"If the claim and counterclaim raise the same issues it may well be a matter of chance which party is the claimant and which a counterclaiming defendant and in such a case it will not usually be just to make an order for security for costs in favour of the defendant, although the court must always have regard to the particular circumstances of the case." 22. The rationale for this principle is that the sanction for not complying with the security for costs order is that if security were ordered and not provided, the claim might well be dismissed (Commercial Court Guide, Appendix 10, para. 6; Dumrul v Standard Chartered Bank[2010] EWHC 2625 (Comm) ; [2010] 2 CLC 661, para. 19) but the same underlying factual issues would still be litigated in the trial of the counterclaim (BJ Crabtree (Insulations) Ltd v GPT Communication Systems Ltd(1990) 59 BLR 43 ; Dumrul v Standard Chartered Bank[2010] EWHC 2625 (Comm) ; [2010] 2 CLC 661, para. 18; Ardila Investments NV v ENRC NV[2015] EWHC 1667 (Comm) , para. 67; Abbotswood Shipping Corporation v Air Pacific Limited[2019] EWHC 1641 (Comm) , para. 29). 23. That said, the fact that there is a claim and counterclaim arising out of the same or substantially the same facts and matters does not, of itself, mean that the defendant must be denied security for costs (Jones v Environcom Ltd[2009] EWHC 16 (Comm) ; [2010] Lloyd's Rep IR 190, para. 17-27). For example, if it is established that the Defendant would not have advanced its counterclaim had the Claimant not instituted proceedings, that well may be a relevant consideration in granting security for costs (Autoweld Systems Ltd v Kito Enterprises LLC[2010] EWCA Civ 1469 , para. 58-60). If, however, both parties - the Claimant and the Defendant - were intending to advance a claim and it was only a matter of chance of who instituted proceedings first, the Court might in those circumstances refuse to order security for costs, or it might order that both parties should provide security for costs, assuming that it had jurisdiction to do so (The Silver Fir[1980] 1 Lloyd's Law Reports 371 ; Petromin SA v Secnav Marine Ltd[1995] 1 Lloyd's Law Rep 603 ). 24. Insofar as any unfairness arising from this state of affairs might exist, if such unfairness can be neutralised, that may sweep aside any concerns entertained by the Court in allowing the application for security for costs. Thus, in Dumrul v Standard Chartered Bank[2010] EWHC 2625 (Comm) ; [2010] 2 CLC 661, Hamblen, J said at para. 19: "
