Did Illinois Hearing Board recommend a six month suspension for violation of Rule 8.4(d) because there is no other rule and this one seems to work as a "catch-all"?

 That's a long title above, but hear me out.  Last July, I reported on a complaint filed in Illinois against a lawyer for his conduct toward courthouse personnel.  The conduct included making inappropriate comments, and advances on female court employees, which could have been defined as harassment.   

However, because Illinois has not adopted a rule like Model Rule 8.4(g), and the current rule related to harassment is ineffective, the disciplinary agency did not really have a rule to support the complaint.  So they did what disciplinary agencies sometimes do when there is no specific rule: they looked for a generic catch-all provision to try to frame the complaint around it.  And they found it in Rule 8.4(d) which relates to conduct prejudicial to the administration of justice.  

In my original post, I argued that this section of the rule was not meant to apply to the conduct at issue in the case.  But, because the Illinois Supreme Court has made it clear that all disciplinary charges must be based on a specific rule, the disciplinary agency was in a bind.  

I recently reported and provided a link to a hearing on whether Illinois should to adopt a rule like Model Rule 8.4(g).  (Go here for my comment on the proposal before the hearing; go here for my report of the hearing.)  Adopting a good version of that rule would provide a rule that would allow for the imposition of discipline in a case like the one of the lawyer harassing court personnel.  

But opponents of such a rule, ironically, will point to the fact that the case was prosecuted under an existing rule as proof that a new rule on harassment is not needed.  

Which brings me to today's post.  The Illinois Hearing Board heard the case as argued under Illinois Rule 8.4(d) and recommended a six month suspension.  Here is the Board's report.

As I have discussed previously (see my posts linked above), the proposed new rule can be improved significantly but it would be more on-point than trying to stretch the reach of the definition of "prejudicial to the administration of justice."

So what do you think?  What is the better choice:  (1) to adopt a new rule (which should be an improved version of Model Rule 8.4(g)), or (2) to reject such a proposal and stretch the meaning of conduct prejudicial to the administration of justice to include pretty much anything a lawyer does that the disciplinary agency can claim affects any aspect of the practice of law?
