The failure by an arbitrator to apply his or her mind to the material issues at hand will usually be an irregularity. However, before such irregularity will result in the setting aside of an arbitration award, it must reveal a misconception of the true enquiry or result in an unreasonable outcome. What are the requirements to be met for an arbitration award to be set aside under the above circumstances?
The locus classicus remains Head of Department of Education v Mofokeng and Others (2014) 25 SALLR 82 (LAC); (2015) 36 ILJ 2802 (LAC);  1 BLLR 50 (LAC), where the labour appeal court said the following:
‘ The failure by an arbitrator to apply his or her mind to issues which are material to the determination of a case will usually be an irregularity. However, the Supreme Court of Appeal (“the SCA”) in Herholdt v Nedbank Ltd and the labour court in Goldfields Mining South Africa (Pty) Ltd (Kloof Gold Mine) v CCMA and others have held that before such an irregularity will result in the setting aside of the award, it must in addition reveal a misconception of the true enquiry or result in an unreasonable outcome…
 …Mere errors of fact or law may not be enough to vitiate the award. Something more is required. To repeat: flaws in the reasoning of the arbitrator, evidenced in the failure to apply the mind, reliance on irrelevant considerations or the ignoring of material factors etc. must be assessed with the purpose of establishing whether the arbitrator has undertaken the wrong enquiry, undertaken the enquiry in the wrong manner or arrived at an unreasonable result. Lapses in lawfulness, latent or patent irregularities and instances of dialectical unreasonableness should be of such an order (singularly or cumulatively) as to result in a misconceived inquiry or a decision which no reasonable decision-maker could reach on all the material that was before him or her.
 Irregularities or errors in relation to the facts or issues, therefore, may or may not produce an unreasonable outcome or provide a compelling indication that the arbitrator misconceived the inquiry. In the final analysis, it will depend on the materiality of the error or irregularity and its relation to the result. Whether the irregularity or error is material must be assessed and determined with reference to the distorting effect it may or may not have had upon the arbitrator’s conception of the inquiry, the delimitation of the issues to be determined and the ultimate outcome. If but for an error or irregularity a different outcome would have resulted, it will ex hypothesi be material to the determination of the dispute. A material error of this order would point to at least a prima facie unreasonable result. The reviewing judge must then have regard to the general nature of the decision in issue; the range of relevant factors informing the decision; the nature of the competing interests impacted upon by the decision; and then ask whether a reasonable equilibrium has been struck in accordance with the objects of the LRA. Provided the right question was asked and answered by the arbitrator, a wrong answer will not necessarily be unreasonable. By the same token, if an irregularity or error material to the determination of the dispute may constitute a misconception of the nature of the enquiry so as to lead to no fair trial of the issues, with the result that the award may be set aside on that ground alone. The arbitrator however must be shown to have diverted from the correct path in the conduct of the arbitration and as a result failed to address the question raised for determination.’
In Minister of Police v M and Others (2016) 27 SALLR 53 (LC); (2017) 38 ILJ 402 (LC), the labour court identified the content of hearsay evidence of a special type affording greater weight than simple hearsay. What is the approach adopted by the labour court in such case as to the transcript of an internal enquiry admitted as hearsay evidence in terms of s3(1)(c) of the Law of Evidence Amendment Act? Subsequent to such judgment, the labour court, in Department of Home Affairs v General Public Service Sector Bargaining Council and Others (2019) 30 SALLR 172 (LC); (2019) 40 ILJ 2544 (LC), had the opportunity to apply the approach adopted in the aforesaid judgment to the specific facts of this matter. In this subsequent judgment, how did the labour court identify such transcript of an internal enquiry as not constituting hearsay of a special type (as required in Minister of Police v M (supra))?
According to the constitutional court, when a referral is made to the CCMA or a bargaining council concerning a dismissal, is it a requirement that the reason for the dismissal (i.e. misconduct, incapacity poor work performance, etc) is also identified in order for such CCMA or bargaining council to require the requisite jurisdiction?
What are the principles governing hearsay evidence as contained in the Law of Evidence Amendment Act 45 of 1998 and applied by the labour court in, inter alia, Swiss South Africa (Pty) Ltd v Louw NO  4 BLLR 373 (LC) and NUMSA v SA Metal & Engineering Industries Bargaining Council and Others (2014) 25 SALLR 4 (LC)?
