“Applicants who obtain permission to amend are often ordered to pay the other parties’ costs of and caused by the application (Taylor v Burton[2014] EWCA Civ 21 ; and as to the meaning of “cost of and caused by”, seePractice Direction 44 , para.4.2 (44PD.4). However, parties ought to consent to amendments they cannot reasonably oppose because, if they do not, they may be penalised in costs. In La Chemise Lacoste SA v Sketchers USA Ltd[2006] EWHC 3642 (Ch) , C sought D’s consent to amendments to the particulars of claim; when D made half-hearted attempts to resist by making proposals to deal with the matter in another way. C successfully applied for permission to amend and was awarded the costs of the application against D.”
