The facts of the offence
29To a large extent, the objective facts were not in dispute. Some factual conclusions reached by her Honour, to which I will come, were, and remain, in dispute. The undisputed facts are as follows.
30At about 5.00pm on 21 July 2009 the appellant inserted a steel rod into the volume meter of one of the pumps ("pump 1") at the Central Pump Site. His purpose in doing so was to interfere with the operation of the meter, and prevent it recording the volume of any water pumped from the Murrumbidgee. The insertion of the steel rod constituted the offence to which the appellant pleaded guilty. He then turned on the pump. Water was pumped from the Murrumbidgee into the main channel. The taking of the water was not an element of the offence. The "hour meter" on pump 1 was, at that time, not operational. Accordingly, there was no metered record of the volume of water taken at that time. The appellant had previously manufactured the steel rod, which was thereafter left at the pump site. He had used it for the same purpose on at least one previous occasion.
31After doing this, the appellant left the area. He did not return until about 10.00am the following morning.
32The appellant knew that it would take some time for the pumped water to flow along the main channel and into the house dam. That was why he did not return to the Central Pump Site until about 10.00am the following morning. It was, no doubt, the continued operation of the pump over that time that caused the respondent to charge a "continuing offence" within the meaning of s 363B of the WM Act. (However, as no additional penalty was imposed, it is not necessary to consider this further.)
33On the morning of 22 July 2009, at about 10.00am, two officers of the State Water Corporation ("State Water") (Brett Richardson and Phillip Dempsey) attended the Central Pump Site on Ravensworth. The evidence does not disclose their purpose in doing so. They observed that pump 1 was operating, and feeding water from the Murrumbidgee into the main channel, and that the meter was not operating. It was shortly thereafter that the appellant arrived at the Central Pump Site. He had a conversation with the two officers, who told him that the volume meter was not operating. (The hour meter was also not operating, but that is not material to the present proceedings.) The appellant turned off pump 1, and turned on a second pump, on which a volume meter was operating. The pump was therefore operating continuously without the meter functioning, over a period of about 17 hours. The appellant estimated that in that time it would have extracted 30-40 megalitres of water.
The appellant's motivation in tampering with the meter: relevant evidence
34The appellant's purpose in pumping the water was one of the principal matters in dispute. His evidence was that his purpose was to feed water into the house dam, via the main channel, to be used for domestic purposes in accordance with his "basic landholder rights" conferred by s 52. There was no statutory obligation to meter water taken for that purpose.
Events following the commission of the offence
35The State Water officers then examined the meter on pump 1, and discovered the steel rod. They contacted compliance officers from the NSW Office of Water ("NOW"). (I use the terminology that appears in the evidence. It is likely that State Water and NOW are the same entity.) Two compliance officers from NOW (Greg Delmenico and Kerry Hehir) attended in the early afternoon. They, too, observed the steel rod in the meter of pump 1. They contacted the appellant by telephone and he joined them at the Central Pump Site shortly thereafter. They had a conversation with him in which they introduced themselves and told him that they were present to investigate an allegation about interference with the water meter. The conversation which ensued was electronically recorded. A transcript of the conversation was in evidence. The following extracts from the conversation, as recorded in the transcript, are material to the issues raised in the appeal:
"Q15 Ron, I guess - what can you tell us about the matter of the meter not working?
A Err there was either the rod there, isn't it?
...
Q17 So you agree that the rod was interfering with the meter?
A It seems to be.
Q18 Okay. Do you know anything about that rod being up the pipe?
A Well, the rod's up the pipe anyhow.
Q19 Okay. You don't know who placed it there?
A No, the rod's up the pipe though.
...
Q22 You agree it appeared to be interfering with the meter working?
A The (indistinct) seems to be that way.
Q23 Yeah, okay. Did you put the rod up the pipe, Ron?
A I'm not too sure.
Q24 Okay, so you're not sure whether you put it up there?
A I don't know whether I was there when that - when it happened or not ... could have been.
...
Q26 Okay. Who else could have maybe put the rod up the pipe?
A It could have been the employee.
Q27 What's the employee's name?
A I couldn't tell you that now.
Q28 You don't know --
A No, just say - just say meself, you put my name down there.
Q29 So you knew the pipe rod was going up the pipe.
A Yeah.
Q30 -- to interfere with the meter?
A Mm.
Q31 Why did you authorise your employee to do that?
A I don't know. It doesn't matter, it's done.
Q32 Okay. What was the water being used (sic), Ron?
A To fill the house dam at the moment.
Q33 Right, so how long had the rod been up the pipe?
A Yesterday, last night.
Q34 Last night, about what time?
A At - I don't know, 5 o'clock or something like that.
...
Q39 Okay, alright. So apart from putting the rod up the pipe interfering with the meter last night at 5 o'clock to fill a house dam --
A Mm mm
Q40 -- have you ever done that before?
A Done it before?
Q41 Yeah.
A It probably has been done once or twice before.
Q42 Okay. With your knowledge?
A Sometimes without my knowledge.
Q43 So an employee?
A Once upon a time the water - I didn't understand it not long ago.
Q44 You didn't understand what exactly?
A And then it might have happened once or twice.
Q45 Alright, so - but you weren't aware of it --
A Mm mm.
Q46 -- those other times? Okay. Has the rod ever been up the pipe interfering with the meter with water being pumped into one of the irrigation storages or applied to any crops?
A Sometimes when it goes to the house dam, it does goes (sic) past there and goes into the crop sometimes yes
Q47 Okay. Could you --
A It wouldn't have been - it hadn't been done too often.
Q48 Could you estimate volumes?
A No.
...
Q65 I guess, Ron, did you know it was wrong to put the rod up the pipe to interfere with the meter?
A Yeah, I suppose I did, yeah.
..."
In cross-examination the appellant explained his answer to question 46 in the following way:
"No, what I meant there when you fill up the channel near the house dam at the school bus stop you fill - usually we keep the channel always full of water so when we want to fill up the house dam we can quickly and sometimes there you're still - if you start irrigating you irrigate too but you don't let the channel drop down, you try and keep the head up in the channel, at all times because not only does it just feed the water to the house dam it also feeds our livestock on the other side of the road."
36On 20 November 2009 Mr Craig Jones (also a compliance officer with NOW) and Mr Hehir attended at Ravensworth, by arrangement, for a further interview with the appellant. A transcript of that interview was also in evidence. The following questions and answers, as recorded, are relevant:
"Q260 Yes. Do you agree you said you used the number 1 Caterpillar Diesel Pump?
A Yes.
Q261 When did you start that pump?
A The day before.
Q262 So that would be 21 July?
A Yes.
Q263 Do you know what time you started it?
A I'm not too sure. It was late in the afternoon.
Q264 Who did start the pump?
A I did.
Q265 Was anyone with you?
A No.
Q266 Did you check the water meter after you started the pump?
A No.
Q267 Where were you pumping water to?
A In the channel.
Q268 Once it had gone into the channel, where did you intend the water to go?
A In the house dam.
Q269 How much water did you want to deliver to the house dam?
A I had to fill the channel up first but the house dam didn't take much.
Q270 How much does it take to fill that channel?
A It'd take easy 100 megs. It might even be more, 150 megs maybe.
Q271 Was there any water in the channel at the time?
A There was some; not a lot. Very little on this end; virtually none. Only puddle - only puddle holes sort of thing.
Q272 So in general terms would you describe the channel as wet or dry?
A Dry. It had some on the bottom and that was all.
...
Q276 So what do you think the capacity of the house dam is?
A It might only be a couple of megs, two or three megs.
Q277 To fill the house dam on this, what's pretty well dry channel, how many megs do you think you'd have to pump to get it down there?
A I'd say you'd need probably 100, 150 megs altogether.
Q278 Yes. The water that was going to the house tank, what was the intended use of that water?
A It was going for the houses.
Q279 When you say for the houses, do you agree it was for general domestic use in those houses?
A Mm.
Q280 Such as drinking?
A Mm.
Q281 Washing?
A Mm.
Q282 Showering?
A Mm.
Q283 And garden, domestic garden watering?
A Yes.
Q284 Once the house tank was full, where would water go to after that if it continued to be pumped?
A Most times we keep it in the channel but then after that it can go to irrigation. But most times it just sits in the channel. We usually keep the channel full so that if you've got to top the dam up you can real quick and you can just open the gate up again and it doesn't take much to fill it up. But this particular time the channel was right empty.
Q285 Whilst you were filling the house tank, was anyone monitoring where the water was going?
A No, but because it wasn't - it had only just got there. It was only just starting to get there.
...
Q289 Do you agree earlier that I said the NSW Office of Water compliance officers located an object up the outlet pump of the number 1 river pump on 22 July?
A Yes.
Q290 Have you seen that object before?
A Yes.
Q291 What would you call it?
A A steel rod. A stick. A steel rod.
Q292 Can you tell me how the steel rod got into the pump outlet?
A Yeah, I put it there.
Q293 When did you put it there?
A The day before when I started the pump.
Q294 Do you know what time it would have been?
A Late in the afternoon.
Q295 What was your intention in putting the rod up there?
A I was trying to fill the channel up so that I can get some water for my house dam because it was empty
...
Q300 After you inserted the rod into the pipe, what did you do?
A Started the pump.
Q301 Did you check the meter after you started the pump?
A No.
Q302 Who manufactured the steel rod?
A I did.
Q303 When did you make it?
A Can't remember. Before (indistinct).
Q304 How did you make it?
A In the workshop.
Q305 What's it made out of?
A Steel.
...
Q307 Where did you normally keep the steel rod?
A Just there. And it was just there at the pump site.
...
Q311 Have you used that steel rod on any previous occasions?
A I might have used it once before.
...
Q316 Why did you want the meter to stop?
A So I can fill my house dam up because the channel's low.
Q317 You could have filled the house dam though with the meter operating.
A Mm.
Q318 So why did you want the meter stopped?
A I just did. I did something I shouldn't have done. I know that.
Q319 Do you agree by stopping the meter working properly that your account probably wouldn't be debited for the water that you extracted?
A Yes.
Q320 Was it your intention not to be debited that water?
A Yes.
..."
There followed a number of questions and answers it is not necessary here to record. Some time later the following question was asked and answer given:
"Q408 Sorry, just looking at how much water was in the channel and whether it reached the house dam or not, could you make a reliable estimate of how much water you'd pumped from how much water was in the channel or in that house dam?
A No, not really because the water had only just got to the house dam. At that time it had only just got to the - not to the house dam, it only got to the end of the school bus stop where the water stops. It only just got there from - and we also had another pump going at the same time so the water was just there. It depends. I didn't go along the channel to see where it actually was. I just know the next morning the channel was chock a block full and the house dam was full.
..."
37In his affidavit, the appellant explained why he had disabled the meter. He said that, on the afternoon of 21 July, he noticed that the house dam was becoming low. He intended to release some water from the main channel to fill the dam, but found that there was insufficient water in the channel to allow gravitational feeding into the house dam. For this to occur, it was necessary to pump water from the Central Pump Station into the channel. To do this, he wished to make use of his basic landholder's right under s 52 of the WM Act to take unmetered water for domestic or stock purposes. Access to water from the Murrumbidgee under that right did not require metering.
38Given the distance between the Central Pump Station and the house dam (22 kilometres) it typically takes about two days for water to travel from the Central Pump Site to the house dam. It takes another two days for the water to be filtered through the water treatment plant. For this reason, the appellant said, his usual practice was to maintain a high level of water in the main channel. Why this was not the case in July 2009 was not explained, but the appellant said that at "this particular time the channel was right empty".
39In paragraphs 49 and 50 of his affidavit the appellant said:
"49 As I was intending to use the water to fill up the House Dam, and I understood that we were entitled to use Domestic and Stock Water for that purpose without it being ordered or metered, I did not want to use water allocated to the General Security Licence that could otherwise be used to irrigate commercial crops on Central Farm. That was a particular concern to me around this time because I was aware that there was a water shortage in the Murrumbidgee Regulated River Water Source.
50 For that reason, at about 5pm on 21 July 2009, I placed a rod in the pipe of the water flow meter for the pump known as "pump 1" at the Central Pump Site so that the water that was pumped for the purposes of the House Dam would not be debited to our water account. I then turned on pump 1."
40He said that when he returned to the Central Pump Site at 10am on 22 July (when he encountered Messrs Richardson and Dempsey) he did so with the intention of turning off pump 1 and turning on another (metered) pump. This would mean that the balance of water taken would be recorded on the meter of that pump.
The evidence of the appellant
41The appellant's answers in cross-examination are not easy to interpret. For example, he was asked about his answer to question 46 in the first interview. The following questions and answers appear in the transcript of evidence:
"Q I take you to question 46 [of the first interview, extracted above], do you accept you were asked this question, 'those other times, okay, has the rod ever been up the pipe interfering with the meter with water being pumped into one of the irrigations (sic) storages or applied to any [crops]?' Answer 'Sometimes when it goes to the house dam, it goes past there and goes into the crop sometimes, yes'. Do you accept that was the answer you gave in question 46?
A Yes.
Q So you told the person asking the question that you'd used the rod sometimes which means more than once, doesn't it?
A No, what I meant there when you fill up the channel near the house dam at the school bus stop you fill - usually we keep the channel always full of water so when we want to fill up the house dam we can quickly and sometimes there you're still - if you start irrigating you irrigate too but you don't let the channel drop down, you try and keep the head up in the channel at all times because not only does it just feed the water to the house dam it also feeds our livestock on the other side of the road.
...
Q In any event lets look at the answer, 'and goes into the crop sometimes', can you use the red pen and mark with whatever shape is appropriate, a circle, a square, where you're referring to 'it sometimes went into the crop'?
A What I'm trying to say there - all the time what I tried to say there is it's a double edged sword there. We fill the channel up and when the channel's full and that's where we keep it full so we've got our stock order for the other side of the road and we also keep it full so we can fill the house dam at any time - when you want to find out your house dam's low you can go and open the gate and fill it and then sometimes there if you're irrigating your crops later on when you want to irrigate your crops, well, what pallets of water - I've been to the dam and there's two lots of water in there sort of thing so when you want to irrigate your crops you still keep the channel at the same height. It's a bit hard question to answer, sir.
...
Q So on one occasion at least previously when you've used the rod the water was used to irrigate crops, wasn't it?
A No.
...
Q Having been taken to those answers didn't you say previously that on at least one occasion the water extracted after using the rod on the meter had been used to go on the crops?
A All the time I said when we filled up the channel all the time - we try and keep the channel full all the time for your livestock on the other side of the road and your Pethers (?) block and also fill our house dam up. At the same time if you can irrigate on the other side, well sometimes the water - you always keep that channel full and water can still go past onto the other side.
...
Q So once the house dam is filled the water left in the channel, some of that goes to irrigating crops, doesn't it?
A It's only when you start pumping to go to irrigate you still keep the channel full, the channel is still full.
Q So some of the water used to fill the house dam once you recommence pumping, that existing water would then used to be irrigate that was in the channel?
A No, it'll still be equivalent because you've still got the channel full and the water runs over the top, over the other side, so you kept the channel full.
Q Can you explain that running over the top?
A Well, or you can keep the channel at a certain height and while you're there you just regulate your pipes at the other end, at the gate, so as X amount of water is coming down you keep the channel height exactly the same, you don't drop the level so you keep the same volume of water in that channel at all times so you don't drop the volume of water that's in that channel.
Q So are you saying none of the water already in the channel that's moved along?
A It's only got new water coming from the pump site, new water comes in and move over, it might mix up but the channel is always still full.
Q So some of the water existing in the channel in the way you've described would then be used to irrigate?
A No, it depends. You can't tell which water it was that was in there. You use a common channel.
...
Q And if you hadn't been detected on 22 July 2009 the plan was to fill your channel for the whole 22 kilometres?
A That's why I went and swapped over and put the other motor on and I also had - there was two other pumps pumping into that channel that day. There was also one pump in storm water.
Q So as I understand it you say about 10am on 22 July you turned up to stop the pump pumping to which the rod was connected?
A Yes.
Q If all you wanted to do was fill the house dam for two to three megalitres you could have done that, that is, stock [sic - ? stop] the rod being around the meter on the afternoon or evening of 21 July 2009 so that only about two to three megalitres went?
A No.
Q Why not?
A Because you had to build the channel head level up high enough to get the water to gravitate into the house dam."
42In oral evidence the appellant agreed that that part of his answer to question 295 in the second interview, that the house dam had been empty, was incorrect. He said that the house dam "might have been a third full".
43Throughout his oral evidence, the appellant maintained that his intention in disabling the meter was to facilitate the exercise of his rights under s 52 of the WM Act. He did not wish his entitlement under WAL 8309 to be debited with water to which he was entitled to have free access.
44The appellant was extensively cross-examined. He was asked about the apparent evasiveness in his responses to Mr Delmenico in the initial interview. He said this was:
"... because I was just told there was an offence committed and I was devastated really and I've got the officers there and I'm not too sure what you should say or do then."
Asked if he panicked, he said:
"I'm not too sure, I didn't have any representation or anything there."
45Concerning his intention in disabling the meter, what was, in effect, put to the appellant in cross-examination was that his intention was to fill the main channel with unmetered water taken pursuant to his s 52 rights, but, consistently with his answers to question 284 in the second interview, and consistently with past practice, after filling the house dam, to use the water remaining in the channel to irrigate crops. This would be an impermissible use of water taken under s 52. It was in response to these questions that the appellant gave the answers recorded at para [41] above. It was never clearly or directly put to the appellant that his motive in disabling the meter was financial gain, nor that his intention was to use the unmetered water (or some of it) to irrigate crops and to avoid paying for that water.
46As I have noted, the appellant's answers are not easy to interpret. It seems to me that what he was saying was that he intended to exercise his s 52 rights to provide water to the house dam. This entailed taking more water than the 2 to 3 megalitres that would fill that dam, because of the need to create sufficient force for the water to "gravitate" to the dam. (There was no evidence as to the gradient of the main channel, but there was no challenge to his evidence in this respect.) The consequence was that, after the house dam filled, there remained some unmetered (s 52) water in the main channel. By reason of s 52(1)(c) that water could not be used for any purpose other than domestic or stock requirements. However, having taken sufficient water to fill the house dam, the appellant then intended to switch pumps, in order to obtain metered water that could be used for irrigation purposes. The inevitable result would be a mingling of unmetered and metered water. Some of the (unmetered) water pumped by pump 1 was at least available for irrigation purposes (whether actually used for that purpose or not). What, it seems to me, the appellant was saying was that, to the extent that this occurred, he made good so much of the unmetered (s 52) water used for irrigation by replacing it with metered water.
47It is reasonably clear that the appellant could make no precise assessment of the quantity of unmetered water taken via pump 1, and that taken via a metered pump. That, however, is a consequence of a number of factors, including that the main channel had to be used to funnel water for both s 52 purposes, and for irrigation and any other non-s 52 purpose.
48Cross-examination of the appellant established that he had, prior to the offence, planted a considerable wheat crop which it was hoped would eventually realise "some millions of dollars". He had also (as deposed in his affidavit) placed an order for 300 megalitres of water. That water had not, at the time of the offence, been made available. What is not clear is when it would have become available and when the appellant required it for the purpose of the wheat crop.
