The Maryland Attorney Grievance Commission has charged Montgomery County State's Attorney Douglas F. Gansler with violating the rules of professional conduct, citing his proclivity to "entertain press conferences" that run afoul of pretrial publicity standards. The media-friendly Gansler yesterday denied any wrongdoing, calling the charges "ridiculous" and "a waste of time." The case, filed this week, will be heard by a Circuit Court judge. The Court of Appeals will then review the lower court's findings and has the ultimate say over whether to punish a lawyer.
