3. Spain has passed the following law: “Whereas the Spanish culture has been strongly diminished since joining the EU, and whereas the Spanish culture is an important part of our country’s heritage and charm. In an effort to maintain our rich culture it is hereby enacted that no computer keyboards shall be sold in Spain unless said keyboard includes the letter “n” with a tilde (~) over it, as this letter is an important part of the Spanish language and will likely disappear if we do not protect it.

To explore the issue of the law passed in Spain and determine the legality of such a measure within the context of EU law, we can consider the following steps:

1. Identify the relevant EU laws: In this case, we need to examine whether the law passed by Spain is in line with the principles and regulations established by the European Union.

2. Use EU primary sources: To understand whether the Spanish law is in compliance with EU regulations, you should refer to primary sources such as the Treaties of the European Union and secondary legislation.

3. Investigate EU language protection: The EU recognizes language diversity and promotes the preservation of linguistic heritage. This can be seen through efforts such as the European Charter for Regional or Minority Languages.

4. Consult EU directives on consumer products: EU law covers the regulation of consumer products, which might contain provisions related to the sale of computer keyboards.

5. Analyze any conflicting regulations: If there are specific EU provisions that conflict with the Spanish law, it would need to be determined whether the Spanish law infringes upon EU rules or if there might be exceptions or justifications.

By conducting research based on the steps mentioned above, you can gain a clearer understanding of the compatibility of the Spanish law with EU regulations. It is important to thoroughly examine the relevant EU laws and seek legal expertise in determining the lawfulness of the Spanish legislation.
