Section 117 provides a further legal remedy after the decision of the GST Appellate Tribunal. If either the taxpayer or the GST department believes that the Tribunal's order involves a substantial question of law, an appeal may be filed before the High Court.

A "substantial question of law" means an important legal issue involving interpretation of GST provisions, constitutional validity, jurisdiction, or legal principles. The High Court generally does not re-examine factual findings unless they are clearly perverse or unsupported by evidence. Its primary role is to determine whether the law has been correctly interpreted and applied.

The appeal must be filed within the prescribed time limit from the date of communication of the Tribunal's order. The High Court first decides whether a substantial question of law exists. If satisfied, it formally admits the appeal and proceeds to hear the matter. After hearing both parties, the Court may uphold, modify, or reverse the Tribunal's decision.

The purpose of this section is to ensure uniform interpretation of GST laws across the country and provide judicial oversight over Tribunal decisions.

Example:
The Appellate Tribunal allows a taxpayer's claim for Input Tax Credit based on its interpretation of a GST provision. The department believes that the interpretation is legally incorrect and files an appeal before the High Court under Section 117.

Key Points:

• Appeal lies against Tribunal orders.
• Must involve a substantial question of law.
• High Court mainly examines legal issues.
• Helps ensure consistency in GST law interpretation.

One-Line Summary:
Section 117 allows appeals to the High Court against Tribunal orders involving important legal questions.
