It is an accepted principle of natural justice that a person should not be a judge in his or her own cause. In common law, this principle has been derived from the Latin maxim—nemo debet esse judex in propria sua causa. A reasonable permutation of this principle is that no Judge should adjudicate a dispute which he or she has dealt with in any capacity, other than a purely judicial one. The failure to adhere to this principle creates an apprehension of bias on the part of the said Judge.
