No matter if it's arbitration or court or in the US or Europe (or Singapore?), I trust the adjudicating powers to follow the laws as written and intended and in absolutely now way take into account 'the present climate'.
Ensign can educate you guys better on how arbitration work and, imho, if arbitration goes against Haas but they still refuse to hand over the money, even a US court will tell Haas to obey. The whole idea about having a contract and signing up for disputes to be resolved by arbitration is that courts can be avoided. Firstly to get a swifter resolve and secondly because the arbiter has a more detailed knowledge of commercial law than a judge don't have, meaning a better chance of a fair result for both parties.
