As a result of liberalization of the telecommunications industry many drastic changes are currently taking place in the Dutch telecommunications market. The fact that new providers are entering the market and the increasing technical possibilities make it almost impossible to keep up with the developments in this sector. Changes as a result of liberalization are also taking place in legislation, although at the time of implementation legislation is often already behind on developments. This article will discuss some important recent developments in Dutch telecommunications law. First of all, the outlines of the Bill for a new Telecommunications Act, based on a completely liberalized market for telecommunications networks and telecommunications services, will be addressed. Subsequently, the auction of the frequencies for mobile telecommunications held in February 1998 will be discussed. Then we shall discuss the developments in the area of (fees for) interconnection and special access, which may have an important influence on the fees for voice telephony. Finally, we shall address the definition of competence of the various supervisors of the telecommunications industry. It must be emphasized that these are only some of the important developments in Dutch telecommunications law, and that this article does not pretend to give a full picture of the recent developments in that area of law.
