This is from the International CC website.
<<<There is also great procedural flexibility within the context of a given arbitration. For example, the parties can choose to have a slow and thorough or a fast and economical arbitration. For obvious reasons, speed, efficiency and costs are usually considered important. Where appropriate procedures are put in place, arbitration can be faster and less expensive than litigation, especially considering that there is generally no appeal from international arbitral awards.>>>
I wonder if that no appeal version is applicable with Huaweii and Interdigital.
