If the report of the jury, when accepted, does not increase the damages allowed or diminish the assessment of benefits to the applicant by the committee, the court shall order the applicant for the jury to pay the costs of the application. If such jury, in the reassessment of damages or benefits, increases such damages or diminishes such assessment of benefits, the damages so assessed shall be allowed, with the costs of the application, and paid by the town; and the amount assessed for benefits, less the amount of costs of the application, shall be paid to the town by the person upon whom they were assessed.
