My practice as part of the firm’s Dispute Resolution Group focuses on international dispute settlement. In particular, I advise and represent States and private entities in matters pertaining to public international law, treaty-based dispute settlement and international human rights.
I have expertise on a wide range of public international law topics, including inter alia the law of treaties, the law on State responsibility, the law on State and diplomatic immunity, international investment law, the law of the sea and Business & Human Rights. I have experience of protecting foreign investments through international arbitration, advising individuals and companies on claims against governments and on the enforcement of awards against sovereign entities. I have equally assisted States defending against claims before international courts and tribunals and safeguarding sovereign and diplomatic immunities before national courts. I have represented corporate as well as sovereign clients in international arbitration and litigation and have appeared as an advocate before the International Court of Justice in The Hague. I also practice in human rights, advising in particular on Business and Human Rights regulatory and guidance frameworks, corporate ESG responsibilities and human rights due diligence.
I hold a Master of Laws in Public International Law and Procedural Law and a Doctor of Laws in Public International Law, both from Uppsala University.
Prior to joining Westerberg & Partners in 2020, I practiced for six years at the public international law firm Volterra Fietta in London, where I primarily worked on State-to-State disputes and high-profile investor-State arbitration cases. Notable representations in the public domain include acting for the United Arab Emirates in Qatar v. United Arab Emirates (International Court of Justice), acting for the Federal Republic of Nigeria in Nigeria v. Interocean (ICSID), acting for the Arab Republic of Egypt in Al Jazeera v. Egypt (ICSID) and acting for Owens-Illinois EG on annulment in OIEG v. Venezuela (ICSID). I also provided advice to a number of governments on public international law matters, including inter alia the legality of military intervention and the use of force, international humanitarian law, international human rights, reservations to treaties and State and diplomatic immunities. I furthermore advised private parties on investor claims and Business and Human Rights issues.
Before entering into practice, I taught public international law at Uppsala University, acted as a clerk and junior judge at a Swedish district court and conducted an internship with the International Criminal Court.
I regularly speak and publish on public international law issues in various venues.
