The summonses to adduce expert evidence were dismissed because the applicants failed to demonstrate that the proposed expert opinions were relevant, necessary and probative to resolve the live legal and factual issues: the matters relied upon were either for the court to decide on the applicants' own evidence, amounted to legal submissions or comparisons with foreign practice which were neither necessary nor determinative under Hong Kong domestic law, and treaty-based claims are governed by the dualist principle and thus primarily questions of domestic law.
