This article on the usefulness of a general codification of administrative law forms the closing contribution of a NALL-special. In this special, various authors have reflected on the successfulness of a broad codification process in 1998, which introduced rules on the notification of decisions, policy rules, subsidies, enforcement and supervision of administrative authorities in the Dutch General Administrative Law Act (GALA). The editors asked the contributors whether the objectives of the rules introduced were met and how the rules turned out to function in practice. In this overarching article, the NALL-editors reflect on the general lessons to be learned for the GALA-legislator. In these lessons they also take into consideration the initiatives for a law of administrative procedure of the European Union.

This article examines the subsidy rules as they have developed since the introduction of the subsidy title into the General Administrative Law Act (GALA) fifteen years ago. What did experts at that time consider to be the most important parts of the subsidy title and what were their expectations in that regard? We will consider, for certain selected topics, which main developments have taken place in legal practice over the past fifteen years, based mainly on an analysis of the case law. The most important features and trends will be outlined in this article. Finally, we will consider whether these features and trends can teach us anything about (the development of) the GALA that may still be relevant for the legislator today, when designing general rules of administrative law.
