Usually when there is media attention attached to information released to the public (press, SAR, freedom of information request, parliamentary question etc) the final response is tediously prepared. As in large email chains with department directors, deputy directors, ministers, policy senior leaders, legal teams etc signing off the data & narrative.
If they can decline to release, they will. Hence why Fife’s initial response re legal costs.
However this level of sign off wouldn’t be common for unremarkable SARs by a member of the public, so there was likely little oversight of what was being sent.
Reading between the lines, the fact that damning document was sent to a member of the public, indicates at the very least that the data team was worried about it. Was probably an internal shitshow before the document was wrongly shared, data team very much monitoring it and talking about it.
