Samantha Robb
Senior Associate | Ocean Litigation
“Protecting the Ocean is vital not only for the survival of humanity, but also for the inherent value of marine ecosystems themselves. Through strategic litigation, we can hold accountable those who threaten the Ocean’s health, and safeguard vulnerable ecosystems and the rights of all living species, present and future.”

Samantha Robb’s work focuses on high-impact international litigation aimed at developing, strengthening, and enforcing marine environmental protection laws and commitments, with a particular emphasis on marine protection in the context of deep seabed mining. A qualified lawyer and trained public interest litigator, Samantha spent six years at one of South Africa’s leading law firms (Webber Wentzel), with a focus on representing communities in cases that spanned Human Rights, environmental justice, and constitutional law. She holds an LLM in Public International Law, specialising in Oceans, the Environment, and Sustainability (cum laude) from Utrecht University in the Netherlands. Her LLM thesis focused on the legality of the call for a moratorium on deep seabed mining, a subject that continues to shape her work today.
With extensive expertise in both International Law of the Sea and Human Rights, Samantha brings a unique perspective to legal issues at the intersection of Ocean protection and social justice, ensuring that environmental protection efforts also seek to uphold fundamental human rights and vice versa.
Samantha’s current focus areas include deep seabed mining, marine protection through area-based management tools, the Human Right to a Clean, Healthy and Sustainable Environment and how it relates to Ocean issues, the BBNJ Agreement, bottom trawling, and Whaling. She brings deep experience working at the intersection of science, law, and policy - a crucial skill for navigating the complex currents of ocean governance.
Her work is grounded in accountability, ecosystem protection, and a vision for legal tools that defend both people and the planet.
