The binding legal principles established are: (1) A corporate opportunity is one which the company was actively pursuing or which falls within the company's existing or prospective business activities - the inquiry requires examination of all relevant circumstances to determine whether exploitation by a director creates a conflict between personal interests and duties owed to the company; (2) An opportunity that is the antithesis of what the company pursued (e.g., employment with a competitor rather than collaboration with that competitor) is not a corporate opportunity the director must exploit for the company; (3) A director who resigns is free to compete with the former employer and exploit opportunities that arise after resignation or of which the director was unaware before resignation, provided there are no contractual restraints; (4) During a notice period, a director may take preparatory steps for future employment or business (incorporating companies, securing premises) without breaching fiduciary duties, but may not engage in actual competitive trading; (5) The substance of a transaction, not its form or labelling, determines whether it constitutes a breach of fiduciary duty; (6) A director's expertise, experience and personal relationships developed during employment belong to the director, not the company; (7) Causation must be established for damages claims - the inquiry is whether the wrongful conduct caused loss to the company, not whether the competing entity made a profit.
