La dernière étude de l'Institut européen d'administration publique (IEAP) "The Institutional Impacts of EU Legislation on Local and Regional Governments, A Case Study of the 199/31/EC Landfill Waste and 2004/18/EC Public Procu
rement Directives", dénonce notamment le fort recours au droit indicatif: "using soft law to regulate very important aspects of the Directive is another important shortcoming: it is not possible to foresee the institutional impact of soft law” (recourir au droit indicatif pour réglementer des aspects très importants de la directive, voilà qui
constitue une autre faille ...[+++] importante: il n'est pas possible de prévoir les incidences institutionnelles du droit indicatif).
The most recent study produced by the European Institute of Public Administration (EIPA), ‘The Institutional Impacts of EU Legislation on Local and Regional Governments, A Case Study of the 1999/31/EC Landfill Waste and 2004/18/EC Public Procurement Directives’, criticises the extensive use of soft law: ‘using soft law to regulate very important aspects of the Directive is another important shortcoming: it is not possible to foresee the institutional impact of soft law’.
