Despite his assertion that he had ceased to be a director of Unistyle in 1989, Mr. DeSilva signed his letter above the typed words, "B. Silva M. Director."
34 Although the quote was said to include all materials, crane hire and other incidental expenses, and although Mr. DeSilva ordered the new corrugated iron from K. M. T. Metal Fabrications (BAB 20-21) and appears to have arranged for the hire of a crane, it is clear that Unistyle did not itself pay K.M.T. Metal Fabrications or "Botany Crane", which appears to have hired the crane for the purposes of the job, but was provided by the accountant at Universal's premises with a cheque or cheques to pay for the materials and the crane hire (BAB 21, 44) - this, so it seems (BAB 20), had occurred on previous occasions, albeit that the cheques which were provided for materials were not always provided by Universal.
35 The work of removing the old roofing iron and replacing it with the new iron appears as if it may have commenced on or about 3 December 1990, that is, about a week prior to Mr. Almeida's accident (BAB 22). It would seem (BAB 29) that Unistyle's workforce comprised some six people divided into two teams, one including Mr. DeSilva and the other including Mr. Almeida, those teams working on opposite sides of the roof over that part of the building in which the manufacturing area was located (BAB 24). Although, according to Mr. DeSilva (BAB 23), there were safety harnesses on the site - which harnesses, however, were not worn by the men working on the roof (BAB 28) - there were no safety nets places underneath where the work was to be carried out despite the fact that the roof appears to have been approximately 12-13 metres above ground level (BAB 31) nor was any scaffolding placed under the roof and the roof was not fenced. According to Mr. DeSilva (BAB 34-35) it would not have been possible to remove and replace the roofing iron from underneath and, working as they did, the workman would not have had anything to which they could connect safety harnesses
36 Although it is not entirely clear, it would seem (BAB 23, 26) that the system of work adopted by each of Unistyle's teams involved removing the old roofing iron, one sheet at a time in a row, and replacing that sheet with a new sheet of roofing iron from a stack which had been lifted onto the roof - there was thus, for a short time while the old iron was thrown to the ground and before the new iron was reached from the stack when there was a void in that part of the roof where the team was working. According to Mr. DeSilva (BAB 34) that method of working had been decided upon by the various members of the teams following discussion by all of them.
37 Mr. DeSilva claimed (BAB 24-25) that, because of the method of working which was adopted, it was his practice each day "(to) have a discussion with (the) person from what (he understood) to be Supre in relation to where they should or should not be when (Unistyle's) men were working" as he did not wish to have anyone working directly below in case something fell - those instructions, so he said, were carried out.
38 Although, in the course of his Judgment (RAB 26), Patten DCJ wrote "(d)uring the progress of the work at the premises prior to 10 December 1990, according to Mr. DeSylva (sic) Mr. Montebello came out 'once or twice', including on one occasion about a week before the accident", it is clear (BAB 22) that what his Honour wrote did not accord with Mr. DeSilva's evidence; on the contrary (BAB 28) Mr. DeSilva at no time saw Mr. Montebello at the site although he (Mr. DeSilva) said that, on one occasion, Mr. Montebello told him that he went past the site on his way home to have a look at how the job was progressing. It is equally clear (BAB 37) that Mr. DeSilva had total control of the job, that Unistyle's employees were subject to his control only and that Unistyle's employees would only follow his (Mr. DeSilva's) instructions.
39 Mr. DeSilva did not witness the accident as, at the time, he was working on one side of the ridge in the roof while Mr. Almeida was working on the other side of the ridge. However, "(he) heard a big scream and one of the men yelled out that Mr. Almeida had fallen down the roof" (BAB 29) and he then ran to the spot where Mr. Almeida had fallen and, when he saw where Mr. Almeida lay on the floor, he descended from the roof in order to render such assistance as he was able. Although Mr. DeSilva did not witness the accident, he noted that, at the place where Mr. Almeida fell, the hole in the roof was but the size of a single sheet of corrugated iron, and the sheet which had been removed was only about one metre away from the hole (BAB 30).
40 It would appear (BAB 36) that, after Mr. Almeida's fall, the work of re-roofing was stopped for about one or two weeks - during that period, so it would seem, no attempt was made to apply any form of temporary cover to the hole in the roof.
41 It would seem (BAB 119) that a claim for compensation was made on behalf of Mrs. Almeida on 11 December 1990 and that inquiries were made of Mr. DeSilva with a view to ascertaining the name of Unistyle's workers compensation insurer. At the time, so it would seem, Mr. DeSilva advised that "he was insured by GIO" (BAB 118), although the fact was that Unistyle's workers compensation insurance had lapsed in 1988.
42 Thereafter, at some time which, save that it must have been in the latter part of December 1990, does not appear from the materials which are before the Court, an Application for Determination was filed in the Compensation Court on behalf of Mrs. Almeida, to which application Unistyle and Workers Compensation and Rehabilitation Authority - of which the WorkCover Authority is, in the WorkCover Administration Act 1989 Schedule 4, which came into operation on 1 January 1990, said to be "a continuation of, and the same legal entity as" the Workers Compensation Rehabilitation Authority constituted under the Workers Compensation Act 1987 and the State Compensation Board constituted under that Act before the constitution of the Workers Compensation Rehabilitation Authority - were then joined as Respondents.
43 Despite Mr. Almeida's fall, no nets were installed under the roof of the large building which was being re-roofed when the work resumed - this, so it seems to be suggested (BAB 36),because it was not possible to obtain nets of a sufficient size to span the distance between the external walls of the building. However, after the larger of the two buildings had been re-roofed, nets were acquired and used while the re-roofing of the smaller building was carried out. At first (BAB 28-29),Mr. DeSilva said that the nets were acquired at the instigation of Mr. Montebello. However, in the course of his cross-examination (BAB 38),Mr. DeSilva said that it was he who thought nets should be obtained, that it was he who had ordered the nets and that Universal had paid for the nets because Unistyle was in financial difficulties.
44 At the work of re-roofing progressed, Mr. DeSilva submitted progress claims (Exhibit B - BAB 42), which progress claims were met by cheques drawn by Universal (BAB 43) the last of those payments having apparently been made on 17 January 1991 (BAB 44).
45 At some time which is not clear, but which Mr. DeSilva said he thought "was just after the accident" (BAB 32), Unistyle went into liquidation.
46 It would appear that, at some time prior to June 1991, Mrs. Almeida's solicitors became aware of the fact that Unistyle's quote for the re-roofing of the premises at 1A Sydney Steel Road, had been addressed to Universal and that the progress payments had been paid by Universal. That this was so is suggested by the fact that, in about June or July 1991, there was filed in the Compensation Court, a proposed Amended Application for Determination (Exhibit M - BAB 116-124), to which proposed Amended Application for Determination there were joined as Respondents, in addition to Unistyle, the WorkCover Authority and Universal, the basis upon which Universal was alleged to be liable for compensation being said to be "pursuant to the provisions of Section 20 of the Workers Compensation Act, 1987".
47 It is convenient to pause here for the purpose of recording that s.20 of the Workers Compensation Act 1987 ("the Compensation Act") provides (inter alia) as follows:
"20 Principal liable to pay compensation to workers employed by contractors in certain cases
(1) If any person (in this section referred to as the principal ) in the course of or for the purposes of the person's trade or business, contracts with any other person (in this section referred to as the contractor ) for the execution by or under the contractor of the whole or any part of any work undertaken by the principal, the principal is, if the contractor does not have a policy of insurance or is not a self-insurer at the time a worker employed in the execution of the work receives an injury, liable to pay any compensation under this Act which the principal would have been liable to pay if that worker had been immediately employed by the principal.
(2) If compensation is claimed from or proceedings are taken against the principal in respect of any such injury, then, in the application of this Act, reference to the principal shall be substituted for reference to the employer except that the amount of compensation shall be calculated by reference to the earnings of the worker under the employer by whom the worker is immediately employed.
………
(6) This section does not apply in any case where the injury occurred elsewhere than on, in or about premises on which the principal has undertaken to execute the work or which otherwise are under the principal's control or management, but nothing in the foregoing affects the liability of the contractor under any other provision of this Act.
………"
48 In the Answer which was filed on its behalf (BAB 125), Universal denied that it was liable to pay compensation, the grounds upon which that denial was based including the following:
"1. The Third Respondent denies that, in the course of or for the purposes of the Third Respondent's trade or business, it entered into a contract with the First Respondent for the execution by or under the Third Respondent of the whole or any part of work undertaken by the Third Respondent.
………
3. The Third Respondent denies that the injuries which led to the worker's death were sustained by the worker in the execution of work the subject of a contract between the Third Respondent and the First Respondent.
