"This suggests that [the Appellant's] persecutorybeliefs persist, even when presented with evidence that could contradict them. Delusions are firmly held beliefs that persist despite evidence disproving or challenging them. For the individual experiencing them, these beliefs feel entirely real and are often resistant to change, regardless of efforts to challenge or disprove them. Based on the information reviewed, it is reasonable to consider, on the balance of probabilities, that [the Appellant's] beliefs may have reached the threshold of delusional intensity."
"In my opinion, on balance of probabilities, the information available suggests the possibility of a delusional disorder."
"due to her firmly held beliefs which persist despite evidence against these, on balance, her ability to use and weigh up information relevant to the court proceedings is likely to be affected as a result"
‘Typically, a psychiatric assessment would entail a thorough evaluation designed to identify any underlying mental health conditions and understand the individual’s difficulties. This process involves gathering information about the person’s presenting symptoms, including their onset, duration and impact on daily life. A review of the individual’s medical, personal, and social history is conducted, with particular attention to factors such as substance use, trauma, family background, and occupational history. The assessment also includes a mental state examination, which evaluates aspects such as appearance, behaviour, speech, mood, thought processes, and cognitive function. Standard diagnostic tools may be used, and additional information may be sought from medical records, family members, or other professionals to inform the assessment.’
"Capacity is both issue-specific and time-specific. A person may have capacity in respect of certain matters but not in relation to other matters. Equally, a person may have capacity at one time and not at another. The question is whether at the date on which the court is considering the question the person lacks capacity in question."
"For the purposes of …CPR 21 - the test to be applied, as it seems to me, is whether the party to legal proceedings is capable of understanding, with the assistance of such proper explanation from legal advisers and experts in other disciplines as the case may require, the issues on which his consent or decision is likely to be necessary in the course of those proceedings. If he has capacity to understand that which he needs to understand in order to pursue or defend a claim, I can see no reason why the law – whether substantive or procedural – should require the interposition of a next friend or guardian ad litem (or, as such a person is now described in the Civil Procedure Rules, a litigation friend)." 41. An example of the application of the MCA 2005 principles to a decision whether a person lacks capacity to conduct litigation is the judgment of Burnett J (as he then was) in V v R[2011] EWHC 822 (QB) . Having set out the statutory provisions, the judge said (at paragraph 10): "
“24. It is necessary to reiterate that the test remains that in Masterman-Lister v Brutton & Co; Masterman-Lister v Jewell[2002] EWCA Civ 1889 ,[2003] 1 WLR 1511 , (2002) 73 BMLR 1, endorsed in Dunhill v Burgin (Nos 1 and 2)[2014] UKSC 18 ,[2014] 1 WLR 933 , [2014] COPLR 199, (2014) 137 BMLR 1. The essence of those judgments is to confirm, unambiguously, that capacity to litigate is addressed by asking whether a party to proceedings is capable of instructing a legal adviser 'with sufficient clarity to enable P to understand the problem and to advise her appropriately' and can 'understand and make decisions based upon, or otherwise give effect to, such advice as she may receive'. It follows that the issue of litigation will always fall to be determined in the context of the particular proceedings: Sheffield City Council v E and Another[2004] EWHC 2808 (Fam) ,[2005] Fam 326 ,[2005] 2 WLR 953 , sub nom Re E (An Alleged Patient); Sheffield City Council v E and S[2005] 1 FLR 965 . None of this requires P to instruct his advisers in a particular way. Like any other litigant, in any sphere of law, he may instruct his lawyers in a way which might, objectively assessed, be regarded as contrary to the weight of the evidence.”
