This contribution scrutinizes the effect of the General Administrative Act (Algemene wet bestuursrecht) on the doctrine of administrative supervision (bestuurlijk toezicht), especially on the (governmental) power of spontaneous annulment (spontane vernietigingsrecht) towards local authorities. In 1998 the legal provisions concerning administrative supervision have been transferred from the Local Government Act (Gemeentewet) to the General Administrative Act. Since then the doctrine was subject to several major changes, from which the 2006 Policy document on spontaneous annulment (Beleidskader spontane vernietiging) and the 2012 Act on re-vitalizing general supervision (Wet revitalisering generiek toezicht) are the most important. The provisions from the General Administrative Act concerning administrative supervision have hardly been changed; case law concerning spontaneous annulment mainly concerned the interpretation of the Policy documents. The provisions regarding administrative supervision and laid down in the General Administrative Act, can therefore be seen as of constant value of administrative supervision.

In 1998 a chapter on administrative enforcement was added to the GALA (in the so-called third Tranche). This contribution reflects on the legislative aims of this Tranche; to what extent these aims have been attained and what important developments have occurred since. As the third Tranche has led to little reform, a brief review will suffice. The developments after the third Tranche are discussed extensively, concerning both the third Tranche - amongst others the obligation in principle to enforce ('beginselplicht tot handhaving') - and reparatory sanctions since the fourth Tranche (2009), which amongst others regulated the execution of administrative reparatory sanctions and added regulation on administrative fines (a punitive sanction). Additionally, more general provisions of administrative law enforcement are discussed. The development of administrative enforcement are reflected against general developments in administrative law, such as harmonization and the increase of litigation. Lastly some bottlenecks will be noticed and solutions proposed.

Article 3:41 General administrative law act reads: Orders which are addressed to one or more interested parties shall be notified by being sent or issued to these, including the applicant. If an order cannot be notified in that manner, it shall be notified in any other suitable way. This article examines the extent of 'any other suitable way' and whether the objectives of the legislator have been achieved.
