Facts
This matter involved appeal applications brought by both the employer and the worker. The employer’s appeal raised issues going to the calculation of ‘pre-injury average weekly earnings’ (PIAWE) pursuant to Sch 3 of the 1987 Act, where the worker is employed by “2 or more employers”. The worker lodged an appeal out of time, challenging a factual finding of the Arbitrator going to the amount he is able to earn in suitable employment.
On 5 December 2014, the worker injured his shoulders in the course of his employment with Woolworths. He also worked as a cleaner for Access Group Solutions (Access). He said that he resigned from the job at Access in December 2014 because of his shoulder injury. The worker continued to work for the employer on restricted duties when he resumed work following a family holiday. The problem did not settle and he claimed weekly compensation and s 60 expenses. The treating orthopaedic surgeon recommended surgery to the worker’s left shoulder and certified him as unfit until the surgery was carried out.
The Arbitrator found that it was necessary that PIAWE be calculated based on the worker’s earnings with both the employer and Access. The Arbitrator made findings that the worker was employed by both the employer (Woolworths) and Access at the date of injury, and that he was partially incapacitated for work with each of them. He applied Item 7 of the table in Sch 3 of the 1987 Act.
The figures were agreed at $939.46 (the employer, Woolworths) and $911 (Access), a total of $1,850.46. The Arbitrator accepted that the worker had a capacity to work in suitable employment, such as “the education and accountancy industries”, for 15 to 20 hours per week, with an ability to earn $600 per week. After applying the formula in s 37(3)(a) of the 1987 Act, the Arbitrator entered a weekly award at the rate of $880.36 from 12 December 2015 to date and continuing. The employer appealed, and the worker then appealed out of time.
The issues on the employer’s appeal were whether the Arbitrator erred in:
(a) finding that PIAWE should be calculated by reference to Item 7 of Sch 3 of the 1987 Act (Ground No 1);
(b) not finding that PIAWE should be calculated by reference to either Item 5 or Item 8 of Sch 3 of the 1987 Act, rather than Item 7 (Ground No 2), and
(c) calculating the PIAWE, and hence the weekly entitlement, by reference to PIAWE determined pursuant to Item 7, rather than Item 5 or Item 8 (Ground No 3).
The issue on the worker’s appeal was whether the Arbitrator erred in finding that the worker had a current ability to earn of $600 per week.
Held: The worker’s application to extend time pursuant to r 16.2(12) of the 2011 Rules was refused. As regards the Arbitrator’s decision dated 28 March 2017: paragraph 1 was amended to substitute the figure ‘$151.57’ for the figure ‘$880.36’ and paragraph 2 was confirmed.
THE EMPLOYER’S APPEAL
Ground No 1
1. The employer submitted that the worker’s PIAWE should not be calculated on the basis of Item 7, but on the basis of one of Items 4, 5 or 6 of Sch 3. ([34])
2. The Arbitrator based his finding on Item 7 of the table in Sch 3. The descriptor for Item 7 had the following elements:
(a) the worker employed by 2 or more employers;
(b) the injury resulting in incapacity for work for one or more of the employers, and
(c) the injury not resulting in incapacity for work for all of the employers. ([35])
3. Deputy President Snell looked at whether the Arbitrator’s finding, that Item 7 of Sch 3 applied, could stand with the balance of the Arbitrator’s findings. The Deputy President held that on the Arbitrator’s findings, the first two of the elements were satisfied. On the face of it, the third element was not satisfied as there was a finding of partial incapacity to work for both the employer and Access, which was “all of the employers”. ([35]–[36])
4. The Deputy President observed that there is nothing in the descriptor in Col 2, applying to Item 7, which suggests that satisfaction of any of the elements is based on either total or partial incapacity, to the exclusion of the other. The phrase is “incapacity to work”, which can involve either total or partial incapacity (Alcan (NT) Alumina Pty Ltd v Commissioner of Territory Revenue [2009] HCA 41; 239 CLR 27 at [47] and ADCO Constructions Pty Ltd v Goudappel [2014] HCA 18; 254 CLR 1 at [29] applied). ([42], [44])
5. Deputy President Snell held that the clear meaning of the text, in Col 2 of Item 7, is that application of the Item requires, as an element, that the injury did not result in incapacity to work for all of the employers. The effect of the Arbitrator’s finding was that the third of the elements required, for Item 7 to have application in the circumstances, could not be established. It followed that Ground No 1 was made out and it was necessary that the Arbitrator’s decision regarding quantification of the weekly entitlement be revoked. ([45]–[46])
Grounds Nos 2 and 3
6. The employer, in grounds 2 and 3, argued that Item 5 or Item 8 of Sch 3 should be applied in the circumstances. These effectively were arguments going to the appropriate orders to be made, if the matter was re-determined on appeal. This issue is discussed below after consideration of the worker’s appeal. ([47])
THE WORKER’S APPEAL
Application to extend time in No A2-6636/16
7. The worker required leave to extend time in the Appeal lodged on 19 May 2017, leave to rely on an Amended Appeal lodged on 30 May 2017, and leave to rely on fresh evidence attached to the Amended Appeal. ([54])
8. The worker’s appeal was registered a little more than three weeks out of time. The sole basis put forward by the worker, to explain the delay, was that it was arguable that his appeal would not pass the threshold in s 352(3) of the 1998 Act. Deputy President Snell held that the variation to the weekly entitlement, sought in the worker’s appeal, substantially exceeded the threshold sum of $5,000 referred to in s 352(3)(a). The worker’s submissions did not contain any calculations going to the threshold in s 352(3)(b). ([59])
9. Section 352(3)(b) requires that the amount of compensation at issue on the appeal be at least 20 per cent of the amount awarded in the decision appealed against. The amount of compensation at issue in the worker’s appeal, based on the weekly award as entered by the Arbitrator, was about 30 per cent of the weekly compensation awarded. If one had regard to the award for medical expenses and the sum specifically claimed for surgery in the Application, this percentage reduced to about 25 per cent. Deputy President Snell noted that there were no specific submissions made by the worker, which identified how the threshold in s 352(3) represented an impediment to commencing the appeal in time. He concluded that the extent of the delay, and the reasons for the delay were not adequately explained. The Deputy President further found that the worker’s submissions did not deal with whether ‘exceptional circumstances’ were present. He held that doubt in the minds of those advising the worker, about whether the thresholds in s 352(3) were met, did not constitute ‘exceptional circumstances’ (Yacoub v Pilkington (Australia) Ltd [2007] NSWCA 290 at [66] applied) (Bryce v Department of Corrective Services [2009] NSWCA 188 referred to). ([60], [62])
10. Deputy President Snell stated that it was necessary to have regard to the prospects of success of the worker’s proposed appeal. The Deputy President noted that leave was required under s 352(6) to admit fresh evidence in the form of 3 payslips, which went to the worker’s actual earnings in the education industry. He found that the worker could not establish a basis to admit the fresh evidence applying the first limb in the test in CHEP Australia Limited v Strickland [2013] NSWCA 351; 12 DDCR 501 (Strickland) at [27] and [31]. There was no indication that reasonable steps had been undertaken to obtain the payslips prior to the hearing before the Arbitrator, such as by contacting the company, by letter or in person, and seeking copies. There was no indication that this was done or with what result. ([65], [67]–[70])
11. The Deputy President further held that the worker would not satisfy the second limb in the test in Strickland. Section 35 provides for the computation of ‘E’, in the equations under ss 36 and 37 of the 1987 Act. ‘E’ was calculated by the Arbitrator on the basis of “the amount the worker is able to earn in suitable employment”, rather than “the worker’s current weekly earnings”. The fresh evidence in the payslips, if admitted, would not change the figure attached to ‘E’ in the circumstances. The attachment of a monetary value to the worker’s earning capacity was consistent with the Arbitrator’s status as a member of a specialist tribunal, taken to have knowledge of the labour market and wages (J & H Timbers Pty Ltd v Nelson [1972] HCA 12; 126 CLR 625; Cowra Shire Council v Quinn [1996] NSWSC 143; (1996) 13 NSWCCR 175; Australia Pty Ltd v Cassells (1995) 25 NSWCCR 385; Iron & Steel Pty Limited v Elliott (1966) 67 SR (NSW) 87; Goktas v Goodyear Australia Pty Limited [2007] NSWWCCPD 1 at [32]; Forests NSW v Hancock No.2 [2007] NSWWCCPD 191 at [76], and Perkins v Ceva Materials Handling Pty Ltd (previously TNT Materials Handling Pty Ltd) [2011] NSWWCCPD 32 at [75] applied). ([78]–[80])
12. It followed that the worker’s application to rely on fresh evidence, in the Amended Appeal, could not succeed. The fresh evidence would satisfy neither of the limbs in Strickland. It additionally followed that the worker would not be granted leave to rely on the Amended Appeal, as this would be futile. The worker’s prospects of success in his appeal were evaluated by the Deputy President without reference to the fresh evidence. ([82])
13. Deputy President Snell held that the worker’s appeal did not have reasonable prospects of success. The Deputy President stated that the Commission is a specialist tribunal, with knowledge which equips it to make assessments on the worker’s ability to earn. He held that the Arbitrator’s reasons for his findings on the worker’s ability to earn were adequate (Beale v Government Insurance Office of NSW (1997) 48 NSWLR 430 at 444 applied). ([90])
14. Deputy President Snell concluded that delay was not adequately explained, ‘exceptional circumstances’ were not established, and the appeal lacked reasonable prospects of success. The factors did not favour the extension of time for the bringing of the worker’s appeal. The appropriate order was that the application to extend time be refused. ([91])
RE-DETERMINATION
15. It was appropriate that the issue of weekly entitlement be re-determined on appeal. Deputy President Snell held that Items 1, 3, 4, 6, and 9 of Sch 3 did not apply. The worker satisfied the first two requirements in Items 2 and 5. On balance, the Deputy President concluded that the appropriate factual finding (and it was consistent with the employer’s submission) was that Item 5 of Sch 3 applied, and the relevant PIAWE figure was $939.46. Applying the equation in s 37(3) of the 1987 Act, this yielded a weekly entitlement of $151.57 (80 per cent of the PIAWE less the found ability to earn of $600). ([92]–[99])
A FURTHER MATTER
16. Deputy President Snell observed that identification of the ‘Class of worker at time of injury’, for the purposes of Items 2, 3, 4, 5 and 6, involves reference to the worker’s hours of employment, having regard to whether s/he worked for at least the prescribed number of hours (38 per week) and/or at least the applicable hours fixed in any applicable fair work instrument, in one or more of the employments. Whether there is any applicable fair work instrument, and the hours worked pursuant to that instrument or otherwise, are fundamental to identifying an appropriate Item in Sch 3. The Deputy President stressed that it is important that parties specifically address the issues raised by Sch 3 of the 1987 Act, in the evidence lodged in matters where there are “2 or more employers”.

Facts
The worker suffered a traumatic injury to her ear. As a result she suffered tinnitus. She claimed compensation for the cost of treatment for her condition. It was not in dispute that pursuant to s 59A(2)(a)(i) of the 1987 Act, the worker ceased to be entitled to compensation as more than two years had elapsed since she first claimed compensation. The dispute concerned the application of s 59A(3) of the 1987 Act and whether the worker’s entitlement to compensation could be revived due to the need for further treatment and the associated time away from work whilst undergoing treatment.
The worker made a claim in respect of past hospital, medical and rehabilitation expenses, and proposed future treatment. The employer’s insurer did not accept the claim for future treatment and the matter came before a Commission Arbitrator.
The Arbitrator was satisfied that the proposed future treatment was reasonably necessary and related to the accepted injury. However, as more than two years had elapsed since a claim for compensation was first made in respect of the injury, the worker was excluded, pursuant to s 59A(2)(a)(i), from recovering the compensation claimed. Further, the Arbitrator was not satisfied that s 59A(3) applied because the worker had failed to discharge the onus of establishing that she would be incapacitated and entitled to compensation whilst undertaking treatment.
The worker appealed. The issues on appeal concerned whether the Arbitrator erred in:
(a) her analysis of the medical and factual evidence in making a finding of fact, in the course of a determination pursuant to s 59A of the 1987 Act, that the worker would not be relevantly entitled to weekly payments of compensation as a consequence of a compensable incapacity for her pre-injury employment, and
(b) failing to give “proper reasons” for her findings.
Held: The Arbitrator’s determination was confirmed.
Consideration
1. Consistent with Flying Solo Properties Pty Ltd t/as Artee Signs v Collet [2015] NSWWCCPD 14 (Collet), the Arbitrator found that whether the worker may have an “incapacity” when attending the clinic for treatment is not determinative of whether or when weekly compensation is “payable”. ([60])
2. The Arbitrator also found correctly, and consistent with Collet, that should the worker proceed to have the proposed treatment at her own expense and require time off work for the treatment, if medical certificates were submitted at that time in support of a claim for weekly compensation, compensation would once again become payable to her and the insurer would be obliged to meet the cost of the treatment as it has been found to be reasonably necessary. ([61])
3. The appellant submitted that the Arbitrator made several factual errors. Those submissions were against the weight of the evidence and were rejected. ([62]-[65])
4. The appellant’s submission that the Arbitrator erred by applying s 37 of the 1987 Act, when s 36 of the 1987 Act was the relevant provision, was rejected. The Arbitrator concluded that, because of an absence of evidence, no entitlement to compensation under s 36 had been established. The submission failed to provide any reasoned argument to support the alleged error. It followed that the appellant’s submission that the application of the formula in s 36 would entitle her to an award of compensation could not be entertained. ([66]-[67])
Adequacy of reasons
5. The appellant submitted that the Arbitrator failed to give proper reasons for her findings. No submissions were made in support of this ground. ([68])
6. The President considered the nature of an Arbitrator’s duty to give reasons and the standard by which the adequacy of reasons must be determined (s 294(2) of the 1998 Act, r 15.6 of the 2011 Rules; NSW Police Force v Newby [2009] NSWWCCPD 75; Mayne Health Group t/as Nepean Private Hospital v Sandford [2002] NSWWCCPD 6; Beale v Government Insurance Office (NSW) (1997) 48 NSWLR 430 applied). ([69]-[72])
7. The President was satisfied that the Arbitrator discharged the statutory obligation to provide reasons. The path of reasoning which led the Arbitrator to her ultimate conclusion was clearly stated. Namely, the absence of evidence concerning the number of hours the worker worked per week or any evidence concerning her regular hours of work. This coupled with an absence of evidence concerning the operating hours of the audiology clinic where she would undergo the proposed treatment, and the absence of any medical certificates of incapacity, led the Arbitrator to conclude that the worker had failed to discharge the onus of proving incapacity and an entitlement to weekly compensation whilst undergoing treatment. It followed that in those circumstances s 59A(3) did not operate to revive the worker’s entitlement to the compensation claimed. ([73])
Birbiri v First Choice Removalz Pty Ltd [2017] NSWWCCPD 37
Error of fact; application of the principles discussed in Whiteley Muir & Zwanenberg Ltd vKerr (1966) 39 ALJR 505 and Fox v Percy [2003] HCA 22; 214 CLR 118
Keating P
30 August 2017
Facts
This matter involved a challenge to an Arbitrator’s factual finding that the worker did not sustain an injury to his back in the course of his employment as a removalist with the respondent, when he moved a large steel cabinet on 19 February 2016.
The worker claimed that he woke up the next morning with severe low back pain and had difficulty walking. The worker attended his uncle’s wedding that day, however he claimed that he sat down most of the night, did not dance, and left early.
On 22 February 2016, the worker allegedly called his employer and informed him of the injury and stated that he would not be able to return to work. He did not return to work.
The worker’s employer prepared a chronology of events, which included an entry for 22 February 2016 which recorded a text exchange confirming hourly rate was sent to the worker and a comment by the author that there was no mention of any injuries.
On 24 February 2016, the worker attended a chiropractor complaining of low back pain. On that same day, he sent his employer a text message stating that he had seen a chiropractor who said he had to rest for a minimum of four days. In a separate text message the worker attached the certificate. That certificate recorded that the worker was treated for acute low back pain which came on two days earlier (i.e. 22 February 2016) after lifting some heavy objects whilst at work.
The worker’s other medical evidence recorded an injury date of 23 February 2016. However, the worker later sought to correct this error and submitted that it wasn’t until he looked back over the dates that he realised the error and sought to correct it.
It was accepted that the worker sustained an injury to his back but the mechanism and date of injury were disputed.
The issues on appeal concerned whether the Arbitrator erred in:
(a) finding that the worker had not suffered a work injury in the course of or arising out of his employment with the respondent, and
(b) making an adverse finding as to the creditworthiness of the worker.
Held: The Arbitrator’s determination was confirmed.
Consideration
1. The President observed that the appellant sought to challenge the Arbitrator’s factual finding, which could only be overturned where error is established. (Whiteley Muir & Zwanenberg Ltd v Kerr (1966) 39 ALJR 505; Raulston v Toll Pty Ltd [2011] NSWWCCPD 25; 10 DDCR 156; Branir Pty Ltd v Owston Nominees (No 2) Pty Ltd [2001] FCA 1833 considered). ([57]-[58])
2. The President also observed the following principles in Fox v Percy [2003] HCA 22; 214 CLR 118. Error will be found where there were “incontrovertible facts”, or other “uncontested testimony” demonstrating the error (at [28]). The finding may be “glaringly improbable” or “contrary to compelling inferences” in the case (at [29]). The mere appearance of witnesses - that is, their demeanour - as a determinant of truth is now cautioned against as a means of making findings of fact (at [30]). Trial judges are urged to pay more attention to the “apparent logic of events”, the existence of “contemporary materials”, and other “objectively established facts” as a means of reasoning to a conclusion (at [31]). ([59])
3. Applying the above principles to the facts, the President did not accept the worker’s submission that the text message exchange on 22 February 2016 was only explicable in the context of an earlier report of injury having being made. The incontrovertible facts that weighed against that submission was that the text message concerned a request by the worker for information concerning his rate of pay. It did not make any reference to any alleged injury. ([60]-[61])
4. Contrary to the appellant’s submission, the President found that the entry “no mention of any injuries” in the chronology of events submitted by the worker’s employer was merely commentary of the author. It did not support the proposition that it must be inferred that the text message exchange on 22 February 2016 was consistent with an earlier report of injury. The note simply drew attention to the absence of a report of any injuries in the relevant text message exchanges. ([62])
5. The President found that the first recorded history of the injury, namely to the chiropractor on 24 February 2016 of lifting some heavy objects at work, was inconsistent with the mechanism of injury sought to be relied upon, namely moving a large steel cabinet. ([64]-[65])
6. The President rejected the submission that there had to be “real doubts” about the reliability of the recollection of the worker’s employer. The preciseness of the hours worked, the timing of text messages down to the exact minute and the record of the time at which texts messages were received, demonstrated that, in all probability, it was prepared with access to the history of the text message exchanges and perhaps other materials occurring between February 2016 and March 2016. ([66])
7. The Arbitrator assessed the reliability of the worker against “contemporary materials, objectively established facts and the apparent logic of events” (Fox v Percy). Not only was there an issue with respect to the date of the occurrence of the alleged injury but when the matter was first reported the most contemporaneous medical records provide a description of injury which was not consistent with the worker’s allegations. There was no evidence to support the submission that the reporting of the date of injury could be explained by the worker being a “rather disorganised individual”, accordingly it was rejected. ([67]-[68])
8. The President rejected the submission that the text message exchanges and the chiropractor’s certificate should have led to the Arbitrator to conclude that the worker discharge the onus of proof. The text message exchanges made no reference to the alleged injury and were not consistent with an injury having occurred as alleged. ([69])
9. The President observed that the absence of medical treatment on 20 February 2016, immediately after the alleged incident, and the worker’s attendance at a social function appeared inconsistent with his description of intense pain, allegedly limiting his ability to walk. ([71])
10. The Arbitrator did not accept the worker’s evidence regarding the date and circumstances of the alleged injury. The Arbitrator’s findings were consistent with the contemporaneous evidence including the history initially provided by the worker to his chiropractor whom he saw within days of the alleged injury. It was also consistent with the information provided in the worker’s claim form and histories to treating doctors, which indicated that if an injury did occur, it did not occur on the day the worker alleged. No error of the kind discussed in Fox v Percy or Whiteley Muir was demonstrated. For these reasons the appeal was unsuccessful. ([72]-[74])

Facts
In April 2013, the worker suffered a significant injury to her right wrist and hand when she slipped on ice on the floor of the chiller room at the appellant employer’s premises. She underwent surgery on her right wrist.
The worker claimed that as a result of the immobilisation of her right arm she suffered a consequential condition in the right shoulder, namely adhesive capsulitis (frozen shoulder), nerve damage and complex regional pain syndrome. The appellant accepted liability in respect of the right wrist but did not accept liability for the consequential condition in the right shoulder.
The matter came before a Commission Arbitrator. During proceedings the appellant placed significance on “the bin incident”, which was recorded in clinical notes in July 2013. The clinical notes recorded that the worker jarred her right shoulder again (dodging bin lid). The appellant argued that the bin incident provided a commonsense explanation, for the right shoulder injury, that was both temporal and credible.
The Arbitrator found for the worker in respect of the right shoulder. The employer appealed.
The issues on appeal concerned alleged legal, factual and discretionary error in finding that the worker’s right shoulder condition was causally related to her right wrist injury.
Held: The Arbitrator’s determination was confirmed.
The test of causation
1. The appellant submitted that the worker, in discharging her onus on causation, must establish that the wrist injury “materially contributed” to the right shoulder condition. It was submitted that this involves a medical question and the “commonsense approach” to causation but could not excuse the Arbitrator’s failure to address either a conflict in the medical evidence or the absence of medical opinion. ([112])
2. The President observed that it is generally accepted that a party is bound by the conduct of his case at first instance and it would be contrary to all principle to allow a new argument to be considered after the case has been decided (Metwally v University of Wollongong [1985] HCA 28; 60 ALR 68; 59 ALJR 481; Australia and New Zealand Banking Group Ltd v Haq [2016] NSWCA 93). He also observed that an Arbitrator cannot have erred in failing to deal with an argument that was not put during the course of the hearing (Brambles Industries Ltd v Bell [2010] NSWCA 162; 8 DDCR 111). As the appellant’s submission on the “material contribution test” was not argued before the Arbitrator, the President did not entertain it. ([113]-[114])
The factual findings
3. The Arbitrator analysed the factual evidence at length and made a series of factual findings regarding the worker’s symptoms of her right wrist and shoulder, her return to work, and, amongst other things, disuse of the right arm. The President found these factual findings to be open on the evidence presented and revealed no error. He observed that it was with the background of these factual findings that the Arbitrator analysed the medical evidence. ([115]-[116])
The medical evidence
4. Contrary to the appellant’s submissions; the President found that Dr Challender’s knowledge of symptoms pre-existing the injury in April 2013, his acknowledgement of the worker’s involvement in the bin incident and his ongoing treatment over a lengthy period, provided a fair climate for the acceptance of his unequivocal opinion supporting a causal connection between the right shoulder condition and the accepted wrist injury (Paric v John Holland (Constructions) Pty Ltd [1985] HCA 58). ([117]-[119])
5. The President did not accept the appellant’s submission that Associate Professor Fearnside did not express an opinion on causation. He included in his assessment of impairment referable to the April 2013 injury an assessment of WPI in relation to the condition of the shoulder. The Arbitrator concluded that the Associate Professor’s assessment that the worker “subsequently” developed chronic pain syndrome was an expression of opinion that the injury and probable consequent loss of use was capable of causing symptoms in the right shoulder. The Arbitrator expressly acknowledged that the Associate Professor did not record any history of complaints between the wrist injury of April 2013 and the bin incident of July 2013 or make any reference to the bin incident. However, notwithstanding the deficiencies in the Associate Professor’s evidence, as the Arbitrator noted, his ultimate opinion provided general support for the opinions expressed by Dr Challender. Those findings were open and did not reveal error. ([120]-[125])
6. The President did not accept the appellant’s submission that the Arbitrator rejected Dr Edwards’ opinion. The Arbitrator expressly stated that he accepted Dr Edwards’ views at least in so far as they threw some doubts as to the nature and extent of the pathology in the right shoulder resulting from the wrist injury as opposed to pre-existing conditions. This assessment went to the weight attached to Dr Edwards’ evidence. ([126])
7. The President observed that the Arbitrator identified a number of factors that diminished the weight to be attached to Dr Edwards’ opinion. Those factors included: there being no record of measurements of the upper extremities on clinical examination; a record that the worker used her left hand for most activities which supported an inference of relative disuse of the right hand when she was right hand dominant; application of the wrong legal test as to causation; failure to consider the worker’s allegation that the right shoulder condition was due to the immobility and disuse of the limb as a result of the effects of the injury to the right wrist and treatment. Rather, Dr Edwards expressed a view that the shoulder complaints were not reasonably related to surgery or the injury in April 2013. ([127]-[132])
8. The appellant submitted that the bin incident provided both a temporal and credible explanation for the worker’s symptoms which were not adequately explained by the worker or through the medical evidence. ([133])
9. Notwithstanding the absence of recorded complaints of right shoulder problems immediately after the April 2013 incident and before the bin incident in July 2013, the Arbitrator accepted that the wrist problems were the focus of the worker’s treatment and accepted the worker’s evidence of disuse of the right arm and shoulder after the initial incident and subsequent surgery. The Arbitrator also accepted that the worker more than likely experienced an increase in discomfort in her right shoulder as a result of lack of use between April and July 2013. He found that the lack of use was a result of the wrist injury and that the effect of the bin incident was less significant. Those findings were open and did not reveal error. ([135]-[136], [138]-[139])
10. The President observed, as correctly concluded by the Arbitrator, contemporaneous corroboration is not a prerequisite for the worker to succeed (Department of Aging, Disability and Home Care v Findlay [2011] NSWWCCPD 65; The Presbyterian Church (New South Wales) Property Trust v Pingol [2014] NSWWCCPD 80).
