"In the circumstances, given that you did need to come here today, given the ambiguity in the undertakings and the urgent nature of the application and the fact that not even one ambiguous undertaking was given until late in the day after your brief fee had become incurred for this hearing, it seems to me that the costs are reasonable, and I will summarily assess in the amount claimed."
"Where the purpose of an interim injunction is to 'hold the ring' until trial, the cost of the application will usually be reserved (Richardson v Desquenne et Giral UK Ltd [1999] CPLR 744;[2001] FSR1 , Picnic at Ascot v Kalus Derigs[2001] FSR2 ). The Desquenne principle overrides the usual rule that the unsuccessful party bears the costs because, in a case where the injunction is granted on the balance of convenience, at that stage there is no winner or loser (Wingfield Digby v Melford Capital Partners (Holdings) LLP[2020] EWCA Civ 1647 ). Where however the injunction is granted not merely on the balance of convenience, the issues considered on the application will not be revisited in the substantive proceedings, if there is a winner and a loser on those issues, the loser should pay the winner's costs (Koza Ltd v Koza Altin Isletmeleri AS[2020] EWCA Civ 1263 ."
