It might be enlightening to ask when you could get a copy of the court transcripts. As an interested party you should be permitted to get a copy, though you may have to pay for it.
I don't know anything about proper procedure. During out court appearances the other people in the room represented the county DHS (Dept of Human Services - our foster care name) and the State DHS. They only spoke up if asked something directly or they saw a glaring problem.
I honestly think this system has been rigged against you from the start. The PO is downright EVIL, in my opinion. She has been pulling strings behind your back for a long time. GAL is not impressive either - she seems 2 faced.
I am so very sorry. Hugs.
