The UK Supreme Court has decided that a claim for negligence and breach of statutory duty against a Zambian mining company and its English parent can be heard by the English courts. The much anticipated decision has important ramifications for British multinationals whose subsidiaries and suppliers operate abroad, particularly in regions where there is a higher risk of adverse environmental and human rights impacts and claimants face practical barriers to accessing effective judicial remedies. It also is an important decision for potential claimants motivated to seek access to judicial remedies against multinational corporations in their home jurisdictions.
