The use of dispute resolution with a forum selection clause is widespread and continues to grow so that it is now commonplace to have such a clause inserted in an agreement with an international element. One of the salient issues related to such clauses or agreements is what the consequences are if a party avoids compliance. This article aims to provide an anatomy of this matter: first, how a dispute resolution agreement should be perceived, and what obligations it creates for each of the parties (herein termed performance obligations); and second, a taxonomy of the types of liability that may flow from such a breach, both financial (e.g., damages, costs allocation) and non-financial. The article analyses and draws examples from a variety of both common law and civil law jurisdictions to provide a comprehensive mapping of the topic.
