Summons powers in tax assessment can be used to obtain postal records, while direct mandamus against postal authorities is unavailable.

Postal records relating to parcels posted by a dealer and later returned were protected from direct disclosure, subject to the limited exception permitting postmasters to furnish information when called for in writing by the assessing authority exercising summons powers. A direct writ of mandamus against the postal authorities was therefore unavailable, because the statutory route for obtaining the information lay through the assessment authority. The assessing authority, acting under its power to summon witnesses and require documents in quasi-judicial sales tax proceedings, could be directed to seek the postal particulars through the prescribed summons process so that assessment could proceed fairly.

Issues: (i) Whether the postal authorities were bound to furnish information relating to parcels posted by the dealer and later returned. (ii) Whether the assessing authority could be directed to use its summons power to obtain the required postal information for completion of the assessment.

Issue (i): Whether the postal authorities were bound to furnish information relating to parcels posted by the dealer and later returned.

Analysis: The relevant postal rule contained a prohibition against disclosure of post office records to persons not entitled to inspect them, but exception 4 to rule 17 permitted postmasters and sub-postmasters to furnish information when called for in writing by an Income-tax Officer or Sales Tax Officer exercising civil court powers in relation to summoning and examination of persons. The Court held that the postal authorities could not be compelled by mandamus in the manner sought, because the statutory exception provided a lawful channel for obtaining the information through the assessing authority.

Conclusion: The claim for a direct writ against the postal authorities was rejected.

Issue (ii): Whether the assessing authority could be directed to use its summons power to obtain the required postal information for completion of the assessment.

Analysis: The assessing authority had power under section 54 of the Tamil Nadu General Sales Tax Act to summon witnesses and require production of documents, and for that purpose could exercise powers akin to those of a civil court under the Code of Civil Procedure, 1908. Since assessment proceedings are quasi-judicial and must be conducted with a fair opportunity to the dealer, the Court considered it proper to issue directions enabling the assessing authority to obtain the postal particulars through summons rather than grant the writ in the form sought.

Conclusion: The assessing authority was directed to issue summons to the concerned postmaster for the particulars listed by the petitioners.

Final Conclusion: The writ petitions failed on the main prayer for mandamus, but the assessment authority was left under a duty to facilitate production of the relevant postal information through the statutory summons procedure so that the assessment could be completed fairly.

Ratio Decidendi: Where a statutory assessing authority has express summons powers and the proceedings are quasi-judicial, the Court may refuse direct mandamus against a third party and instead require the information to be obtained through the prescribed statutory process to secure a fair hearing.
