You practice as an attorney in Pretoria since 2005. Your client, Resolve IT (Pty) Ltd, a major software company, is the defendant in a patent infringement lawsuit in which the plaintiff seeks R50 million in damages. Your father is one of the Directors of Resolve IT.

One evening, while working through your file and the documents provided by your client, you discover a document that conclusively proves the plaintiff's case. During a previous court appearance in the matter, the court has ordered that each and every document relevant to the case must be disclosed to the opposing side and the court.

Disclosing the document will cost your client R50 million and deprive you of your most lucrative source of income. When you tell the advocate of your client about the document, she instructs you that under no circumstances whatsoever are you too disclose the document to the plaintiff.
