Under what condition may a reviewer use previously unavailable information to critique the work of the original appraiser?

In the realm of appraisal practices, the integrity and reliability of the appraisal process hinge on the principles of transparency and maintaining a level playing field for all parties involved. The correct understanding here is that a reviewer is not permitted to use previously unavailable information to critique the work of the original appraiser.

This is grounded in the ethical standards of appraisal practice, which emphasize that a reviewer should base their critique solely on the information that was accessible to the original appraiser at the time of their report. Utilizing new information that the original appraiser couldn't have considered undermines not only the appraisal's credibility but also the foundational principles of fairness and consistency in the review process.

By adhering strictly to this guideline, the appraisal profession ensures that reviews remain objective and fair, reflecting the appraisal based on the circumstances and information available at the time of the original report. This also promotes the notion that appraisers are evaluated on the same information, thereby fostering trust in the appraisal process.
