'Concealed purchase' as a form of inspection control

'Concealed purchase' is a new form of inspection control, introduced into our legal system in December 2018, by the Law on Amendments to the Law on Inspection Control. It is, actually, a specific method of proving during the inspection control process, used in the case of reasonable doubt regarding unregistered activity by the controlled subject. It can be also used when the controlled subject does not issue a receipt. In both cases, this method can only be used if necessary evidence can not be otherwise provided or if it would be significantly more difficult. This method is specific because of the fact that inspectors collect the relevant evidence and facts by direct observing. It is called 'concealed purchase' because official identity card and the inspection control warrant are shown to the controlled subject, by the inspectors, only after the 'purchase' is done.
