"22. I should add that the most up to date summary of the law in relation to joint tortfeasance is to be found in the judgment of the Supreme Court inSea Shepherd UK v Fish & Fish Ltd[2015] UKSC 10 ;[2015] AC 1229 . I attempted a very short summary of the key criteria for joint tortfeasance identified by Lord Sumption inSea Shepherdin my judgment inVertical Leisure Ltd v Poleplus Ltd[2015] EWHC 841 (IPEC) , where I said this at paragraph 66: "
"19. As I said, inGrenade, where an allegation of joint tortfeasance is raised against an individual who is the sole shareholder and director of the company, in effect there is evidential burden on the person to explain why the court should not assume that he or she personally carried out the acts of the company which are complained of in the proceedings. In this instance, I had the opportunity to ask Mr Grainger whether any other person took any significant role in the running of the first to third defendants. He said very fairly that while he took advice, including professional advice, from others about the running of the companies, the buck stopped with him, and that he took all significant decisions. That being so, it seems to me that Mr Grainger is liable as a joint tortfeasor."
“119 In my judgment, as a sole director and sole shareholder with self-professedresponsibility for the business, the shift in evidential burden set out in Grenade is engaged here. The facts of this case differ from those in Grenade and in Zockoll. In Grenade, Mr Chawla, the second defendant, was said to be a "one-man company". It does not appear from that judgment that the corporate defendant had any employees. The position is less clear from the report of the decision in Zockoll, but what is clear from Zockoll is that "the buck stopped with [the fourth defendant], and that he took all significant decisions". In my judgment, that finding is at one with the present facts, and Mr Steele's own evidence.”
