PRACTICE NOTES
In brief
The free movement of goods, the freedom to provide services, the freedom of establishment, and the free movement of capital (collectively, the ‘four freedoms’) operate as constraints imposed by the EU Treaties upon EU Member States to secure the overall functioning of the EU Internal Market. This variety of negative integration has clear limits. Most domestic restrictions falling within the reach of the four freedoms can, however, be justified, provided such restrictions are proportionate. While the Court of Justice has assumed a particularly important and significant role in interpreting the four freedoms (and their limits), any remaining national barriers can ultimately only ever be removed through harmonisation measures enacted by the EU (‘positive’ integration). For further reading on this, see Practice Note: Harmonisation. This Practice Note examines the four freedoms underpinning the EU Internal Market in greater
