Evidence in International Arbitration: Criteria for Admission

(extract from Konstantin Pilkov. Evidence in International Arbitration: Criteria for Admission and Evaluation. Arbitration. – 2014. – Vol. 80. – Issue 2 2014)

Arbitration rules give broad authority to arbitrators regarding the consideration of evidence.[1] They usually do not set any formal procedure of admission and evaluation of evidence and say little if anything about the criteria for such admission and evaluation. The UNCITRAL Arbitration Rules (as revised in 2010) art.27(4) provide that once a party offers evidence to prove the facts it relies on, the tribunal is required to “determine the admissibility, relevance, materiality, and weight of the evidence offered”.
