Recovery of high interest rates

In F&C Alternative Investments (Holdings) Ltd v Francois Barthelemy & Anthony Culligan, parties to a complex litigation had been compelled to take out loans at a high rate of interest to pay for their legal costs, and where their opponent had acted in such a way as to attract an order for costs on the indemnity basis, it was appropriate that they should be paid interest on costs at the actual rate that they had been forced to incur.

Will this have any future role in cases where third party funders are involved? Will be a something to keep an eye in future.
