Being accountable

An arbitral tribunal is a private institution, but its legitimacy depends on its transparency. Each year the TAO publishes a full report on its activity and thematic studies, and keeps the archives of its publications since its creation in 2011.
All these documents are free and accessible online, in French, English and Spanish. They serve practitioners, researchers and journalists.
This section presents the annual report, the studies and the archives.
Tribunal reports in figures
Source: Registry of the OIMAP Arbitral Tribunal.
Three series



Why publish
Transparency allows users to understand how the tribunal works, to assess its performance and to anticipate its developments. It also encourages continuous improvement: time limits, costs and parties' satisfaction are measured and commented on.
It meets a requirement of good governance: arbitration institutions increasingly publish their statistics, methods and decisions, while respecting the confidentiality of cases.
What the reports contain
The annual report presents the year's activity: number of cases, durations, costs, mediations, enforcement, composition of the tribunal, evolution of the Rules, accounts. Thematic studies go deeper into a subject: time limits, authenticity, restitution, arbitration and technology, parity.
Method notes explain how the statistics are produced. Compendia of decisions bring together landmark awards accompanied by commentaries.
Access and reuse
All the reports are freely accessible and reusable with acknowledgement of the source. Figures are published as CSV to allow independent analysis. A free subscription gives notice of new publications.
The Registry answers requests from journalists and researchers, respecting confidentiality. Presentations are held each year on publication of the report.
Dialogue with users
Each year the tribunal holds a meeting with its users to present its report, gather their observations and discuss possible developments. Proposals are examined by the quality committee.
A satisfaction survey, conducted among the parties at the close of each case, feeds into the report. Its results are published: 92% of parties say they are satisfied or very satisfied with the procedure.
