“Cassis des Dijon” decision
“Keck” decision
The issue is: does the prohibition only concern the modality of the sale? Is it a selling arrangement? If the provision applies to all affected traders operating in the national territory and affects the marketing of domestic products equally as those from other member-states, the provision is legal. If the prohibition concerns the product itself, the standard is very exacting.
d. Freedom of Capital Transfers,

Gas stations are usually open in France 24 hours per day. Under a French law, gas stations are allowed to sell the same products as supermarkets, which are only permitted to be open from 8:00 a.m. through 6:00 p.m., during those same hours. During hours that supermarkets are closed (as well as on Sundays, when supermarkets are closed), the gas stations (although they are open) are only permitted to sell goods urgently needed by travelers (e.g. sandwiches, drinks) but not goods otherwise sold in supermarkets (e.g. washing powder, cooking oil etc.).
A suit is brought challenging the French law. It is argued that this French law violates the “Freedom of Movement of Goods” of the European Union. If the French gas stations were allowed to sell all products at all hours, they would be able to sell more German goods, Austrian goods etc. What was decision of the European Court of Justice and why?
