I've never been directly involved in an Ombudsman complaint, and I'm long out of touch with anything Parliamentary but - my impression is that MPs take the Ombudsman process pretty seriously and don't like being involved in low chance of success cases and/or cases that are other than unequivocally evident of injustice (Knight on white horse syndrome). Free doesn't mean there is no test of validity - indeed the first hurdle is whether the complaints procedure of the contentious organisation has been exhausted: follow the "can we look into your complaint" arrows here:
https://www.ombudsman.org.uk/
I'm dubious about cage rattling in my (limited) experience, rather than promoting positive action it produces retreat to the bunker responses and an unwillingness to engage positively. In this case we do not know that Cochrane has acted outside the Law or acted contrary Charity Commission guidance, and there's no substantive evidence of maladministration by the CC. We can see why it both organisations are 'in the wrong' but that doesn't mean that they are wrong in Law or in regulation - that is a case to be made, and as far as I can see that needs significant work and expert advice. Part of that work is following the processes and building evidence along the way.
Cross posted but I think the above still stands
I really think this needs a clear view of the process. Although a complaint to the Ombudsman is not contingent on Caroline's engagement with the CC, in practical terms any complaint to the Ombudsman must have exhausted the complaints procedure of the contended organisation - here the CC, so if Caroline's complaint is not referenced a whole new complaint process with the CC will have to be started in another name, at which point the CC will reference a) it's already position (as put to Caroline) b) the need for any complaint to be put first to Cochrane - the new named complainant is then drawn back to Cochrane who will than refer to a) the Bastian review b) the principles that it is following in Caroline's complaint.
And if Caroline's complaint to the CC is referenced then the Ombudsman will merely test the CC's position which would lead back to Cochrane which is currently (seemingly) taking Caroline's complaint seriously and so 'no case'.
As I said above it's all about process - the CC has processes and it requires processes to be developed and followed by Charities, the CC will only involve itself where processes in a Charity are demonstrably failing (fraud, reputational damage etc) AND the Ombudsman will only find against the CC where its processes have demonstrably failed (maladministration). Circles of Hell etc.
So my conclusion is that a stepped approach, frustrating as it is, is the only way forward which is: Cochrane complaint process >success| or failure then> CC complaint process >success| or failure then> Parliamentary Ombudsman.
