1.5.1 You are the agent of your client and must have the authority of your client for your actings. You must not accept improper instructions, for example to assist a client in a matter which you know to be criminal or fraudulent, but you may properly advise on the legal consequences of a proposed course of action or on the scope or application of the law to particular circumstances.

1.5.2 You may decline to accept new instructions, whether from a new or established client, without giving a reason for doing so, provided the refusal to act is not motivated by discrimination in breach of rule 1.15.
