Everyone makes mistakes sometimes, even lawyers. A mistake could be caused by lack of knowldge, or bad judgement. “Mistake is not intentional – the lawyers decision to act or not may be intentional, but the poor outcome is unintentional,” says Catherine Gage O’Grady from the University of Arizona’s James E. Rogers College of Law, in a recent research paper called A Behavioural approach to Lawyer Mistake and Apology.
