Dealing with an ethical conflict

  1. Gather the facts, the ethical issues and the principles involved.
  2. Check the organisation's internal procedures.
  3. Consider the alternatives and their consequences.
  4. Discuss with those charged with governance; take advice from the professional body or a lawyer.
  5. Decide, record the decision, and if necessary withdraw from the engagement.
