Abstract
From the administrative law viewpoint, contracting entities, especially those of a government agency status, may be bound by internal acts issued basing on administrative power. They are usually diversified according to their normativity. Internal normative acts issued by the head of the contracting entity provide for specific rules of conduct of an abstract nature which are to be complied with by their addressees in the prescribed situations. On the other hand, internal acts which are not normative are of one-off use. A common trait of internal acts in a contracting entity is that the norms they contain may be addressed solely to the unit organizationally subordinated to the issuing entity. The application of such internal acts is not fully left to the discretion of the head of a contracting entity. With respect to the legal bases authorizing their issuance, the above acts may be divided into obligatory and facultative ones. Considering the fact that the basic form of acts issued by the head of a contracting entity is a regulation, it should be postulated that in practice those acts should comply – both materially and formally – with the requirements of the lawmaking technique.
