'There is, of course, a balancing exercise ... to be taken into account in that regard. There is considerable delay by the defendant in bringing the application to join the third parties. That delay has not been, in my view, satisfactorily explained. The defendant points to delay by the plaintiff, but while there has been some delay, the proceedings nevertheless have been on foot for some considerable time.
In addition, regard must be had to whether the issuing of the third party proceedings would unduly complicate the hearing of this action. There is, it can be said, likely, given the matters raised in the defence, to be some evidence as to Mr So's involvement, but it will of course not be of the extent and nature that will arise if third party proceedings are permitted. The same applies in relation to the issue of the joinder of the proposed first third party.
In my view, the joinder of those parties is likely to add considerably to the complexity of the issues to be determined at trial, and the length and cost of proceedings.
It is open to the defendant to bring separate proceedings against the proposed third parties. It is always a factor to be taken into account that duplication of proceedings is to be avoided, but in my view, the issues that arise in the proposed third party proceedings are of a distinct nature from those raised in the defence, and not likely to be central in the current proceedings.
The proceedings are presently ready for hearing save for this application, and it is not in the interests of justice that there be yet further delay until the present action can be finalised.
Accordingly, I do not consider that it is appropriate to grant the application, and I refuse to do so in the exercise of my discretion.'
