on its most important decisions.
The collection holds 38 commentaries, published in French, English or Spanish. They are accessible free of charge from the decision's entry and grouped by theme.
This page presents the authors, the method and the most studied themes.

Who comments
The commentators are law professors, lawyers, art historians, curators and former arbitrators. An editorial committee independent of the tribunal chooses the authors and ensures a diversity of viewpoints. Arbitrators who sat in the case may not comment on the decision.
Each commentary is peer-reviewed by two reviewers before publication. Authors declare any links with the parties, their counsel or the art market.



Method of a commentary
A commentary follows a constant structure: presentation of the facts, analysis of the question of law, discussion of the outcome, placing in perspective with other decisions and with comparative law, and finally practical significance. It avoids going back over the merits of the case, which are covered by confidentiality.
The length is ten to twenty pages. A ten-line summary opens each commentary to allow a quick read. The bibliography lists useful references.
Using the commentaries
For counsel, a commentary helps anticipate the tribunal's reaction to an argument. For an arbitrator, it provides a critical view of the case law. For a student, it serves as an example of legal reasoning applied to art.
Commentaries may be cited in submissions, like any scholarly publication. Arbitrators are not bound by them, but they read them: scholarship influences practice.
Seminars and training
Each year the TAO organises two case-law seminars bringing together arbitrators, lawyers and academics. The most important commentaries are discussed there, and the proceedings are published. Workshops for students offer practice in analysing anonymised decisions.
These exchanges feed the thinking of the committee drafting the Rules, which finds concrete suggestions for amendment there.
