"The burden of proving a failure by the Applicant to mitigate loss of earnings is on the [Respondent] and it is for the [Respondent] to provide the Tribunal with evidence on which to base a finding of a failure to mitigate or a quantification of any consequent reduction in the value of the claim and not for the industrial tribunal to remedy gaps in the evidence on the basis of its own knowledge and experience."
"If a Tribunal is to be invited to consider whether or not there has been a failure to mitigate or if there has been such a failure, the quantification of any reduction in the value of the claim, it must be provided with the evidence with which to perform its task, either arising from cross-examination or from evidence called by the [Respondent]."
