Why our clients continue to trust ISLG

“The best online resource for investment treaty law.”

Judith Gill QC
Allen & Overy LLP

“ISLG is an unparalleled database database of primary materials in investor state law and is supported by a powerful search engine. It is useful to practitioners and academics alike and equally practical for new and seasoned users. The lack of secondary material and the focus on primary sources focuses the mind to what really matters. Even when I have conducted my own independent research I always double-check with the ISLG database.”

Marci Hoffman

“ISLG is a very powerful and useful tool. I would recommend it to any lawyer practicing in international arbitration. It is not a plus. It is a must!.”
