When department heads wish to bring some person to the campus to serve as guest lecturer/consultant in their field of specialization, the approval of the President, the Vice President for Business and Administration, or the Director of Contract Administration must be secured prior to any commitment. The request for such services must be submitted using appropriate forms. An appropriation may not be expended to pay for consulting services in excess of $10,000 until the Governor has made a finding of fact that a need exists for the services. A department or agency may not enter into a consultant contract with any individual who has been previously employed by the department or agency within the past twelve months.
