There are many other clear examples of courts which have a statistical bias towards certain decisions. A very good example is that of Texas, where the vast majority (about 75%) of patent lawsuits are filed because they very often rule in favour of the plaintiff. This is why patent trolls often file suits in Texas.
The reason for that bias might be more complicated (the view of the local community which will be selected for a jury might be influenced through various means -- but that's a secondary question to the primary point that there is a statistical bias regardless of the reason for it).
