The court, when so requested, may in its discretion order and direct the tax collector to cancel such uncollectible personal property taxes. The order shall be entered in the journal of the county court.

(2) If the tax collector determines that additional taxes on real property disqualified from special assessment under ORS 308A.703 are wholly uncollectible due to the property's exempt status, the tax collector may request, in writing, the county court for an order directing that the taxes be canceled. The court, when so requested, may in its discretion order and direct the tax collector to cancel the uncollectible property taxes. The order shall be entered in the journal of the county court.
