Introduction:
The Andhra Pradesh High Court in the case of M/s. Mahadev Transport And Contractors v. Assistant Commissioner and Others (Writ Petition No.16500 of 2025 and batch) examined a significant issue under the Goods and Services Tax (GST) regime—whether assessment orders issued without the mandatory Document Identification Number (DIN) could be treated as void or merely invalid. A Division Bench comprising Justice R. Raghunandan Rao and Justice Sumathi Jagadam clarified that such orders are not void ab initio but only invalid, meaning they continue to remain in force unless explicitly set aside by a competent court or authority. This ruling carries far-reaching implications for businesses challenging GST assessments on technical grounds and clarifies the legal distinction between void and invalid orders under tax law.
Arguments on Behalf of the Petitioners:
The petitioners, all registered under the GST regime, filed writ petitions challenging their respective assessment orders on the sole ground that the orders did not bear the mandatory Document Identification Number (DIN) as required by CBIC circulars. The petitioners, represented by their counsel, argued that Section 168(1) of the CGST Act empowers the Central Board of Indirect Taxes and Customs (CBIC) to issue instructions or directions, which are binding on all GST officers. Pursuant to this power, CBIC had issued circulars mandating that all communications, proceedings, and orders must necessarily bear a DIN. Further, the circular categorically stated that any communication not bearing such DIN would be deemed invalid and considered to have never been issued. On this basis, the petitioners argued that their assessment orders, lacking a DIN, were void orders and complete nullities in the eyes of law. They contended that once an order is void, it is as if it never existed, and therefore, no action for tax collection or enforcement could be sustained on the basis of such orders. In such cases, fresh assessments would be required.
The petitioners further argued that the question of delay or laches in approaching the court would not arise because once an order is void, it cannot be cured by passage of time. According to them, a void order is a “dead letter” incapable of revival or validation, and hence, the delay in filing petitions could not be a ground for denying them relief. They also asserted that their delay was due to practical difficulties in accessing the orders uploaded on the GST portal, and in some cases, they were not immediately aware of the existence of such orders. The petitioners urged the Court to hold that the absence of DIN rendered the assessment orders legally non-existent and therefore liable to be quashed.
Arguments on Behalf of the Respondents:
The State authorities, represented by counsel for the respondents, defended the validity of the assessment orders, though acknowledging that they did not carry a DIN. They argued that the circulars issued by CBIC are binding only on the tax authorities and not on taxpayers, and their violation may render an order invalid but not void. An invalid order, the respondents argued, remains enforceable until it is set aside by a competent court or authority, whereas a void order is a nullity from inception. According to them, the language of the circulars only stipulates invalidity and does not declare such orders void. Thus, taxpayers could not treat such orders as non-existent.
The respondents further submitted that since the petitioners had admittedly received the orders through the GST portal, they could not claim ignorance or lack of service. The CGST Act and Rules specifically recognize electronic service of orders through the portal as valid service. The argument that lack of DIN amounted to no service was therefore untenable. The State strongly opposed the petitioners’ contention that delay was immaterial, submitting that even invalid orders continue to remain effective until quashed. Therefore, it was incumbent upon the petitioners to challenge them expeditiously. The respondents argued that entertaining writ petitions filed after inordinate delay would open floodgates for challenges against assessment orders passed years ago, undermining certainty and finality in tax administration. They contended that most petitions involved orders from 2023, and the plea of ignorance was an afterthought to justify delay. The respondents urged the Court to dismiss the petitions both on merits and on grounds of laches.
Judgment of the High Court:
After a detailed examination of the rival submissions, the Andhra Pradesh High Court delivered a nuanced ruling clarifying the legal effect of assessment orders issued without DIN. The Division Bench first examined Section 168(1) of the CGST Act, which empowers CBIC to issue orders, instructions, and directions to tax officers. The Court held that such instructions are binding on the authorities and violation of such instructions can render an order invalid. However, the Court clarified that such violation cannot render an order void ab initio unless the Act or the Rules themselves expressly so stipulate. The circulars, while binding on officers, could not elevate the absence of DIN to the level of statutory nullity.
The Court observed that the circulars mandated that communications without DIN would be treated as invalid and deemed never issued, but such a stipulation was only in the nature of administrative guidance binding on authorities. For taxpayers, the absence of DIN could only render the orders vulnerable to challenge but not automatically void. Hence, assessment orders without DIN were not void but only invalid. They would remain effective and enforceable unless specifically challenged and set aside by a competent forum.
Rejecting the petitioners’ contention that absence of DIN amounted to absence of service, the Court noted that the CGST Act and Rules explicitly recognized electronic service through the portal as valid service. Since the petitioners had access to the portal, they could not claim ignorance of the orders merely because they were unaware or negligent in checking the portal. The Court further stressed that condoning such excuses would open the floodgates for belated challenges to assessment orders, defeating the principle of finality in tax administration.
On the issue of delay, the Court held that the petitions were barred by laches. Most of the challenged orders were from 2023, and the petitioners had not provided any satisfactory explanation for the delay. The plea that a void order could be challenged at any time was rejected because the Court had already held that such orders were not void but merely invalid. Once an order is invalid, it continues to remain in force until set aside, and therefore prompt challenge is required. The Court emphasized that registered taxpayers could not shirk responsibility by claiming they were unaware of orders uploaded on the official portal, which is an accepted mode of service under the Act.
Accordingly, the High Court dismissed all the writ petitions, holding that the assessment orders without DIN were not void but invalid, and in the absence of timely challenge, they continued to remain in force. The ruling thus clarified the position of law: non-compliance with CBIC circulars on DIN does not make orders void ab initio, though it can make them invalid and open to challenge within a reasonable time. This clarification upholds the balance between ensuring adherence to administrative instructions and preserving the finality of tax assessments.
