There are also a number of procedural and formality challenges that a party might face when seeking to enforce an award. One example of a common area of procedural dispute is whether (as a matter of domestic law) a party has been adequately served with all necessary documents. In England, the English Civil Procedure Rules (CPR) prescribe which documents should be served and how. There are also specific rules in respect of service on a State – these are found in both the CPR and the State Immunity Act. Added to that, when serving an order on a foreign State, it will frequently involve serving the State outside of the jurisdiction of the enforcing courts. In England, that means certain formalities must be complied with (as set out in the CPR).
