Personal hearing mandate in tax proceedings: failure to afford hearing requires reconsideration and a reasoned decision.

Section 75(4) of the UPGST Act mandates that an opportunity for personal hearing be granted either upon a written request by the person chargeable with tax or penalty or whenever an adverse decision is contemplated; the disjunctive word "or" must be given its plain meaning, creating independent triggers for the hearing obligation. The court concluded the authorities failed to comply with this requirement and directed that a personal hearing be afforded and a reasoned order issued thereafter to ensure procedural fairness in tax adjudication.
