ISLG has five principal Research Tools to facilitate its Multifaceted Research approach. Each tool allows you to conduct your research with Pinpoint Accuracy.

1.     The Subject Navigator
The Subject Navigator is a fast and efficient way to narrow down and isolate issues relevant to your research, which can then be supplemented through use of our other Research Tools.

It is a vast electronic directory of investment treaty arbitral law which lays out subjects in branches and sub-branches of ever increasing detail. You can survey complex subjects (e.g., fair and equitable treatment) and drill down into the nuances of each issue and sub-issue, ultimately arriving at the specific passage or footnote of a case where that issue or sub-issue is discussed.

The Subject Navigator makes no attempt to judge a particular finding as right or wrong. Where a tribunal or arbitrator expresses doubt or criticism of a prior decision or award, this is noted. It is left to you to decide what significance should be attached to a particular finding.

2.     The Article Citator
The Article Citator enables you to instantly see how specific legal instruments relevant to international investment law have been interpreted by tribunals. By selecting an instrument, or a particular provision within that instrument, you are taken directly to the paragraph(s) or footnote(s) where that instrument/provision has been applied or interpreted by tribunals. Using this tool, you will be able to capture references that are difficult to find using a full-text search.

3.     The Jurisprudence Citator
The Jurisprudence Citator enables you to instantly see how specific decisions have been treated by subsequent investment treaty tribunals. This includes both investment and non-investment treaty decisions (e.g., International Court of Justice judgments). Two types of tools are available: the first provides you with the cases where tribunals refer to a decision generally; the second provides you with pinpoint references to specific paragraph(s), footnote(s) or passage(s) of a particular decision.

4.     Terms & Phrases
Terms & Phrases enables you to look for the meaning of terms and phrases that have been defined in treaties and rules or by arbitration tribunals. This tool is integrated with the other Research Tools, allowing you to easily navigate throughout the database.

5.     Full-text Search
The Full-text Search enables you to tailor your legal research and control your findings while providing you with the flexibility of a full-text search. Standard functionality combined with the ability to filter results by specific types of decisions (e.g., decisions on interim measures of protection), by country (i.e., all cases involving a particular respondent State(s)), by applicable treaty or arbitration rules or by arbitrator(s). This tool is also integrated with our other Research Tools, enabling you to complete your research after beginning with a more targeted approach.
