(1) It is the duty of a lawyer, whilst acting with all due courtesy to the Court or Tribunal before which he is practising, fearlessly to uphold the interests of his client without regard to any unpleasant consequences either to himself or to any other person. In particular, no lawyer is bound to withdraw any charge which is the necessary outcome of material facts sworn to by or on behalf of his client unless expressly instructed so to do by his client. A lawyer shall not however deceive the Court or Tribunal before which he is appearing in any circumstances whatsoever.

(2) A lawyer shall not appear as witness for his own client except as to merely formal matters such as the attestation or custody of an instrument, or the like, or when it is essential to the ends of justice. If he is a necessary witness with respect to other matters, the conducting of the case should be entrusted to another lawyer.

(3) Once a lawyer has accepted a brief he shall not relinquish it to the detriment of his client without good and sufficient cause.
