That's what puzzles me the most. The tribunal clearly recognizes your effort was legitimate, well-documented and in good faith while making a pretty good case that QMUL took the opposite approach. Their arguments are barely a notch down from the earlier debunked claims of borderline psychopaths. It mostly seems to boil down to burden, but only theirs, and there is a lot of speculation into justifying it, especially an assumed futility.
It does bolster once more the case that their claims of harassment are exaggerated, which the tribunal notes and yet somehow can't really bring itself to take into account as lowering the credibility of obvious bad faith claims. It's an nth iteration of crying wolf, just not the last one yet.
Classic Picard: It is possible to commit no mistakes and still lose. That is not a weakness. That is life.
The way I see it is this: they recognize there has been a burden on QMUL (even if some of it has been self-inflicted) and they accept that there has been a lot of requests (and I have made a few of them), and as they point out, I have pretty much had the second part of my request handed to me. The question then is: is there enough value in my request to add to the burden. And they think in all the circumstances probably not. They have then, overturned all the nasty stuff, rapped QMUL and the IC on the knuckles and then told me not to push my luck and leave it at that. I can live with that.
Someone who knows about this stuff has described the decision as follows:
'At the end of the day the Tribunal didn’t believe that the requested data would be reliable enough to justify the effort to produce them. But they were obviously impressed with the way you made your case - and dismayed by the way the ICO made its.
I think you should be proud of this decision...'
