At the meeting of the IISL Board of Directors held at Brighton, United Kingdom, in October 1987, the Board decided to create a standing committee of the Institute to prepare and submit at each annual Colloquium a report on the status of agreements relating to activities in outer space.
Institute members who can contribute substantively to the work of the committee are invited to serve on it. Membership is open to any interested IISL member. The committee members help collect, review and verify data concerning selected space agreements. Agreements of general global applicability or regional applicability are selected for reporting. Bilateral agreements are not included in the report. In general, the agreements included in these reports, and their status, are believed to be valid as of the dates indicated in the respective reports.
