European Case Law Identifier


The European Case Law Identifier is an identifier for court decisions in Europe. The identifier consists of five elements separated by colons: ECLI::::. The standard is laid down in the Council Conclusions inviting the introduction of the European Case Law Identifier and a minimum set of uniform metadata for case law of the European Union. The ECLI framework also contains a set of uniform metadata to improve search facilities for case law. Court decisions that have an ECLI assigned can be indexed by the of the .

History

The concept of ECLI was first launched at the Legal Access Conference and at Jurix Conference on Artificial Intelligence and Law in Florence.
Around the same time, the study by a task group of the EU Council Working Group on e-Law showed that accessibility of judicial decisions, both at the national and European level, was seriously hampered by the lack of standardised identifiers and metadata:
The task group suggested to establish a voluntary common identification system based on the European Case-Law Identifier. ECLI as an identifier would be linked to an index with references. This would enable any citizen or legal practitioner to find any decision to which ECLI has been attributed from any public or private register or database in the EU. In addition a Dublin-core implementation for case-law should be established to facilitate searching case-law in different search engines.

Based on the report of this task group, the Council of Ministers agreed on the principles of ECLI and common metadata, and asked the EU Council Working Party on Legal Data Processing to elaborate the initial work. This continued work resulted in the Council Conclusion inviting the introduction of the European Case Law Identifier and a minimum set of uniform metadata for case law of the European Union, decided upon by the Council of Ministers on 22 December 2010. It was published in the Official Journal of 29 April 2011.

Identifier construction

ECLI does not primarily identify a paper or electronic document containing a judgment, but instead identifies the court decision at a more abstract level. In the terminology of the Functional Requirements for Bibliographic Records on which it is based, ECLI is a work-level identifier. It is constructed with the intention to be meaningful, open, technological neutral, recognisable for both humans and computers, error-proof and interoperable with other identifiers. The formatting rules for ECLI are prescribed in detail in the Annex to the Council Conclusions. Summarized, an ECLI always consists of five parts, separated by a colon:
Only the Latin alphabet is to be used, and that ECLI is case-insensitive, although it is written preferably in capitals.
An example of a case law identifier of the Rotterdam court is ECLI:NL:RBROT:2013:5042, which indicates a Dutch decision of 2013 of the Rotterdam court with serial number 5042.

ECLI website

According to paragraph 4 of the Annex to the Council Conclusions an ECLI website has to be set up, containing
The was set up within the frame work of the e-justice portal of the European Union.

ECLI search engine

According to paragraph 5 of the Annex to the Council Conclusions an ECLI Search Engine has to be set up, enabling search by ECLI and metadata. This launched on 4 May 2016. It provides access to national and European case law, stored in whatever database. Searches are possible on the basis of the ECLI, its metadata as well as full-text.
As prescribed by the Council Conclusions a resolver is available at https://e-justice.europa.eu/ecli/; with an ECLI typed after it, this link with show all available information on this ECLI, from whatever indexed website. As an example: https://e-justice.europa.eu/ecli/ECLI:CZ:NS:2015:32.CDO.2051.2013.1
shows from, a decision from the Czech Supreme Court, the information from the website of that court as well as from the of the Association of Councils of State and Supreme Administrative Jurisdictions of the EU. The latter document also has English and French metadata.
Documents are indexed by the ECLI search engine in cooperation between the European Commission and data providers, using the sitemaps protocol and robots.txt.

Organisation

The Council of Ministers is responsible for any future changes in the standard, while the European Commission is responsible for the ECLI-website and the maintenance of the ECLI Search Engine.

National level

Every Member State must have a national ECLI co-ordinator. The main responsibilities of this national ECLI co-ordinator are:
According to the Council Conclusions, Member States are free to decide on their own implementation route. A big-bang scenario is possible, but also a step-by-step approach is allowed. International organizations may also participate and can request a "country code" from the European Commission.
The table below lists all EU Member States and their current state of ECLI implementation. Also relevant European organisations that have implemented ECLI are included.

Metadata

are to be attached to documents containing a judicial decision. They can relate to the ECLI itself, but also to a specific editorial version. In the Council Conclusions nine mandatory and eight optional metadata are listed. All these are based on the Dublin Core metadata standard. The mandatory means that without these metadata, a document can not be indexed by the ECLI Search Engine.

Mandatory metadata

The mandatory metadata, as listed in the Annex to the Council Conclusions, are:
