The UK Supreme Court on Friday allowed a group of 42,500 Nigerian farmers and fishermen to sue Royal Dutch Shell (RDS) in English courts after years of oil spills in the Niger Delta contaminated land and groundwater.

Senior judges said UK-domiciled Shell, one of the world’s biggest energy companies, did have a common law duty of care, in the latest case to test whether multinationals can be held to account for the acts of overseas subsidiaries.
