“in some cases, the burden of complying with the request will be sufficient, in itself, to justify characterising the request as vexatious, and such a conclusion is not precluded if there is a clear public interest in the information requested. Rather, the public interest in the subject matter of a request is a consideration that itself needs to be balanced against the resource implications of the request, and any other relevant factors, in a holistic determination of whether a request is vexatious.” i. The Commissioner contends that this is a case where the burden of compliance in itself justifies characterising the Request as vexatious. j. In any event, the burden of compliance outweighs the purpose and value of the Request on the facts of this case. This is because (i) compliance would impose a real and significant burden upon the NHS Trust which would distract it from its other necessary functions in the context of significant resources pressures in the NHS, (ii) a reasonable person would conclude that the burden imposed on the Trust by the Request would be unwarranted and disproportionate to is value, especially when considered in the context and history of the request. k. From the context and history of the request, the Commissioner considers that compliance is likely to lead to further communication and requests from the Appellant with consequential burden on the Trust and its staff. Dransfield at [39] makes clear that that “the number, breadth, pattern and duration of previous requests may be a telling factor”
