Principle of achievement in the prism of norms legislation on the contract system

In a contractual relationship with the participation of the state, good faith is declared as a necessary norm of behavior both on the part of the state in the person of state customers and on the part of procurement participants. However, the legislator does not develop this principle in existing norms, does not correlate it with other principles of the contract system and does not indicate its criteria. The above not only complicates the implementation of the principle of good faith as a legal regulatory instrument, but also complicates the creation of an understandable law enforcement relationship between the general norms of good faith stipulated by civil law and the special laws of the contract system that declare the good faith of participants in relations.
