Rules of Professional Conduct
(A) A member shall not threaten to present criminal, administrative, or disciplinary charges to obtain an advantage in a civil dispute.
(B) As used in paragraph (A) of this rule, the term "administrative charges" means the filing or lodging of a complaint with a federal, state, or local governmental entity which may order or recommend the loss or suspension of a license, or may impose or recommend the imposition of a fine, pecuniary sanction, or other sanction of a quasi-criminal nature but does not include filing charges with an administrative entity required by law as a condition precedent to maintaining a civil action.
(C) As used in paragraph (A) of this rule, the term "civil dispute" means a controversy or potential controversy over the rights and duties of two or more parties under civil law, whether or not an action has been commenced, and includes an administrative proceeding of a quasi-civil nature pending before a federal, state, or local governmental entity.
Rule 5-100 is not intended to apply to a member's threatening to initiate contempt proceedings against a party for a failure to comply with a court order.
Paragraph (B) is intended to exempt the threat of filing an administrative charge which is a prerequisite to filing a civil complaint on the same transaction or occurrence.
For purposes of paragraph (C), the definition of "civil dispute" makes clear that the rule is applicable prior to the formal filing of a civil action.
