- Court of First Instance
- Case number
- HCIP64/2019
The court granted leave for all of the Plaintiff's proposed amendments and granted the Defendants leave to amend in the specified parts because the contested amendments were, in substance, particulars of existing causes of action or raised issues appropriately resolved at trial (including choice‑of‑law questions), there was no unacceptable unexplained delay or irremediable prejudice and any prejudice could be addressed by costs, and interlocutory resolution of complex foreign‑law issues would be inappropriate.
