Glossary of summaries
Strictly speaking, EU law consists of the founding Treaties (primary legislation) and the provisions of instruments enacted by the European institutions by virtue of them (secondary legislation - regulations, directives, etc.).
In a broader sense, EU law encompasses all the rules of the EU legal order, including general principles of law, the case law of the Court of Justice of the EU, law flowing from the EU's external relations and supplementary law contained in conventions and similar agreements concluded between the EU countries to give effect to Treaty provisions.
