Why our clients continue to trust ISLG

  • “ISLG is a very powerful and useful tool. It is a cost-effective research tool that is a benefit to our practice. I would recommend it to any lawyer practicing in international arbitration. It is not a plus. It is a must!”

    Alvaro Galindo
    International Counsel, Dechert LLP

  • “ISLG has made it easier and more cost-effective to research issues relating to investment treaty arbitration. The Jurisprudence Citator, which shows how specific decisions have been treated by subsequent investment treaty tribunals, is particularly useful.”

    Kristen Young
    Partner, White and Case LLP

  • “ISLG is your one-stop resource. No other database provides the researcher with so many effective and efficient ways to research and access treaties, rules of arbitration, decisions and awards, and other related documents.”
