EU Commission took actions against Spain

By 1 July 2005 Member States should have had taken measures to put into practice the PSI Directive. Spain, among other 4 countries Portugal, Luxemburg, Austria and Belgium, did not do so and was taken to the European Court of Justice by the EU Commission. By doing this, the Commission aimed to achieve full implementation of the re-use norms across the EU landscape.
The EU is determained to make good use of the PSI due to the enormous economic potential. Back in 2005 it was estimated that the raw material for new added value services and products was worth from €10-48 billion in the EU.
