The document discusses the EU public procurement rules regarding colleges procuring services from third party organizations, even if those third parties are other colleges or entities established by the procuring college. Case law has shown the procurement rules still generally apply, unless the third party carries out most of its work for the procuring college, the college exercises the same control over the third party as its own departments, and there is no private ownership of the third party. These are known as "Teckel exemptions". The document also notes that legal firm Eversheds prepared a report for AoC on sharing services in education that reviews models for VAT exemption while considering governance, procurement, and other legal issues.
