Shipping bill conversion under customs law needs contemporaneous proof, but stale claims may still be refused as unreasonable delay.

Section 149 of the Customs Act permits amendment or conversion of shipping bills after export if supported by contemporaneous documents in existence at the time of export. A Board circular could not override that statutory power or impose a rigid three-month bar where the Act and Rules contained no express time limit. The request could not be rejected for want of documents where shipping bills, ARE-1 forms and BRCs established the export particulars for the later period, but the remedy still had to be sought within a reasonable time. Conversion was therefore allowed for exports from January 2012 to December 2014, while claims covering 2000 to 2011 were treated as stale.

Issues: (i) Whether free shipping bills could be amended or converted into drawback shipping bills under section 149 of the Customs Act, 1962 despite the absence of an express statutory time limit, and whether the Board circular could impose a three-month restriction; (ii) whether the request for conversion could be rejected for want of documents and for inordinate delay in respect of different export periods.

Issue (i): Whether free shipping bills could be amended or converted into drawback shipping bills under section 149 of the Customs Act, 1962 despite the absence of an express statutory time limit, and whether the Board circular could impose a three-month restriction.

Analysis: Section 149 permits amendment of customs documents even after export, provided the amendment is supported by documentary evidence that was in existence at the time of export. Rule 12(1)(a) of the Drawback Rules also enables a belated declaration where the exporter's failure was for reasons beyond control. The circular relied upon by the department could not curtail the statutory power under section 149, and the absence of an express time limit in the Act or Rules meant that the request could not be rejected merely as time-barred by the circular.

Conclusion: The statutory framework did not permit rejection of the conversion request solely on the basis of the three-month limit in the circular.

Issue (ii): Whether the request for conversion could be rejected for want of documents and for inordinate delay in respect of different export periods.

Analysis: The relevant test under section 149 was whether the documents relied upon were in existence at the time of export, not whether they continued to be retained by the department. The shipping bills, ARE-1 forms and BRCs were sufficient to establish export particulars for the later period. However, while no rigid statutory limitation governed the request, the remedy had to be sought within a reasonable time. On that basis, the application covering exports from January 2012 to December 2014 was held to be within a reasonable period, whereas the later attempt to include exports from 2000 to 2011 was treated as stale and unreasonably delayed.

Conclusion: Rejection for want of documents was unsustainable for the later period, but rejection for the 2000 to 2011 period was upheld for unreasonable delay.

Final Conclusion: The appeal succeeded only in part. Conversion of the free shipping bills for the period January 2012 to December 2014 was allowed with consequential relief, while the request relating to the period 2000 to 2011 remained rejected.

Ratio Decidendi: In the absence of an express statutory limitation under section 149, amendment of shipping bills may be allowed on the basis of contemporaneous documents existing at the time of export, but the request must still be made within a reasonable time; stale claims may be refused.
