EU Law

There are three sources of law within the EU legal system:

'Primary legislation' – the treaties and agreements of similar status
'Secondary legislation' – laws made under the powers established by the treaties
Case law – the accumulated body of legal decisions built up by the European courts

Together, this body of jurisprudence constitutes the acquis communautaire, with which all member states – and aspirant member states – are required to comply with and to render their domestic laws consistent with, under pain of sanctions.
