"i) The court must consider whether the claimant has a 'realistic' as opposed to a 'fanciful' prospect of success ... ii) A 'realistic' claim is one that carries some degree of conviction. This means a claim that is more than merely arguable ... iii) In reaching its conclusion the court must not conduct a 'mini-trial ... iv) This does not mean that the court must take at face value and without analysis everything that a claimant says in his statements before the court. In some cases, it may be clear that there is no real substance in factual assertions made, particularly if contradicted by contemporaneous documents ... v) However, in reaching its conclusion the court must take into account not only the evidence actually placed before it on the application for summary judgment, but also the evidence that can reasonably be expected to be available at trial ... vi) Although a case may turn out at trial not to be really complicated, it does not follow that it should be decided without the fuller investigation into the facts at trial than is possible or permissible on summary judgment. Thus the court should hesitate about making a final decision without a trial, even where there is no obvious conflict of fact at the time of the application, where reasonable grounds exist for believing that a fuller investigation into the facts of the case would add to or alter the evidence available to a trial judge and so affect the outcome of the case ... vii) On the other hand it is not uncommon for an application under Part 24 to give rise to a short point of law or construction and, if the court is satisfied that it has before it all the evidence necessary for the proper determination of the question and that the parties have had an adequate opportunity to address it in argument, it should grasp the nettle and decide it. The reason is quite simple: if the respondent's case is bad in law, he will in truth have no real prospect of succeeding on his claim or successfully defending the claim against him, as the case may be. Similarly, if the applicant's case is bad in law, the sooner that is determined, the better. If it is possible to show by evidence that although material in the form of documents or oral evidence that would put the documents in another light is not currently before the court, such material is likely to exist and can be expected to be available at trial, it would be wrong to give summary judgment because there would be a real, as opposed to a fanciful, prospect of success. However, it is not enough simply to argue that the case should be allowed to go to trial because something may turn up which would have a bearing on the question of construction ..."
"In April to May 2013 the claimant transferred to the defendant the total sum of CHF325,000. This sum was paid by four separate bank transfers from the claimant's Swiss bank account with UBS ... to the defendant's Swiss bank account with UBS ... as follows: (1) CHF50,000 on29 April 2013 , (2) CHF100,000 on29 April 2013 , (3) CHF100,000 on29 April 2013 , (4) CHF75,000 on30 May 2013 , together referred to as the 'debt'."
"Mutaz Flor and I have been trying to get the numbers from the past, prior to December 2012, finalised. I would like you to take the lead on this matter so we can put an agreement between me and Flor to carve out the past 50/50 liabilities, then transfer the shares of the current structures. Flor, the only way to close in the matter is to simplify the process as below: (1) get the exact real revenue that Floreat Family Office generated from 2008 to 2012; (2) get the exact cost that the Floreat Family Office has spent; (3) the difference between revenue and costs as financed by third parties including me and you; (4) define the real investments that were made from funds allocated by me; (5) where the payments for Paradise and Paddle A(?) shareholding were paid from; (6) get the balance, then put an agreement between the two of us. To be clear, the period December 2012 until now, the liabilities would be divided per the new shareholding as all the funds are being counted as loans to the company. We need to put a deadline to this matter. I will set up a time in the diary for us to review progress on a weekly basis."
"The transfer of the debt to the defendant. 15. As far as the Otaibis were aware, Dr Treu had obtained a personal loan of approximately CHF250,000 from a Mr Mutschler which was due to be repaid on2 May 2013 . 16. On27 April 2013 Dr Treu asked Mutaz Otaibi to assist him in administering various payments from the bank account belonging to Floreat Trustees AG ('Trustees') which Mutaz Otaibi had access to. This included administering a payment from Trustees to Dr Treu, for Dr Treu to repay the loan to Mr Mutschler. Dr Treu was due to go on holiday on28 April 2013 and therefore Mutaz Otaibi agreed to assist. 17. On28 April 2013 Dr Treu informed Mutaz Otaibi that he had put in place a number of payments to be made into Trustees' account for onward payment. This included the transfer to be made from Trustees to Dr Treu in order for Dr Treu to repay the loan to Mr Mutschler. 18. On29 April 2013 Mutaz Otaibi discovered that CHF250,000 had been transferred into the defendant's bank account by Dr Treu from the claimant. Mutaz Otaibi believed this to have been an error as the transfer ought to have been to Trustees' account for onward payment to Dr Treu."
"19. In light of the mistaken payment into the defendant's bank account on30 April 2013 , Mutaz Otaibi asked Dr Treu for Mr Mutschler's account details. Mutaz Otaibi did not want the loan to be paid from the defendant's bank account and informed Dr Treu that the payment needed to be made from Trustees. Mutaz Otaibi asked Dr Treu to affect another transfer from the claimant to Trustees for onward transmission to Mr Mutschler. 20. Dr Treu did not affect the further transfer from the claimant to Trustees and as such, on the same date, Mutaz Otaibi transferred the CHF250,000 to Dr Treu's personal account for Dr Treu to administer the repayment to Mr Mutschler himself. For the avoidance of doubt, Mutaz Otaibi did not have access to the claimant's bank account. 21. In the circumstances, CHF250,000 has been repaid to Dr Treu."
"In the light of these observations, and having regard to the nature of principles underlying the right to restitution in the case of a mistaken payment and the defence of change of position, I do not think that dishonesty in the sense identified in Twinsectra Ltd v Yardley is the sole criterion of the right to invoke the defence of change of position. I do not think that it is desirable to attempt to define the limits of good faith; it is a broad concept, the definition of which, insofar as it is capable of definition at all, will have to be worked out through the cases. In my view it is capable of embracing a failure to act in a commercially acceptable way and sharp practice of a kind that falls short of outright dishonesty as well as dishonesty itself. The factors which will determine whether it is inequitable to allow the claimant to obtain restitution in a case of mistaken payment will vary from case to case, but where the payee has voluntarily parted with the money much is likely to depend on the circumstances in which he did so and the extent of his knowledge about how the payment came to be made. Where he knows that the payment he has received was made by mistake, the position is quite straightforward: he must return it. This applies as much to a banker who receives a payment for the account of his customer as to any other person ... Greater difficulty may arise, however, in cases where the payee has grounds for believing that the payment may have been made by mistake but cannot be sure. In such cases good faith may well dictate that an enquiry be made of the payer. The nature and extent of the enquiry called for will, of course, depend on the circumstances of the case, but I do not think that a person who has, or thinks he has, good reason to believe that the payment was made by mistake will often be found to have acted in good faith if he pays the money away without first making enquiries of the person from whom he received it."

"The effect of the document is either that the payment to the defendant was by the claimant on behalf of Trustees, or that it was intended to be by the claimant to Trustees for onward payment to the defendant."
