I did a bit of law when I was in school, and recently, I recalled a unique feature of the law system regarding the way the names of judges were written, especially those with the title of Justice. Using an example:
Like other common law jurisdictions, when referred to in court judgments as Surname J. Judges in the New South Wales Court of Appeal are referred to as Justices of the Appeal (abbreviated Surname JA).
...(New Zealand) The "Mr" of the title "Mr Justice" was dropped on the appointment of Cartwright J to the High Court. In Court, all judges are addressed as "Your Honour", or "Sir/Madam".
So, if I was to write about a case, and the Judge had made a decision, and I wanted to relate that decision, I would write something like:
In view of the evidence and circumstances, it was ruled by Kritwal J. that there was not sufficient evidence to convict the accused, and hence, the accused was acquitted.
Why do the legal people do this? And what is the origin of this practice?
