OBS_VALUE: See also: Article 6(2) of Directive 96/67/EC, of 15 October 1996 on access to the ground handling market at Community airports, establishes that Member States may limit the number of suppliers authorized to provide certain categories of ground handling in airports. With respect to airports, the law allows the airport operator to restrict the number of service suppliers to no fewer than two. In this case, the airport operator must inform the Ministry of Transport of this restriction. No limitations exist with respect to other modes of transport.
