Not one to defend the partnerships but the guidance from the government when FoI was approaching was pretty vague. The whole process seemed to be based on 'minimal manual' with legal precedents to guide the development of how organisations should treat requests veering into the many grey 'you decide what to disclose -but justify it well' sections. Its a complicated area.
The partnership may well have been a bit guarded (they would be wouldn't they) but without legal precedent, one person's interpretation of the act can be completely different to another's.
Glad a partnership was the first LA to cop some flak though.
