Citation percolation

The citation discussion has percolated nicely, with lots of good comments. Before I chime in with my take, I'd like to ask a question:

In judicial opinions, the citation form is almost always wrong. Why?

Because judges often have their own idiosyncratic preferences that do not match the current Bluebook?

Because judges and their clerks are only human and are no better than the practicing bar at citation form?

Because the publishers of judicial opinions alter the form before we see it?

Why? Send your answers to me or post a comment.
