R (Adegun) v SSHD [2019] EWHC 22 (Admin)
"There are two bases of challenge to Mr Adegun's detention which, in broad outline, are as follows. ... There is first an issue, which I shall call the "rule 34 issue", as to whether Mr Adegun declined a medical examination pursuant to rule 34 of the Detention Centre Rules when he was taken into detention. ... The second issue I shall call the "paragraph 55.10 issue". It arises because there is evidence, not disputed by the Secretary of State, that Mr Adegun was suffering from a mental health condition which was not recognised by the Home Office until some time after his admission into detention and was not treated with medication until 19 January 2016. ... I therefore propose to award nominal damages in respect of the early period of Mr Adegun's detention and substantial damages in respect of 40 days' detention."
