The duty arises when the notice contains the requirement to attract the subjects of small business (SSB) or the socially oriented non-profit organizations (SONPO) as subcontractors (collaborators). Earlier the Ministry of Economic Development had an opposite point of view.
To be necessary to note: in the Law N 44-FL it is provided that the customer has the right to demand to attract SMP or SONO as subcontractors (collaborators) if the supplier (the contractor, the performer) isn't such subject or the organization.
