Have just found what I asked for at the Law Institue of Victoria (Australia).
Professional Ethics
A legal practitioners professional duties fall under three main headings. These are : the duty to the law, the duty to the court, and the duty to the client. The legal practitioner is closely associated with, and is part of the administration of the law. The legal practitioner should always uphold the law and this obligation is paramount.
The general principles of professional conduct are further outlined in Section 64 of the Legal Practice Act 1996. The Legal Practice Act 1996 identifies the following general principles of professional conduct :
In the service of a client to act honestly and fairly in the clients best interests.
Not to engage in, or assist, conduct that is calculated to defeat the ends of justice or is otherwise in breach of the law.
To act with all due skill and diligence.
To act with reasonable promptness.
To maintain a clients confidences.
To avoid conflicts of interest.
Refrain from charging excessive legal costs.
Act with honesty and candour in all dealings with courts and tribunals and otherwise discharge all duties owed to courts and tribunal.
Observe any undertaking given to a court or tribunal, the Legal Ombudsman, the Legal Practice Board, a Recognised Professional Association or another practitioner.
Act with honesty, fairness and courtesy in all dealings with other practitioners and firms in a manner conducive to advancing the public interest.
Conduct all dealings with other members of the community and the affairs of clients that effect the interests of others with honesty, fairness and courtesy in a manner conducive to advancing the public interest.
