2 Consolidated version of 10 December 1992, OJ 1992 C 325, p. 1.

3 See on this point, amongst others, judgments in Case 38/77 Enka v Inspecteur der invoerrechten en Accijnzen [1977] ECR 2203; Case 296/84 Sinatra v FNROM [1986] ECR 1047; Case 240/87 Deville v Administration des Impôts [1988] ECR 3513; and Case C-227/89 Ronfeldt v Bundesversicherungsanstalt fur Angestellte [1991] ECR I-323.

4 It should, however, be pointed out in that connection that the Court has made it clear that Articles 48(2) and 51 of the Treaty must be interpreted as precluding the loss by a workerof social security advantages as a result of the inapplicability of conventions concluded between two or more Member States and incorporated into their national law: see judgment in Rönfeldt v Bundesversicherungsanstalt für Angestellte, cited above.
