Judgment :- 1. The short question arising in this appeal turns on the interpretation of S.153 of the Customs Act, 1962 which is in these terms: "153. Any order or decision passed or any summons or notice issued under this Act, shall be served (a) by tendering the order, decision. Summons or notice or sending it by registered post to the persons for whom it is intended or to his agent; or (b) if the order, decision, summons or notice cannot be served in the manner provided in clause (a), by affixing it on the notice board of the customs house". The learned judge dealt with the contention in the following manner in the judgment under appeal. "What is contended for by the petitioner is that before the Department could have taken recourse to sub-clause (b) of S.153 they should have tried to serve the order in both manners contemplated by sub-section (a). Shri N. N. Divakaran Pillai, the petitioner's counsel contends that if it was not possible to serve the petitioner by sending the order by registered post, he should have been served by tendering it directly. I do not agree with this contention. If the order or decision passed by the Customs Authorities could not be served in one of the modes as prescribed in sub-clause (a) then the Authorities could certainly have recourse to sub-clause (b). Moreover, if the petitioner was evading service of the order sent by registered post, it would have been impossible to tender the order to him directly. In the circumstances, there is nothing illegal in the action taken by the Customs Authorities concerned". We only wish to add that the modes provided in S.153(a) are alternative methods by which attempts can be made to serve an order or decision passed or any summons or notice issued under the Act. Whether it should be tendered or sent by registered post or should be served on the agent would depend upon the feasibility of effecting service by one of the methods. It is normal to send such notices by registered post. That method was attempted but failed. In such circumstances S.153(b) of the Customs Act, 1962 could be brought into effect. That is what has been done. 2. It is normal to send such notices by registered post. That method was attempted but failed. In such circumstances S.153(b) of the Customs Act, 1962 could be brought into effect. That is what has been done. 2. Counsel for the appellant relied on two rulings of the Allahabad High Court in C. Maharaj & Sons v. Sales Tax Officer, IV, Agro and others (1964) 15 S.T.C. 879 and Gopal Das Uttam Chand v. Sales Tax Officer, Dehra Dun (1970) 25 S.T.C. 229 interpreting R.77 of the U.P. Sales Tax Rules, 1948 in support of his contention that all the modes under S.153(a) should be exhausted before S.153(b) is resorted to. The rule interpreted in those decisions is differently worded. We do not think that the decisions are helpful in understanding S.153 which we have to interpret in this case. The wording used in the rule interpreted in those decisions was "if none of the methods indicated is available" service may be effected by affixture. There is no such provision in S.153(b) of the Customs Act. We think the methods indicated in S.153(a) are alternative methods any one of which could be attempted in the first instance. The different modes of service provided by the rule also support the view; either tendering to the person (apparently when it is feasible) or attempting to serve on his agent (apparently when one is available) or by sending by registered post To say that an attempt to tender notice must be made in cases where it is not feasible or even possible or that an attempt should be made to serve on an agent when there is no agent or none is known to exist would be to make the section unworkable. 3. We see no reason to interfere. We dismiss this appeal but direct the parties to bear their respective costs. Dismissed.
