What type of review is a new and complete review of the appealed issue with no deference given to the decision being appealed?

The term "de novo review" refers to a legal standard in which a court or tribunal re-examines an issue without reference to the conclusions or decisions made previously. This means that all aspects of the case, including evidentiary materials and legal arguments, are assessed fresh without any bias or consideration for the prior rulings. In this context, when an appeal is under a de novo review, the reviewing authority is essentially starting from scratch.

This approach is particularly important in scenarios where the parties believe that a decision made in the previous review was incorrect or not fully justified based on the evidence presented. By employing a de novo standard, the reviewing authority ensures a fair re-evaluation of the matter at hand, potentially leading to a different conclusion or outcome based on the same or additional information.

The other types of reviews mentioned, such as secondary review, original review, and clear and unmistakable error, involve different methodologies or standards and typically do not embody the comprehensive reevaluation that characterizes a de novo review.
