To answer your first question...Nowhere. I have never said a word about whether or not it is appropriate for "a judge to rent, lease, or sublet an office that they can not practice law from to another lawyer?"
Don't know if you read any of the prior posts or not, but the issue I have is with her not disclosing this fact on the record, when her renter is going before her. She should only have two ethical choices:
1. Fully disclose the financial conflict of interest on the record
2. Assign the case to another Judge or offer to recuse herself
What has been practiced up to this point is to not disclose the conflict of interest to anyone on the record and hope that no litigants find out before, during, or after the trial. Then if they do find out, hope that nobody will appeal based upon this. If they do appeal, most appellate attorneys would have trouble arguing an ethical issue about Abrams to her husband's colleagues in Annapolis at MDCOSA. Even attempting to do this would most likely not bring good results to the client or the attorney's career.
So in reality, you're only real shot at the proper administration of justice, in a case where Guenther is the opposing attorney, and you're judge is Karen H. Abrams, is for Abrams to disclose the relationship on the record at some point before trial starts. Then a litigant could file a motion for recusal (if the judge has not already offered to recuse), or the litigant could ask for a change of venue, etc.
If what I have stated is not "telling it like it is", then someone with more legal knowledge please step up and say so. Up to this point, I've only heard political spinning, and a few light attempts to attack the issue from a legal standpoint.
