In addition to the functions the Minister assumes under section 383 of the Act, the Minister may, to the extent the Minister believes such action to be justified by the need to optimize resources and after consulting with the public or private institution under agreement concerned, oblige such an institution to use the services of a joint procurement group or to participate in a call for tenders held by such a group.
