The 2017 Lachs Moot problem has been published: http://www.iislweb.org/docs/2017problem.pdf

The case involves a dispute between Perovsk and Titan, historically peaceful neighbors on Earth, who find themselves in an emotionally charged conflict on the Moon involving lunar facilities, liability for damage, and space mining. Several novel aspects are involved including a withdrawal from the Outer Space Treaty and an agreement by the parties to permit the Court to decide one set of issues ex aequo et bono.
