Withers International Investment Law Prize Winner

"Thanks to the Withers International Investment Law prize, I have just completed a month-long internship with Withers' international arbitration team. I am hugely grateful to Dr Emilia Onyema and Mr Hussein Haeri for organising this fantastic opportunity. The firm has been incredibly supportive in accommodating my internship during the COVID-19 pandemic and I am thrilled to say that the arbitration team has remained extremely busy. Despite the huge caseload and having to work from home, the team has been incredibly enthusiastic and it was a pleasure to work with everyone. I was lucky enough to assist on several investor-state matters looking at various issues including enforcement, jurisdiction and procedure, as well as participating in a public international law tutorial and assisting with various business development projects. There was never a dull moment and I would highly recommend all future students to make the most out of the international investment law class so that they might also get the opportunity to work on some dynamic cases with the charming team at Withers" - Amelia Kelly
