Section 23
SEC. 23. When Rates Payable and Lien— Rates or charges in respect of goods to be landed become payable immediately on landing such goods. Rates or charges in respect of goods to be shipped are payable before the goods are loaded. Rates or charges in respect of goods to be removed from the premises of the Authority are payable on demand. For the amount of rates of charges leviable under this Decree in respect of goods, the Authority shall have a lien on such goods and is entitled to detain then until the amount of rates or charges is fully paid. Such lien shall have priority over all other liens and claims, except claims for duties and taxes due to the Government and expenses of the sale.
