[You, leading with your chin] Unsubstantiated accusations.
Not really. Get your lawyer or librarian boot Lexis/Nexis and pull up, searching on Miers's law firm and Lomas & Nettleton, a Texas state case decided in IIRC 1995 in the state district court in Texarkana.
The opinion in that case is substantive, not "unsubstantiated", and the allegations of improper conduct with respect to a client's property, and the opinion of the court in granting in part a motion by Lomas's new counsel for summary judgment, add up to specific and substantial accusations borne in and found true.
There are a couple of cases at the U. Mich site, but from your desctiption of the TX case, I don't believe it appears in that list.
