The security for costs order was quite substantial and will most likely rise as the case progresses, however it is interesting to understand the reasoning behind this kind of order and how it applies to this case. Definition below:

The general rule in costs jurisdiction is that "costs follow the event". In other words, the loser in legal proceedings must pay the legal costs of the successful party. Where a defendant has a reasonable apprehension that its legal costs will not be paid for by the plaintiff if the defendant is successful, the defendant can apply to the court for an order that the plaintiff provide security for costs. Furthermore, the amount that is ordered by the Judge is in direct correlation to the strength or weakness of the plaintiff's case brought herewith.The weaker the probability of the defendant prevailing, the higher the security order.
