“In my judgment the Upper Tribunal was right not to attempt to provide any comprehensive or exhaustive definition. It would be better to allow CP v The Information Commissioner[2016] UKUT 0427 (AAC) GIA/252/2015 8 the meaning of the phrase to be winnowed out in cases that arise. However, for my own part, in the context of FOIA, I consider that the emphasis should be on an objective standard and that the starting point is that vexatiousness primarily involves making a request which has no reasonable foundation, that is, no reasonable foundation for thinking that the information sought would be of value to the requester or to the public or any section of the public. Parliament has chosen a strong word which therefore means that the hurdle of satisfying it is a high one, and that is consistent with the constitutional nature of the right. The decision maker should consider all the relevant circumstances in order to reach a balanced conclusion as to whether a request is vexatious. If it happens that a relevant motive can be discerned with a sufficient degree of assurance, it may be evidence from which vexatiousness can be inferred. If a requester pursues his rights against an authority out of vengeance for some other decision of its, it may be said that his actions were improperly motivated but it may also be that his request was without any reasonable foundation. But this could not be said, however vengeful the requester, if the request was aimed at the disclosure of important information which ought to be made publicly available…”
“In addition to the above steps, Mr Parker also lodged FOIA requests with the HRA from time to time, all touching on the broad issue of HRA’s processes in respect of committee appointments and complaints in respect of them. These led to at least one instance of a complaint to the Information Commissioner and an appeal from his determination to this Tribunal and from there to the Upper Tribunal.”
