This Practice Note discusses a key consideration of relevance when dealing with forum non conveniens, namely the factors connecting the proceedings to a jurisdiction (the connecting factors). For guidance on: • the approach in cases in which the parties have agreed a jurisdiction clause, see Practice Note: Forum non conveniens—jurisdiction clauses and the strong reasons test • the principle of forum non conveniens, as well as situations when it may be relevant and its application, see Practice Notes: Forum non conveniens—principles, Forum non conveniens—challenging jurisdiction and Forum non conveniens—service out of the jurisdiction • the requirement for justice consideration when applying the principle of forum non conveniens, see Practice Note: Forum non conveniens—requirement for justice Determining the ‘most real and substantial connection’ When dealing with an application involving cross-border issues, the court will need to consider whether it is the proper and appropriate forum to hear the dispute or whether it should be heard by the courts in another jurisdiction. Due to the international nature of the claims, a number of factors may be relevant.
