I just called the CPS deputy director, because he had promised to call me by yesterday to tell me my rights to appeal. He now says that he is washing his hands of the case, and had turned it over to the Director of CPS. He said that she will call me this week. He implied that there would be a big pile of forms to fill out if I really wanted to appeal.
There must be something unusual about my case that it merits the attention of the CPS director. My guess is that it is unusual because CPS is reporting abuse without any example of abuse. But I don't know. I will look forward to her call.
