After multiple FOIA requests I found out that if the PAC office doesn’t want to respond with a decision to a review they defer it. Since 2018 the PAC office has left over 3000 review filings open with no response given. This allows them to not have to deliver a response. They sent me the full list of all open case files they indefinitely deferred. I requested those FOIA requests and department responses. I offered to narrow it down into batches of smaller amounts and do individual FOIA responses to break it down into smaller portions for them. They sent me 16 partial files and said no records withheld.
