If an appraiser testifies in court that they could not confirm a sale with the buyer and seller because they could not find them, but the opposing attorney's appraiser, did, in fact, track down a buyer or seller just because they happened to know them personally, and obtain information that the other appraiser said they could not get "in the normal course of business"....do you think the judge isn't going to weigh one over the other? And if it was a critical error - say the first appraiser assumed the interior condition was average - but the latter appraiser found out the place was trashed - do you think the first appraiser's lawyer has a case to send to the board?
And will the board say they didn't do their due diligence (try harder next time)? Or will they say they should have withdrawn from the assignment (competence)? Or will the board give them a 'bye' on the issue (we accept that you could not find the info out)?
