Liability to pay cost recovery charges for customs officers...

Liability to pay cost recovery charges for customs officers deployed at a Container Freight Station was upheld because the regulatory framework, consistent administrative practice and the petitioner's own prior remittances showed that operators were liable unless expressly exempted. The Court applied contemporanea expositio and substantial compliance, finding that actual customs deployment and supervision satisfied the statutory purpose, and that later internal cadre regularisation did not extinguish the obligation. The challenge was also barred by res judicata and estoppel by conduct, since the liability issue had already been litigated and the petitioner had accepted the levy over time. The remaining quantification dispute was treated as factual and unsuitable for writ jurisdiction, and the cargo movement restriction was sustained as a lawful response to persistent non-payment.
