And under the heading "11.2.3 Delaying Maintenance", Dr Galvin further stated:
13. From the information provided to me, it is my opinion that:
· . . .
· The rules and procedures in place catered for repairing MRS1 in safe and secure circumstances.
179 While Dr Galvin's view was it was safe to stop "production" at that point, that is to stop, "mining" he did not directly give the opinion the place where the MRS1 was placed for the repair was safe rather it was his view if an employee went out from under roof support it would be unsafe.
180 This opinion of Dr Galvin's cannot be read as a statement that the place of work where the repair was conducted was safe.
181 The MRS1 was moved away from the face and left at the edge of the 7th heading which was within Panel 413 which panel was at risk of rib spall. That risk was made manifest by a rib spall in the Panel 413 before the maintenance shift began left a drop of coal which was large enough to impede the placement of the MRS1 under roof support. We accept therefore that work was, on the relevant date, being performed in Panel 413 and Panel 413 was the place of work. We further find the place where the MRS1 was moved for the repair was within Panel 413 and was susceptible to rib spall and therefore unsafe. It lay within the area described by her Honour as "hazardous".
182 With respect to her Honour, and given the totality of the evidence on this issue, we find her Honour fell into error. The place of work where the MRS1 was moved to and where the repair was conducted was within Panel 413 and was unsafe.
183 The second issue which arises on appeal was what work was being performed. The relevant particular (particular (k) asserted Mr Downes was performing "maintenance" duties. The issue which was litigated before her Honour at first instance was whether the "repair" to the MRS1 was part of "maintenance" duties being performed by Mr Downes. It was particularised that scheduled maintenance took place on the MRS1 (particular (i)).
184 While her Honour found the work Mr Downes was performing was "cleaning" work and cleaning work was maintenance work she left open the proposition that while the cleaning was maintenance work the repair of the MRS1 was a separate task and the respondent to the appeal presses the issue that there were no pleadings relevant to the assertion there was a risk of injury in the performance of the repair.
185 In a determination of the work being performed on the relevant date, her Honour gave much consideration to the placement of the MRS1. The particulars of the charge recited the machine was moved "to a position which allowed access around the MRS1 but it was not under the supported roof". This fact was never challenged. It was also conceded because of the rib spall before the shift began there was a mound of coal on the floor of the mine and that was why it was impossible to reverse the MRS1 to a position underneath roof supports. The machine was placed in a position but not fully underneath the roof support. The left side of the machine remained exposed. Mr Downes was attempting to remove coal to allow access to the MRS1 for the repair of the oil leak when he was injured by a rib spall.
186 Evidence revealed the oil leak was mentioned in the production and maintenance unit shift report; the day shift of 19 July 1999 noted "check out No. 1 MRS for oil leaks"; the afternoon shift of 19 July 1999 noted "repair No 1 MRS oil leak" and the night shift of 20 July 1999 noted "fix oil leak MRS1". The respondent submitted on appeal the work of Mr Downes was not related to the repair. The inference from this submission is the respondent was holding the prosecution to the charge as pleaded and, as no repair work was pleaded as an element of the alleged offence, the charge was not proven.
187 Cleaning out pieces of coal that had fallen beside the MRS1 was as her Honour held "undoubtedly a part of routine maintenance on the machine." Her Honour accepted the MRS1 had to be moved away from the goaf edge in order for the work on it to be undertaken. Her Honour found also that maintenance work was normally undertaken away from both the face and the goaf. Her Honour also accepted it was "cleaning" work Mr Downes was performing. The general Maintenance Shift documentation referred to "machine services" as a relevant task and the weekly service on the MRS1 required a check of oil leaks. We reject the assertion the pleadings referred to maintenance work and therefore the repair to the MRS1 was a separate task. While the repair was being performed by Mr Dodds, as the designated worker whose task was the repair of the oil leak, we find Mr Downes was assisting Mr Dodds by performing his maintenance duties. Whether the task Mr Downes was performing was cleaning or repair we accept it was part of scheduled maintenance on the MRS1 as asserted in the pleadings (particular (i)).
188 We find the particular (i) asserting Mr Downes was performing maintenance duties was established both on the evidence and by her Honour and we reject the proposition of the respondent that the acts of Mr Downes were not covered by the pleadings.
189 Once part of the MRS1 was placed outside the supported roof (as particularised) and Mr Downes was required to perform maintenance work on the machine, the respondent had an absolute obligation to ensure that all work could be performed safely. Access to the machine was vital to perform both the repair and the cleaning. Mr Downes was cleaning out coal to assist in the maintenance of the machine.
190 In going to the side of the MRS1 to remove coal or as her Honour held to clean up the coal in an area where the rib had been "trimmed" (that is, cut further to make the roadway wider) and into an area where no roof bolts had been installed, Mr Downes was clearly under unsupported roof. However, Mr Downes had to ensure as Deputy that maintenance work on the MRS1 was completed on the shift.
191 The task required Mr Downes to be alongside the MRS1. Her Honour, however, rejected that the respondent was responsible for Mr Downes being where he was. The operative cause of Mr Downes being placed at risk was he was required to perform work near the MRS1 in the form of cleaning away coal. The evidence established the MRS1 had been placed in a position and part of the machine was outside the safe supported roof in Panel 413 (Particular (h)) where the ribs were unstable and hazardous. The placement of the MRS1 was an act of the respondent for which the respondent was liable under the OHS Act and which act was relied upon in the particulars.
192 Evidence revealed it was known that coal would get caught in the "extraction" holes in the MRS1. The MRS1 would, during production, fill with coal and on occasions the cleaning took up a whole shift. Mr Dodds, the nominated worker to perform the repair, had on occasions cleaned out coal from the "extraction" holes if he had access. There was pressure on both Mr Dodds and Mr Downes to have the repair completed in order to allow the following shift, being a production shift, to start on time. Given the state of the ribs the next production shift had to be on time and there was an imperative for the Deputy to assist in the repair.
193 We are satisfied that the work being performed by Mr Downes was particularised and the evidence established Mr Downes in cleaning out the coal was performing maintenance duties.
194 The third consideration on appeal is what was the risk alleged and what acts of the respondent contributed to the risk asserted. The risk was simply put by the prosecution as "the risk of injury from rib spall".
195 A basic element of the charge as pleaded (particular (h)) - was the work being performed, namely, the maintenance work, should have been "delayed".
196 The relevant particulars ((d), (e), (f), (g) and (h)) asserted given the state of Panel 413 the under manager had the authority to delay scheduled maintenance and continue pillar extraction until a stable position was reached. Particular (b) therefore make two assertions - firstly, maintenance should have been delayed and secondly, pillar extraction, that is, "mining", should have continued. They are the assertions relied upon which, if proven, created the risk. The proposition can be positively recited, namely, the respondent should have delayed maintenance (in which the repair was a designated task) and continued mining.
197 Her Honour, with respect, recast the pleading to assert at [178] the charge was concerned with:
[178] a failure to delay the repair, not a failure to have undertaken the repair earlier . . .
