Full text
3.05.18. An advocate shall notify the client of any fact learned by him in the performance of his professional services which, in the advocate’s opinion, may be a breach of the law by the client.
If the client is not a natural person, the advocate shall give such notification to the representative of the client with whom the advocate deals when providing his professional services. If the advocate later becomes aware that the client has not remedied the unlawful situation, he shall notify the appropriate hierarchical authority when the situation involves:
(1)  a material breach of securities law or any law for the protection of security holders or members of a partnership or legal person; or
(2)  a breach of any other law, if it is likely to lead to serious consequences for the client.
O.C. 351-2004, s. 47.
