The Commissioner's Decision
19 The Commissioner stated at D[20] to [27] (footnotes omitted):
[20] On 17 August 2017, Mr Mwango and Mr Crotty were both rostered to work the afternoon shift in the SOS Laboratory at the Tomogo WesTrac site (Laboratory). Mr Crotty commenced work at 12:00pm.
[21] At approximately 2:00pm, Mr Mwango walked into the Laboratory. Mr Crotty said to Mr Mwango that he was about to start working on coolant samples, to which Mr Mwango responded with words to the effect "I'm sorry mate, I wasn't supposed to be here today." Mr Mwango then sat down on a black swivel chair facing the Ion Chromatography (IC) computer and began to complete a 'Take 5', which is a safety related procedure at WesTrac.
[22] Mr Mwango had been attending training for two days prior to 17 August 2017 and had not worked in the Laboratory during that time.
[23] At approximately 2:30pm, Mr Crotty walked over to Mr Mwango who was still seated facing the Ion Chromatography (IC) computer. Mr Crotty stood to the right of Mr Mwango. Mr Crotty began to update Mr Mwango on what had occurred in the Laboratory during Mr Mwango's absence. Mr Crotty told Mr Mwango that the Laboratory had received a nitrate standard, against which some initial results were tested, and a recalibration was performed to produce more acceptable results. In telling Mr Mwango this, there is no dispute that Mr Crotty said the word "shit".
[24] According to Mr Crotty, he "specifically and purposefully" referred to the initial results as being "shit" as opposed to Mr Mwango personally or Mr Mwango's work.
[25] Mr Crotty gave evidence that after he said the word "shit", Mr Mwango became extremely angry and aggressive. Mr Crotty gave evidence that Mr Mwango was shaking, his eyes were bulging and wide, and his voice changed dramatically. Mr Crotty gave evidence that the conversation continued in words to the following effect:
Mr Mwango: "You are saying that everything I do here is shit."
Mr Crotty: "I was referring to the nitrate result. This is not a personal attack on you."
[26] Mr Crotty gave evidence that Mr Mwango then said "you better be Caref" in a raised and aggressive voice whilst shaking, bulging his eyes and pointing directly at him. Mr Crotty alleges that he then asked Mr Mwango what he meant and Mr Mwango responded by repeating the words "you better be Caref". Mr Crotty gave evidence that when [Mr] Mwango said "you better be Caref" he understood the words to mean "you better be careful" and that he felt physically threatened because of Mr Mwango's raised voice and body language.
[27] Mr Crotty gave evidence that Mr Mwango then shouted words to the effect of "you can expect payback 150 percent" whilst shaking and gesturing towards him with an outstretched hand. Mr Crotty gave evidence that at that point he formed the view that Mr Mwango was going to punch him, so he walked five or six metres away from Mr Mwango but remained in the Laboratory.
20 The Commissioner recorded the applicant's account of the incident and submissions at D[30] to [35] (footnotes omitted):
[30] Mr Mwango submits that Mr Crotty and Mr Lai colluded to fabricate their evidence in relation to the 17 August 2017 incident.
[31] According to Mr Mwango, Mr Crotty said the word "shit" in reference to results that Mr Mwango had previously prepared, as well as in reference to him personally. Mr Mwango alleges that Mr Crotty repeatedly swore at him, shouted and banged his hands on a nearby bench. Mr Mwango gave evidence that he responded to Mr Crotty's alleged conduct by saying "please just talk to me nicely and stop swearing".
[32] Mr Mwango denies that he was aggressive, pointed at Mr Crotty or said "you better be Caref". Mr Mwango cannot recall raising his voice.
[33] Mr Mwango denies that he said he would repay Mr Crotty back; however, he admits that he said words to Mr Crotty to the following effect:
"Now the line has been crossed if you think that is the appropriate language we should be using at work then from today onwards I will be using the same language as him. But I will be stepping it up, if you give me 100% I will give you 110%, 120% more."
[34] During cross-examination, Mr Mwango explained that when he said to Mr Crotty "I will be stepping it up. If you give me 100 per cent I will give you 110" he meant:
"… if you swore at me like that, he said he was swearing at me, I will swear to him in a way that you'll feel bad, you'll feel worse".
[35] Mr Mwango denies that Mr Crotty walked away from him after he said this.
21 The Commissioner stated that, after considering all of the documentary and oral evidence in relation to the incident of 17 August 2017, he preferred the evidence given by Mr Crotty summarised at D[24] to [27]. He gave detailed reasons for preferring Mr Crotty's evidence at D[36] (footnotes omitted, emphasis in original):
[36] Having considered all of the documentary and oral evidence in relation to the 17 August 2017 incident I prefer the evidence given by Mr Crotty as summarised in paragraphs [24] to [27] above for the following reasons:
(a) First, there is a high level of consistency between the initial statement Mr Crotty gave to WesTrac dated 17 March 2017, his witness statement dated 26 February 2018 and filed in these proceedings and the oral evidence he gave at the hearing. Further, although Mr Crotty was shaken as a result of his interactions with Mr Mwango on 17 August 2017, Mr Crotty answered the questions put to him in cross examination by Mr Mwango in a direct and responsive manner and gave his oral evidence in a measured way;
(b) Secondly, Mr Crotty's evidence (as summarised in paragraphs [24] to [27] above) is broadly consistent with evidence given by Mr Lai, who I accept witnessed much of the incident on 17 August 2017 (see paragraph [75]). For example, although Mr Lai's account is that Mr Mwango said words to the effect of "I will repay back 100, 1000 time worse to you etc." whilst pointing at Mr Crotty, shaking and clenching his fists (see paragraph [28] above), his account is still broadly consistent with Mr Crotty's evidence that Mr Mwango said that he could expect "payback" in a raised voice whilst aggressively gesturing towards him. Further examples of the broadly consistent evidence of Mr Crotty and Mr Lai include (i) Mr Crotty describing the calibration results as being "shit", (ii) Mr Mwango saying "you better be Caref" in a raised voice, and (iii) Mr Mwango behaving in an aggressive and threatening manner. In my opinion, the minor inconsistencies between the evidence given by Mr Crotty and Mr Lai are not a reflection of their credibility as witnesses and are explicable as a result of the passing of time since the incident on 17 August 2017. Although I accept Mr Lai gave credible evidence to the best of his recollection, his recollection of the 17 August 2017 incident was not as clear as Mr Crotty's recollection. Indeed, during cross-examination, Mr Lai admitted that his recollection was "cloudy"(see paragraph [29] above), which is understanding given the passage of time since the incident and the fact that, unlike Mr Crotty, Mr Lai was not on the receiving end of the aggressive and threatening behaviour on 17 August 2017. Therefore, I prefer the evidence given by Mr Crotty as summarised in paragraphs [24] to [27] above to that given by Mr Lai;
(c) Thirdly, I do not accept Mr Mwango's contention that Mr Crotty and Mr Lai colluded in the preparation of their evidence. I accept as credible the denials by Mr Crotty and Mr Lai that they did collude. Their denials in that regard are supported by the different accounts given by each of them, both in their witness statements and in oral evidence, about some of the details of what happened on 17 August 2017. By way of example, Mr Crotty recalls Mr Mwango saying words to the effect of "you can expect payback 150 percent", whereas Mr Lai's recollection of that part of the conversation is that Mr Mwango said words to the effect "I will repay back 100, 1000 time worse to you"; and
(d) Fourthly, Mr Mwango's accounts of the 17 August 2017 incident provided in his statement to WestTrac sent on 29 August 2017, his statement in chief served on 12 February 2018 and his statement in reply served on 12 March 2018, contain many inconsistencies. For example, in Mr Mwango's statement to WestTrac sent on 29 August 2017, he alleges that Mr Crotty said to him "I do not care about whatever fucking shit you are telling me, your results were shit" to which he responded "please just talk to me nicely…" Whereas in Mr Mwango's statement in chief, he alleges that Mr Crotty said words to the effect of "you fucking shit, fucking cunt, shit" repeatedly, to which he responded "please just talk to me nicely…" In my opinion, the statement "I do not care about whatever fucking shit you are telling me, your results were shit" cannot fairly be described as words to the effect of "you fucking shit, fucking cunt, shit". Although the statement contains the words "shit" and "fucking", these words are not directed to Mr Mwango personally nor does the statement contain the word "cunt". Another example of an inconsistency in Mr Mwango's evidence is what he alleges he said in retaliation, or in 'standing up' (as he describes), to Mr Crotty. In Mr Mwango's statement to WestTrac sent on 29 August 2017, he alleges he said in retaliation to Mr Crotty "… from today onwards I will be saying the same language he uses at me, I will be giving back at you actually more than you do it to me I will be giving back to you more than 100 percent, now the line has crossed I won't be tolerating your nonsense and will be giving you back more 150 percent and see how you will like it". Although I accept that Mr Mwango's evidence in this respect is broadly consistent with that adduced in his statement in chief (see paragraph [33]), I do not accept that it is consistent with the evidence given by Mr Mwango in his statement in reply, in which he asserted that he said words to the effect of "If you swear at me, I will swear at you" in retaliation to Mr Crotty. A further inconsistency in Mr Mwango's evidence was that, in his statement in chief, he alleges that he said to Mr Crotty "You stinking idiot. You stink if you do not know as old as you are cannot express yourself properly apart from swearing?" This evidence does not appear in Mr Mwango's statement to WesTrac sent on 29 August 2017. This inconsistency was raised with Mr Mwango during cross-examination. Mr Mwango maintained that he said to Mr Crotty "You stinking idiot. You stink if you do not know as old as you are cannot express yourself properly apart from swearing?"- but denied that his failure to include this part of the conversation in his 29 August 2017 statement gave rise to an inconsistency because in that statement, he asserted that he said to Mr Crotty words to the effect of "if it is the language that he understands then you stinking idiot get out face". I do not accept that this evidence is objectively consistent. Although some allowance must be made for the fact that Mr Mwango was self-represented throughout the material parts of these proceedings, the inconsistencies in Mr Mwango's evidence, as well as his refusal to accept such an inconsistency when brought to his attention, negatively affects his credibility as a witness.
22 At D[37], the Commissioner concluded that the incident occurred as summarised at D[20] to [27] and that:
I am also satisfied that Mr Mwango's conduct during the 17 August 2017 incident was in breach of the Code and inconsistent with the Procedure for the following reasons:
• The Code obliged Mr Mwango to ensure that his personal conduct and behaviour was at all times professional (and lawful). The conduct Mr Mwango engaged in on 17 August 2017 was unprofessional. It was inappropriate and threatening.
• The Procedure required Mr Mwango to behave in an acceptable manner. Mr Mwango engaged in unacceptable behaviour by physically threatening and showing aggression to Mr Crotty.
23 When assessing whether the applicant had been provoked on 17 August 2017, the Commissioner made the following further findings of fact (footnotes omitted):
[74] The catalyst for the incident between Mr Mwango and Mr Crotty on 17 August 2017 was Mr Crotty's use of the word "shit". According to Mr Mwango, Mr Crotty said the word "shit" in reference to results that Mr Mwango had previously prepared, as well as in reference to him personally. According to Mr Crotty, he said the word "shit" in reference to the initial results as opposed to Mr Mwango personally or Mr Mwango's work. Although it was not quite put in this way by Mr Mwango in his submissions, it is possible that Mr Crotty's use of the word "shit" provoked Mr Mwango to act in the way he did.
[75] Mr Lai corroborated Mr Crotty's evidence that he used the word "shit" to describe results. Mr Lai gave evidence that when he entered the Laboratory he heard Mr Crotty say words to the effect of "the calibration is shit". Although Mr Mwango and Mr Crotty both gave evidence that they believe Mr Lai entered the Laboratory at a later stage in the discussion, I accept Mr Lai's evidence that he heard Mr Crotty say words to the effect of "the calibration is shit". During cross-examination, Mr Mwango accepted that it could have been the case that Mr Lai was standing in the doorway of the Laboratory and he did not notice. Indeed, I am satisfied that both Mr Mwango and Mr Crotty did not realise that Mr Lai had entered the Laboratory until he walked over to them and/or said something to them.
24 The Commissioner made the following factual findings about conduct after the incident and whether the applicant was notified of the reasons for his dismissal and given an opportunity to respond (footnotes omitted):
[41] On 23 August 2017, Mr Mwango attended a meeting with Ms Fletcher and Mr Ward at the Tomago WesTrac site. At this meeting, Mr Mwango was provided with a letter dated 23 August 2017 (Stand Down Letter) which stated:
"Dear Bernard,
Stand down pending investigation
This letter serves to confirm our conversation from today, in which you were advised that you will be stood down with full pay effective immediately pending an investigation.
This investigation is in response to an incident in the lab on Thursday 17 August 2017, in which it is alleged that you made inappropriate and threatening comments to another employee.
Upon completion of the investigation, you will be given 24 hours' notice of the requirement to return to site for a meeting. This meeting will involve myself and a representative from HR where you will be given the investigation findings and asked to provide a response. During this meeting you are able to use the Employee Resolution Process (as per Company policy) and have a support person present, if you wish.
Please be aware that the outcome of this investigation may lead to disciplinary action.
A copy of this letter will be kept in your personnel file.
Yours faithfully,
Brett Ward"
[42] Although the Stand Down Letter did not set out the specific inappropriate and threatening comments (and other conduct) WesTrac relied on to terminate Mr Mwango's employment, I accept the evidence given by both Ms Fletcher and Mr Ward that Mr Mwango was orally informed of these specifics at the 23 August 2017 meeting. I also accept Ms Fletcher's and Mr Ward's evidence that Mr Mwango was asked at this meeting to provide a written statement of events by no later than 8:00am on 24 August 2017. Mr Mwango did not comply with the request.
[43] I accept Mr Ward's evidence that Mr Mwango was provided with another opportunity on 25 August 2017 to respond to the allegations upon which WesTrac relied to dismiss him. Mr Ward's email to Ms Fletcher sent at 12:03pm on 25 August 2017 supports Mr Ward's contention that he gave Mr Mwango a further opportunity to respond to the allegations:
"…I finally got a hold of Bernard by him texting me to give him a call. I asked him how he is going with the statement I asked him to produce to me 2 days ago. He informed me that he can not supply to me as I have not sent him Matthew's statement. I replied to Bernard that I never stated that he would receive a copy of his statement and this will not be occurring, he needs to supply his statement on versions of events as it actually occurred.
He then continued in saying that he has written it but will not supply unless I send him I [sic] writing that I have only stood him down and reason I have not stood Matthew down. I informed him as discussed in the last face to face meeting a decision was made to stand Bernard down as we have 2 witness statements that describe his behaviour to be in breach of WesTrac behaviour procedure… I made a decision to … give him time to respond his version of events before any possible action is taken…
I informed him that if I do not receive a statement from him I will have to act on only those statements I have received…"
[44] On 28 August 2017, Mr Mwango attended another meeting with Ms Fletcher and Mr Ward at the Tomago WesTrac site. I accept Mr Fletcher's and Mr Ward's evidence that Mr Mwango was given yet another opportunity at this meeting to respond to the allegations made against him by Mr Crotty and Mr Lai. Indeed, following this meeting, Mr Mwango sent an email to Ms Fletcher and Mr Ward at 7:34am on 29 August 2017 in which he set out his version of the events on 17 August 2017.
[45] On 7 September 2017, Mr Mwango attended a final meeting with Ms Fletcher and Mr Ward at the Tomago WesTrac site. The purpose of this meeting was to provide Mr Mwango with the outcome of the investigation. I accept M[s] Fletcher's and Mr Ward's evidence that Mr Mwango was again notified of the allegations made against him and that he was given yet another opportunity to respond to those allegations.
25 The applicant had argued that he had not been afforded procedural fairness by WesTrac before his dismissal. His arguments in this regard were summarised by the Commissioner at D[65]:
[65] Mr Mwango contends that he was denied procedural fairness during the disciplinary process leading up to his dismissal for a number of reasons, including the following:
(a) Mr Ward and Ms Fletcher refused to show Mr Mwango the statements made by Mr Crotty and Mr Lai, which contained the allegations upon which WesTrac relied to dismiss Mr Mwango;
(b) Mr Ward and Ms Fletcher did not give Mr Mwango the opportunity to provide his version of events before they made the decision to stand him down pending the investigation; and
(c) Mr Ward and Ms Fletcher did not provide him with the findings of their investigation when they decided to terminate him.
26 It was not disputed that the applicant had asked WesTrac to provide him with copies of the statements and that WesTrac had refused to provide them to him.
27 At the hearing before this Court, the applicant referred to paragraph D[67] emphasising the last sentence (footnotes omitted, emphasis added):
[67] In light of my earlier findings that Mr Mwango was provided with the specifics of the allegations upon which WesTrac relied to dismiss Mr Mwango at the 23 August 2017 and 7 September 2017 meetings (see paragraph [42] and [45] above), I do not accept that Mr Mwango was denied procedural fairness by Ms Fletcher and Mr Ward refusing to show Mr Mwango the statements of Mr Crotty and Mr Lai. Mr Mwango was able to, and did, provide WesTrac with his version of the events on 17 August 2017. Although the process would have been a better one had those statements been provided to Mr Mwango, I am satisfied the process which was followed by WesTrac did not deny Mr Mwango procedural fairness.
