We have two types of complaints. Some complaints deal with overly long response times. Others are related to requests that were responded to, but with redacted documents.
I would say that the intent you're speaking of or the lack of desire to provide all the requested information is more evidenced by the redaction of documents. When we get complaints of this nature, we compare the original document to the redacted one. We see what information is contained in both documents. We have access to everything.
We sometimes have to ask why some of the information was redacted when it wasn't just one month earlier. Is there an intent to hide information or did the institution use the exemption differently?
What I've observed is that the exemptions provided in the act are used more readily than the discretionary power. For example, the institution could wonder if it has to use this power to give people more information so that they understand what measures are implemented and how decisions are made.
