STANDARD OF PROOF:
APPLIED BY THE COURT OF ARBTIRATION
FOR SPORT IN DRUG-RELATED CASES
DR CHRIS DAVIES*
Abstract
The common law has developed many principles in
relation to evidence, including two standards of proof, one
for criminal cases and one for civil matters. Many sporting
disputes are now settled by the Court of Arbitration for
Sport (CAS) and it utilises a third standard of proof, namely
'comfortable satisfaction', which is defined as lying in
between the criminal 'beyond reasonable doubt' and the
civil 'balance of probabilities'. Despite stating that it is not
bound by the rules of evidence, an examination of CAS
drug cases indicates that it operates in a similar way to
common law courts in regards to how it uses the evidence
presented to it.
I INTRODUCTION
The common law has developed numerous principles in relation to
evidence, including who should bear the onus of proof, and to what
standard. Principles have developed in regard to the use of direct
and circumstantial evidence. The doctrine of presumptions has also
developed in order to allow certain evidence to be accepted, unless
rebutted. However, within the sporting context, it is the Court of
Arbitration for Sport ('CAS') which is now the usual final avenue of
appeal in many sport disputes. It is a non-judicial, international body
which has made it clear that it does not have to follow the rules of
evidence.' For example, in regards to standard of proof, what has
become accepted under the rules of CAS and other sporting bodies, has
