A Hong Kong court has ordered an individual investor who unsuccessfully represented himself in a suit against DBS Bank over losses from so-called minibonds to pay the bank’s legal costs, with interest.

In a costs decision issued Monday against plaintiff Shum Kin Yee, Hong Kong District Court Judge Simon Leung said he “would not be surprised if the legal costs incurred by the Bank might have matched, if not exceeded, the amount of claim even before trial.”
