The Competition Tribunal dismissed a lawsuit by WSP Servicios Postales S.A. against the Health Superintendence, as the Superintendence did not infringe the free competition when it assigned Empresa Correos de Chile, exclusively, the dispatch of the certified mail that Isapres are legally bound to send to their affiliates. The foregoing, since the monopoly granted by the D.F.L. No. 171 of 1960 to Empresa Correos de Chile (legal successor of the Mail and Telegraph Service) regarding certified correspondence is currently in force.
