Collection of reports of European network of legal experts in gender equality and nondiscrimination on recent national case law and good practices on equal pay. These reports provide both insight into the .developments and the shortcomings of the enforcement of the equal pay principle in practice. First of all there is a lack of public availability of national case law on the equal pay principle between women and men. The lack of pay transparency might play a role in the limited number of legal proceedings on equal pay matters. Besides, the concept of positive action does not always seem to be well understood. In many countries, equality bodies play an active role in the enforcement of equal pay at national level. The reported examples on good practices show how diverse the initiatives at national level are, and illustrate a trend towards more obligatory measures aimed at employers.
