From the weekend L.A. Times, by Harriet Ryan:

In a statement attached to the newly opened file, Los Angeles County Superior Court Judge Maureen Duffy-Lewis said a series of missteps, each committed "inadvertently," led to the concealment of every part of the case -- including its very existence. She wrote that she sealed the entire suit when she meant to seal only the exhibits, filed all case documents in a sealed envelope when only a few belonged there and then forgot to revisit the issue after the case was settled.

Otherwise, it was all perfect.
