What must be demonstrated in special cases regarding the free movement of goods?

In the context of the free movement of goods within the European Union and similar economic areas, there are specific allowances for certain restrictions. The correct answer focuses on the fact that while the principle of free movement aims to eliminate barriers to trade, there are legitimate justifications for imposing restrictions, specifically when it comes to safety and environmental concerns.

For instance, member states may implement regulations to protect public health or the environment, including enforcing standards that products must meet to ensure they do not harm individuals or ecological systems. These restrictions must be proportionate and justified but are completely legitimate under EU laws, as they serve an essential role in safeguarding citizens and promoting sustainability.

Products do not necessarily have to be adapted to local needs; the primary aim is to allow goods to circulate freely. While complete freedom might sound ideal, it doesn't take into account the necessary precautions that must sometimes be put in place for public safety and environmental protection. Additionally, the notion that only government-approved goods can be moved is too restrictive and does not accurately reflect the balance sought between regulation and free trade.
