Delays in transposing EU law prevent citizens and businesses from enjoying the laws' benefits, create uncertainty as to what rules apply and negatively affect the functioning of the EU's internal market.
Each directive contains a deadline for transposition. By that date EU countries must send the Commission the text of the national implementing measures, which incorporate the provisions of the directive into their legislation.
The Commission checks whether they are complete and meet the objectives set by the directive.
If this is not the case the Commission opens an infringement procedure for 'non communication'. The Commission may also initiate an infringement procedure in the case of incorrect transposition of directives.
Reporting on performance
The Commission publishes an annual report reviewing EU countries' performance on key aspects of the application of EU law and highlighting the year's main developments. The report is also sent to the European Parliament and to national authorities.
