The Fifth Circuit found that the rule of lenity applied in a disciplinary proceeding involving this Louisiana ethics rule:
A division of fee between lawyers who are not in the same firm may be made only if: (1) the client agrees in writing to the representation by all of the lawyers involved, and is advised in writing as to the share of the fee that each lawyer will receive; (2) the total fee is reasonable; and (3) each lawyer renders meaningful legal services for the
client in the matter.
It concluded that the rule was ambiguous when applied to successive rather than simultaneous counsel. In re Andry, No. 22-30231 (Nov. 29, 2022). The panel later granted rehearing and issued a revised opinion.
