C-158/96, Kohll & Decker [1998]

• Context: This case concerns Article 56 TFEU, which addresses the free movement of services, with a particular focus on cross-border healthcare.

• Facts: A Luxembourg citizen, Mr. Kohll, traveled to Belgium to obtain glasses for his daughter, and the cost was covered by his Luxembourg health insurance. Luxembourg refused to reimburse him for the expenses incurred in Belgium.

• Outcome: The European Court of Justice (ECJ) ruled that Luxembourg was obligated to reimburse Mr. Kohll. The Court established the right to cross-border healthcare within the EU, asserting that member states must reimburse costs for healthcare received in another member state under the same conditions as if the care had been provided domestically.
