Decker v Caisse de maladie des employés privés Case C-120/95, [1998] ECR I-1831
Facts
Nicolas Decker, insured under Luxembourg’s social-security scheme, obtained a prescription for spectacles and purchased them from an optician in Belgium. His insurer refused the ordinary flat-rate reimbursement because he had not obtained prior authorisation for buying the medical product abroad. Decker challenged that condition. The national proceedings raised whether social-security administration was exempt from free-movement rules and whether the authorisation requirement could be justified by financial or health concerns. The Court considered reimbursement at the home scheme’s established rate, rather than an unrestricted claim for any foreign healthcare expense.
Legal Issue
Could a social-security scheme refuse its usual flat-rate reimbursement for spectacles purchased in another Member State solely because prior authorisation had not been obtained?
Held
The Court held that the restriction was incompatible with free movement of goods. Requiring authorisation for foreign purchases encouraged insured persons to buy domestically and therefore impeded imports. Member States retained power to organise social security but had to exercise it consistently with the Treaty. On the circumstances considered, reimbursing the normal fixed amount did not establish a threat to the scheme’s financial balance. Nor did the asserted health concerns justify the restriction given the relevant professional safeguards. The ruling addressed the particular reimbursement rule for spectacles and did not eliminate all authorisation systems for cross-border healthcare, especially where hospital planning or different forms of treatment raise distinct considerations.
⭐ Legal Principle
National social-security rules remain subject to free movement of goods. A prior-authorisation requirement for ordinary reimbursement of medical products bought in another Member State must be justified; the label of social security does not itself exempt it.
Significance
Decker shows how a reimbursement condition can restrict trade without prohibiting importation. It should be distinguished from hospital-treatment cases, where planning and capacity may supply different justifications. The amount and nature of reimbursement matter: the claim concerned the domestic flat rate. Present UK cross-border healthcare entitlements must be established under the relevant legislation and arrangements rather than inferred directly from this membership-era judgment.
Common exam questions about this case
How can reimbursement rules restrict goods without banning imports?
They can make foreign purchases financially less attractive by denying a benefit available for domestic purchases. That incentive can influence where patients buy medical products and impede trade. The Court therefore assessed the practical effect of the condition rather than requiring a formal prohibition at the border.
Why did the flat-rate character of the claim matter?
Decker sought the usual reimbursement amount, not unlimited payment of foreign costs. That limited the claimed financial impact on the home scheme and affected the justification analysis. Different reimbursement structures or treatment arrangements could raise other concerns, so the facts should not be reduced to a universal healthcare rule.
Does Decker abolish prior authorisation for every treatment?
No. It addresses the specific purchase and reimbursement of spectacles. Hospital treatment and other healthcare arrangements can involve planning, capacity and financial considerations requiring separate analysis. A strong answer identifies the product or service, the payment sought and the precise justification rather than treating all healthcare as interchangeable.
