Who Can Appear Before GSTAT: CA, Advocate, GST Practitioner - Rules Compared

Your GSTAT appeal is admitted. The hearing date is approaching. Who should represent you - your regular CA who understands the numbers, an advocate experienced in tribunal litigation, or a GST Practitioner who handles your compliance? The answer depends on the complexity of your case, the nature of the dispute, and the specific rules governing each type of representative at GSTAT. This guide compares all eligible representative categories with their registration requirements, limitations, and strategic advantages.

Section 116 CGST Act: The Statutory Framework

Section 116(2) of the CGST Act, 2017 lists the categories of persons who can be appointed as authorised representatives to appear before GST authorities, including GSTAT. The GSTAT Procedure Rules, 2025 (Rules 72-77) add specific procedural requirements for Tribunal appearances.

Disqualifications: Who Cannot Appear Before GSTAT

• Dismissed or removed from government service - lifetime disqualification.
• Convicted of tax-related offences under CGST Act, IGST Act, UTGST Act, or any law concerning supply of goods/services - indefinite ban.
• Adjudged insolvent - disqualified during insolvency period.
• Found guilty of misconduct - Commissioner may disbar after hearing. This applies to employees, GST practitioners, and retired officers. Does NOT apply to advocates, CAs, cost accountants, or company secretaries (they are governed by their professional bodies).
• Retired officer within 1-year cooling-off - cannot appear until one year after retirement/resignation.
• Conflict of interest - AR who previously represented a client cannot appear against that client in the same or connected case without Tribunal permission.

Changing Your Representative During Proceedings

Under Rule 73, if you want to change your representative mid-case, the new AR cannot be appointed unless (a) written consent of the existing AR is obtained, or (b) an application is filed before the Tribunal and served on the existing AR. The Tribunal decides.

Exception for the Department: The Revenue can change its DR without requiring consent of the previous representative.

Common Mistakes in Representative Appointment

Mistake 1: Not filing FORM-04 before the hearing. Without FORM-04, the representative is not on record. The bench may refuse to hear them.

Mistake 2: Unstamped Vakalatnama. Stamp duty per HC rules applies. An unstamped Vakalatnama is a defect. Check state-specific stamp requirements.

Mistake 3: GST Practitioner signing pleadings without authorisation. GSTPs can represent but cannot sign unless specifically authorised. Ensure the authorisation letter covers signing rights if needed.

Mistake 4: Not checking disqualification before appointment. If your representative was convicted or dismissed, any appearance is void. Verify credentials before engagement.

Mistake 5: Changing representative without proper process. Filing a new FORM-04 without consent of the existing AR or Tribunal permission creates confusion and delays. Follow Rule 73. See our adjournment guide for managing transitions.

Key Takeaways

Section 116(2) CGST Act lists 6 categories of eligible representatives: relative/employee, advocate, CA/CMA/CS, retired government officer, and GST Practitioner. Each files GSTAT FORM-04 with Vakalatnama or authorisation letter.

Advocates are best for complex legal arguments and cross-examination. CAs excel in tax computation and ITC disputes. GST Practitioners handle routine matters. Retired officers bring departmental perspective. Choose based on case complexity.

Disqualifications include dismissal from service, tax convictions, insolvency, and misconduct. The Commissioner can disbar GST Practitioners but not advocates/CAs/CMA/CS (governed by their professional bodies).

Changing representative requires consent of the existing AR or Tribunal permission under Rule 73. The Department is exempt from this requirement.

Conflict of interest bars apply: an AR cannot appear against a former client in the same case without Tribunal permission.
