In overviewing the (scant) empirical evidence gathered on and the literature written about New Social Movements (NSM's) in Belgium this article tries to buttress three general propositions. First, the NSM' highlight a general tendency among social movements today of a thoroughgoing dissociation of the mobilizational potential on the one hand and organizational (decision making) power on the other hand. Second, the NSM's in Belgium have helped substantially in raising participation levels, broadening the action repertoire of the citizens and changing the nature ofparticipation. Third, although participation levels in Belgium are still beneath the West-European averages, the NSM's consitute in Belgium - with the New Right as their direct opponent - a new cleavage line in an altogether weakening system of cleavages.

The generally accepted idea of the "decline ofparties" leads to an obvious assumption on the evolution of party activism: it must be declining. There is however only little empirical research on this topic. We conduct a survey among party members in Belgium, in order to test the decline hypothesis. Four dimensions of membership wilt be measured: the numbers, the intensity of participation, the kind of participation (motivation and incentives) and the turnover.

Under EC law, directives are often used to harmonize legislation of the member states. White directives are binding as to the result to be achieved, they leave the "choice ofform and methods" to the member states. These must then transpose or implement the directives in their national legal order within a fixed period of time. According to 1992 data of the Commission of the European Communities, Belgium occupied a seventh place in the transposition ofdirectives in general (93.6% of the total number of directives transposed). With regard to the implementation of White Book directives concerning the European internal market however, Belgium, in June 1992, occupied the last place. A wide variety of administrative and structural problems were responsible for Belgium's delay in the implementation of EC directives. Late 1992, an urgency programme set up by the Belgian government early 1992 began to succeed in making up for part of the arrearage with regard to the transposition of White Book directives. However, only through the further adaption its political and administrative structures to the actual Europeanization of Belgian political life wilt Belgium become adequately prepared for the timely and correct transposition of EC directives. This implies an active administrative and parliamentary participation in the preparation of EC legislation and an early dissemination of information concerning the EC's legislative process.
