Locus standi limits: only aggrieved private parties may challenge tax notices; third-party appeals are not maintainable.

Only the private operators against whom tax notices are issued possess the requisite standing to challenge those notices; third parties lack authority to prosecute appeals or writs on their behalf, and challenges must be instituted by the directly aggrieved parties through the statutory remedy, who may then raise all issues available to them in accordance with law.
