From a legal perspective the principle of the free movement of goods has been a key element in creating and developing the internal market. It is one of the economic freedoms established by the EC Treaty. Articles 28–30 of the EC Treaty defi ned the scope and content of the principle by prohibiting unjustifi ed restrictions on intra-EU trade. Nowadays the internal market goes beyond these three Treaty articles.
Harmonised legislation in many areas has specifi ed the meaning of the internal market and has thereby framed the principle of the free movement of goods in concrete terms for specifi c products. Nevertheless, the fundamental function of the Treaty principle as a key anchor and safety net for the internal market remains unaltered.
2. The Treaty provisions
The main Treaty provisions governing the free movement of goods are: • Article 34 TFEU, which relates to intra-EU imports and prohibits ‘quantitative restrictions and all measures having equivalent eff ect’ between Member States; • Article 35 TFEU, which relates to exports from one Member State to another and similarly prohibits ‘quantitative restrictions and all measures having equivalent eff ect’; and • Article 36 TFEU, which provides for derogations to the internal market freedoms of Articles 34 and 35 TFEU that are justifi ed on certain specifi c grounds. The Treaty chapter on the prohibition of quantitative restrictions between Member States contains, also in Article 37 TFEU, rules on the adjustment of state monopolies of a commercial character.
