Database to ECJ jurisdiction on tax law

 

In cooperation with the Centre for European Economic Research in Mannheim, a database to the jurisdiction of the ECJ on tax law from 1960 to this day is being developed.

The aim of the project is to systemise the enacted decisions and to gain access to the relevant information in a clearly arranged way.

Thereby, the database enables a variety of usages: It is not only possible to get a quick overview about the particular decision, but also to compare the decisions on the base of different angles. Via keyword searching decisions which are relevant for the present case or research can be found easily. Furthermore, it is possible to prepare statistics to diverging questions. For instance, it can be responded to the question how often the justification “coherence of the fiscal system” has been adduced and how often it has been seen as given.

Fundament of the database are, beside of a list of jurisdiction with fiscal reference, which has been published by the European Commission, the decisions themselves which can be found in the CURIA-database of the ECJ, as well as contributions in magazines and monographs with reference to the particular decision.

On this base all decisions get analysed and systematically recorded. After the completion of a testing phase with decisions of different periods, the implementation of new decisions is carried out chronologically.

The database contains the following information to every decision:

In technical respect, the database should in the long term get a user-optimised interface and an even more effective search function, so that the database can be made accessible to general public for free. Furthermore, there should be carried out a translation of the database into other languages, especially into German.
