This report analyzes the compatibility of proposed legislation by the Spanish government with the laws of the European Union, focusing on the free movement of goods. The report examines four key areas: a proposed ban on e-cigarettes containing propylene glycol, a ban on TV advertisements for chocolate liquor products, mandatory inspections for imported microwave ovens, and a ban on importing motor vehicles over 15 years old. It references relevant articles of the Treaty on the Functioning of the European Union (TFEU) and other EU directives, such as the Tobacco Products Directive (TPD). The analysis concludes that while some proposals align with EU directives, others, particularly those involving outright bans, may contravene EU law by restricting trade and the free movement of goods. The report highlights the balance between national regulatory autonomy and the overarching principles of the European Union and concludes that Spain must comply with EU law.
