How did the opinion assess a free-living-will seminar ad calling living trusts 'revolutionary' and 'risk-free'?

1995

No. The opinion said that fee category was available only to lawyers who neither resided nor practiced in Missouri.

1995

Could a Texas lawyer negotiate from Texas with an insurer about a Missouri accident without a Missouri license?

1995

Under this historical opinion, could counsel contact former employees whose conduct might be imputed to an opposing party?

No. Relying on Pitts and Rule 4-4.2, the opinion treated employee function, rather than current or former status, as decisive. The official source warns that former-employee rule guidance later…

No. The opinion found a conflict that could not be waived because the dispute involved governmental entities and officials.

1994

Did a Social Security contingent-fee ad need Rule 4-7.2's expense disclaimer when clients would not owe expenses after an unsuccessful case?

Yes. The opinion required the rule's disclaimer despite that arrangement and allowed an additional explanation of Social Security law and the client's actual expense obligation.

1994

Could a former judge returning to law practice state retired-judge status on cards or letterhead?

Yes under this lawyer-ethics opinion. It expressly declined to decide the Code of Judicial Conduct question and directed inquiry to the judicial commission.

1994

Did former status alone permit ex parte contact with an opposing party's employees under this historical opinion?

No categorical answer followed from former status alone. The opinion applied Rule 4-4.2's comment and Pitts rather than a current-versus-former distinction; the official page warns that guidance…

1994

The opinion identified no professional-rule ban on the contact. It said jurors had no duty to speak or cooperate and warned against conduct or questioning that might be viewed as harassment.

1994

Did a lawyer's free legal book and offer letter count as advertising, and when was a disclaimer needed?

1994

Could a lawyer pay for a business-association directory listing that described practice areas without claiming specialties?

1994

Could a lawyer's certified-mail service cover letter explain the effect of action requested from an unrepresented opposing party?

1994

1994
