RPC 8.4(c), which proscribes dishonest conduct.Accord In re Uchendu , 812 A.2d 933, 936 (D.C. 2002) (finding that an attorney who submitted false signatures and notarizations to the court made a false statement under RPC 3.3(a) and acted dishonestly under RPC 8.4(c) ); In re Rodriguez , 177 Wash.2d 872, 306 P.3d 893, 896-97 (2013) (finding violations of RPC 3.3(a)(1) and 8.4(c) when an attorney submitted documents to the Board of Immigration Appeals that the attorney knew to contain a false signature).
