“(1) An application may be made to the appropriate tribunal for a determination whether a service charge is payable and, if it is, as to – (a) the person by whom it is payable, (b) the person to whom it is payable, (c) the amount which is payable, (d) the date at or by which it is payable, and (e) the manner in which it is payable.”
“The tribunal has decided the issues in principle and the respondent is required to determine the consequent figures as the respondent did not have the relevant figures available during the hearing.”
