Additional evidence before the appellate authority under Rule 112
The document you did not file below can still be filed, but only through the right door and with the right explanation.
Rule 112 restricts the production of additional evidence before the Appellate Authority. Evidence not produced below may be admitted where the adjudicating authority refused to admit it, where the appellant was prevented by sufficient cause from producing it, where it was not within his knowledge or could not be produced despite due diligence, or where the adjudicating authority passed the order without giving sufficient opportunity to adduce it. The Authority must record reasons for admitting it, and the other side must be given an opportunity to examine it.
The four gateways
Refusal below. Where the adjudicating authority declined to admit the evidence. Produce the record of the refusal.
Prevented by sufficient cause. The cause must be specific and documented, and it must explain the whole period.
Not within knowledge, or not producible with due diligence. This is the gateway for third party documents obtained later, and the due diligence must be shown.
No sufficient opportunity. Where the order was passed without giving time to adduce the evidence, which overlaps with the Section 75(4) ground and is often the strongest route.
How to file it
A separate application, expressly under Rule 112, identifying each document and the gateway relied on for it. A single omnibus application for a bundle invites a single rejection.
An affidavit setting out the circumstances, with the supporting record.
The documents themselves, paginated, marked and indexed, so the Authority can see what it is admitting.
Do not embed new documents in the appeal record without an application. Where the order is later challenged, the absence of the application becomes the department's answer.
The better approach
Plan the evidence at the adjudication stage. An appellate authority is not obliged to admit evidence, and a case built on documents produced for the first time in appeal is weaker even when they are admitted.
Where a document cannot be obtained in time, say so in the reply, identify the document, and record the steps taken to obtain it. That contemporaneous statement converts a later application from an afterthought into a continuation.
Where the adjudicating authority refuses time, get the refusal on the record. It creates both the Rule 112 gateway and the natural justice ground.
What to do on Monday
Identify the evidence you cannot obtain, in the reply itself, with the steps taken.
Get any refusal of time or of documents recorded at the adjudication stage.
File a document wise Rule 112 application with the gateway stated for each item.
Weigh the remand risk before filing evidence that changes the factual basis of the case.

Write to the GST practiceQuestions we are asked on this
Can we file additional evidence before the Tribunal?
The Tribunal's own procedure governs, and it similarly requires an application with an explanation. Do not assume a free hand.
Is a chartered accountant's certificate additional evidence?
A certificate prepared after the order, on facts already on record, is often treated as a working rather than evidence. Frame it that way and annex the primary documents.
Will the department get to respond?
Yes. The rule requires an opportunity to examine the evidence, and that will usually mean a remand risk. Weigh it.
What if the document is decisive?
Then apply properly and explain the delay fully. A decisive document with a candid explanation is usually admitted.
Does the Authority have to record reasons?
Yes, for admitting additional evidence, and the absence of reasons is a ground in the further appeal.
