I see that on my justice review profile but nowhere in any of the stickies or FAQ about it.. no ranked list.. what is this??

It is where you place on the Tribunal leaderboards. Only the top 1000 judges have a ranking.

Your justice rating determines the ranking. Currently there is no way to view the leaderboards though there are a few threads where people have posted their ranks.

I suggest you do your own rankings for whatever goals you like to set for yourself.

Example Mine:

128 confirmed pardons out of 801 cases... Pretty damn happy about that.
