Finding the relevant decision

In a database of 412 decisions, finding the one that answers your question takes a good method. The TAO search engine combines free text, filters and operators, and ranks results by relevance.
It works in all three languages: a term entered in French also finds decisions summarised in English or Spanish.
This page presents the method, the filters and tips for refining.

Simple and advanced search
Simple search accepts a few words ("authenticity warranty appraisal") and returns the closest decisions. Advanced search lets you add filters: chamber, theme, article, year, language, presence of an action for annulment.
The operators AND, OR and NOT work as in the BIOP database. Quotation marks search for an exact phrase. You can also search by reference number.



Reading and sorting results
Each result shows the reference, a summary title, the date, the themes and an extract of the summary. Results can be sorted by relevance, by date or by theme. Results indicate the decisions most cited in commentaries.
A button lets you find neighbouring decisions, that is, those sharing the same articles and keywords. This function helps build an overview of the case law on a question.
Alerts and export
Registered users can save a search and receive an alert when a new matching decision is published. Results can be exported as PDF or CSV for inclusion in a note or brief.
Export respects anonymity: it contains only the public data of the entry. It is time-stamped to record the date of consultation.
Beyond the TAO database
The TAO database can be supplemented by other sources: State case law, collections from other arbitration institutions, academic publications. A research guide, available for download, lists the main resources for art law.
Each year the Registry organises a case-law research workshop for students and young lawyers, in collaboration with several universities.
