The criminal justice system is administered by human beings, not computers. While the decision-making process for each actor is governed by defined core principles, there may be significant individual variation in their application.
Everyone brings a distinctive pattern of behaviour and way of thought to the exercise of their role. Each person has their peculiarities, preferences, strengths and weaknesses.
For the advocate, behavioural idiosyncrasies matter. Counsel must tailor their approach to take into account the human element when advocating on behalf of a client.
