165.Section 189 largely follows section 173(1) to (3) in Chapter I, in providing for regulations to set out the enforcement requirements for licensing schemes. Subsection (3) makes the occupier of a premises liable to pay parking levy penalty charges but allows the Secretary of State or NAW to specify other persons in certain circumstances. Subsection (4) enables the regulations to specify arrangements for adjudication and enforcement of licensing schemes. Section 190 allows for a right of entry to premises by an authorised official to check that workplace parking is appropriately covered by a licence. It also creates an offence of intentionally obstructing an authorised official in the exercise of these powers.
