The entry into force of administrative acts

In this study, a distinction between the birth, opposability, applicability and the entry into force of administrative acts, which are the most used measures of administration while engaging in activities related to public service, is tried to be put forward. Also the conditions and the consequences of entry into force are tried to be explained bearing in mind the differences between regulatory and individual acts. The signature and publication theories, which are reflected both in French and Turkish doctrines and jurisdictions, are examined. The rule of law and its sub-principles such as the legal security, right to judicial appeal and respect to vested rights which are indicated in the Constitution of the Republic of Turkey are also taken into account while giving a definition to the concept and indicating the time of entry into force.
