Customs shipping bill conversion: no implied limitation period, Limitation Act inapplicable, and circulars cannot override the statute.

Section 149 of the Customs Act permits conversion of shipping bills on documentary proof and does not itself prescribe a limitation period. The three-year restriction could not be read into the provision, and Article 137 with section 29(2) of the Limitation Act was held inapplicable to conversion proceedings before a tribunal or quasi-judicial authority. A circular cannot impose a restriction inconsistent with the statute, so Clause 3(e) of Circular No. 36/2010-Cus. could not justify refusal of conversion. The discussion also notes the relevance of merger and finality in preventing collateral challenge to an earlier conversion order.

Issues: (i) Whether a time limit of three years could be read into section 149 of the Customs Act, 1962 for conversion of shipping bills from one export promotion scheme to another. (ii) Whether Article 137 of the Limitation Act, 1963 and section 29(2) of the Limitation Act, 1963 apply to such conversion proceedings before a tribunal or quasi-judicial authority. (iii) Whether Clause 3(e) of Circular No. 36/2010-Cus. could justify refusal of conversion where the statutory provision did not impose such restriction.

Issue (i): Whether a time limit of three years could be read into section 149 of the Customs Act, 1962 for conversion of shipping bills from one export promotion scheme to another.

Analysis: The governing provision permits conversion on the basis of documentary evidence and does not prescribe any limitation period. The earlier tribunal ruling had already held that importation of a three-year restriction into the provision was unsustainable. Once the conversion was found beneficial to the exporter and supported by documentary proof, the absence of a statutory time bar controlled the matter.

Conclusion: The three-year restriction could not be imposed and the conversion could not be rejected on that ground.

Issue (ii): Whether Article 137 of the Limitation Act, 1963 and section 29(2) of the Limitation Act, 1963 apply to such conversion proceedings before a tribunal or quasi-judicial authority.

Analysis: The applicable limitation principles under the Limitation Act govern proceedings in courts, not proceedings before tribunals or quasi-judicial authorities unless the special law expressly attracts them. On that basis, Article 137 and section 29(2) were held inapplicable to conversion requests made under section 149 of the Customs Act, 1962.

Conclusion: Article 137 and section 29(2) of the Limitation Act, 1963 did not apply to the conversion proceedings.

Issue (iii): Whether Clause 3(e) of Circular No. 36/2010-Cus. could justify refusal of conversion where the statutory provision did not impose such restriction.

Analysis: A circular cannot create a restriction that is absent from the statute. The order also proceeded on the footing that the earlier conversion order had attained finality and had merged in the tribunal's prior decision, so the department could not reopen the issue through a collateral challenge. The doctrinal support relied on merger and finality of adjudication.

Conclusion: Clause 3(e) of the circular could not override section 149, and the objection based on the circular failed.

Final Conclusion: The appeal failed because the statutory scheme permitted the conversion, the general limitation provisions were inapplicable, and the departmental objection based on the circular could not defeat the conversion already sustained in earlier proceedings.

Ratio Decidendi: Where a special customs provision permits conversion on documentary proof without prescribing a limitation period, general limitation rules for courts cannot be imported to tribunal proceedings, and a circular cannot add a restriction inconsistent with the statute.
