USPAP is about appraiser conduct. What the appraiser actually did or didn't do.
If public records has an error the source of that error is in the public records. MLS, building permits, surveys, title reports, termite reports, whatever - none of those data sources can be considered perfectly accurate on the 100% basis.
If an appraiser uses that information there is still an error, but the appraiser isn't the one who made the error. It's a standard assumption that we assume the information being used is true and correct, and we explicitly assert that in our SR2-3 certifications. "to the best of my knowledge and belief".
Where the definition of "misleading" that they were using becomes a problem is that "...unintentionally misrepresenting, misstating..." clause. There is a misstatement, it was unintentional on the appraiser's part, it is often beyond the control or the knowledge of the appraiser but under this definition it could still be attributed to them by someone acting in bad faith.
As an illustration of the controversy,
djd09 has USED that definition - in bad faith - many times on this forum to say that if a 3rd party inspection has an error and the appraiser relies in part on that information in a desktop SOW assignment then the appraiser was "misleading". His interpretation of it is that the appraiser is 100% responsible for the accuracy of the data regardless of its cause or source.
Regardless if the ASB ever intended the term to be interpreted that way, the manner in which it was worded enabled djd09 and others who want to act in bad faith and under the logical disconnect to use it that way despite the open, notorious and universally accepted common sense reality that appraisers use imperfect data all the time. In spite of the fact that appraisers qualify their usage of the information by disclosing "to the best of my knowledge and belief". Despite the point that it's impossible to perform any appraisal without the use of assumptions in lieu of certainty with some of this data. If we had to be 100% certain of every fact in support of an appraisal we wouldn't be able to complete any assignment.
That's why some appraisers disagreed with the manner in which that definition was worded. And as it turns out that includes at least some of the appraisers serving on the ASB.
