Correct Answer:
B. Occupier/Aggrieved person
The power to call records from other departments allows the Hearing Officer (HO) to check the veracity of the claim of the Occupier/Aggrieved person. In a representation, the occupier or aggrieved person is typically challenging an enforcement action or asserting their rights over a property. The HO's role is to impartially adjudicate these claims, and accessing records from other departments helps verify the factual basis of their assertions, counter-claims, or the legitimacy of their occupation. While the EO provides initial reports, the HO's independent verification focuses on the claims made by the party directly affected by the enforcement.
