The Anti-suit Injunction Conundrum: How We Got Here and How to Avoid It

An anti-suit injunction is an interim order issued by a court in one jurisdiction that prohibits a litigant from initiating or continuing parallel litigation in another jurisdiction. The practice of the anti-suit injunction is traced back to fifteenth century England, where royal courts issued writs of prohibition to stay parallel proceedings in the ecclesiastical courts or common law courts. Initially, the use of anti-suit injunctions was limited in England. By the nineteenth century, however, their use expanded to prevent litigation in other British colonies and eventually foreign countries.
