What document must be filed alongside the notice of appeal?

The requirement to file the grounds of appeal alongside the notice of appeal is foundational in the appeal process within New South Wales civil procedure. The grounds of appeal serve as a critical component in outlining the appellant's reasons for challenging the decision of the lower court. This document provides the court with specific legal and factual bases upon which the appeal is claimed, allowing for an efficient examination of the issues presented.

When the notice of appeal is filed, it signals the intention to seek a review of the decision, but the grounds of appeal are necessary to articulate precisely what aspects of that decision are being contested. This clarity is essential, as it helps the appellate court understand the points of contention and addresses them directly in its consideration of the case.

In contrast, while documents like an affidavit about the appeal, a witness statement, or the lower court's verdict may have relevance during the appeal process, they do not fulfill the specific criterion of being mandatory alongside the notice of appeal. Instead, they may be presented later in the process or as supplementary materials depending on the nature of the appeal. Therefore, filing the grounds of appeal is essential for establishing the framework of the appellant's case.
