“15. The strength or quality of a polymer depends on the size of the molecules. This is usually expressed in terms of its molecular weight (Mw) a measure of the quality of a polymer. Molecular weight is a measure of the average length of a polymer chain. The longer the chain the better the mechanical performance, and the better the environmental stress crack performance. This is because the longer the chains, the greater the number of entanglements between chains. This means, in turn, that the force required to break these entanglements increases. This is the fundamental principle of entanglement theory for impact performance of amorphous polymers. 16. In the plastics industry, the quality of a thermoplastic is often expressed in terms of its melt volume rate (“MVR” also known as Melt Flow Index “MFI”). This measures the flow of a molten polymer through an extrusion plastometer under specific temperature and load conditions in accordance with ISO 1133. MVR is a crude measure of molecular weight but one that is used as an industry standard because the test is easy to perform. The lower the MVR of the polycarbonate, the higher the molecular weight. This is because, as mentioned above, a polycarbonate with high molecular weight has a greater number of entanglements between chains and therefore flows more slowly than a polycarbonate with a lower molecular weight. A polycarbonate with a low MVR will be stronger and tougher. A polycarbonate with a high MVR will be weaker and will be brittle. In general terms, a polycarbonate will become brittle if its molecular weight is less than 35,000 grams per mole. 17. A polycarbonate which has a higher MVR will have a lower mechanical strength. In general polycarbonates with MVRs of more than 20-25 are not suitable for the manufacture of products which require mechanical toughness. 18. Many hundreds of thousands of tonnes of polycarbonate are manufactured in the world every year by a small number of leading chemical companies. In general, the lower the MVR the higher the price. This is because extrusion grades (lower MVR) which have higher tolerances and improved mechanical and chemical resistance properties are more expensive to produce and process than injection moulding grades (higher MVRs). 19. There are two major types of polycarbonate sold. Virgin polycarbonate is polycarbonate which has not been altered from the time of original manufacturing to the purchase of the product. This is generally sold by the chemical companies which manufacture it, such as GE and Bayer. The other type of polycarbonate is regrind or reprocessed. This comes from polycarbonate which has already been moulded. This can be either manufacturing waste or end of life product. This polycarbonate is ground into pellets which can then be compounded again with other material and/or additives (both virgin and other regrind pellets) to produce a new product. The moulding and grinding processes degrade the polycarbonate so that reground/reprocessed material will always be of a lower grade than the original virgin material. The precise grade can vary over a very wide range depending on the nature of the original feedstock (that is, the polycarbonate which is reground) and whether or not virgin material is added.”
“34. The MVR was much greater than 12. It was certainly in excess of 40. This, in turn, shows that the polycarbonate had a very low molecular weight. Not every batch of polycarbonate delivered by Anglo has been tested and it is likely that the MVR would vary between batches The Plastics experts’ joint statement at paragraph 7.7 and 7.9 indicated a considerable variation of MVR between 20 and 70. , depending on the exact source of the polycarbonate. However, the test results show a high degree of consistency, showing a molecular weight between 33,000 and 37,000 grams/mole suggesting, in turn, an MVR in the range in excess of 60. In contrast, the Sylex polycarbonate has a molecular weight in the range of 45,000 to 48,000 grams/mole suggesting, in turn, an MVR in the range of 10-14.”
“25. I was extremely surprised to see the molecular weight of 33,000 grams/mole. This is a very low figure for a polycarbonate and is, indeed, the lowest polycarbonate molecular weight that I have ever seen in nearly 20 years in the plastics industry. Research had indicated that a molecular weight of 35,000 grams/mole is a "transition point", below which the strength of the polycarbonate decays dramatically (see Gardner and Martin, Appendix 5). I do not think that polycarbonate of that molecular weight has any commercial application.”
“It was agreed that materials with low molecular weights (below 34-35,000) would have substantially reduced lifetimes because of their inability to sustain damage and their accelerated thermal degradation in service.”
“if the supplier changed [Rowan] had to stick to the specification required for the mouldings”
“What prompted me to raise the issue [of an alternative supplier] with Gary was the fact that Cotswold Compounds had begun to alter the prices of their polycarbonate. We were concerned about this and were keen to explore the possibility of using alternative suppliers.”
“it was inconvenient for Rowan to continue purchasing Sylex compound from Cotswold as Rowan only purchased Sylex for Trac. Anglo Polymers were a bigger compound supplier to Rowan and it was easier to buy from them”
“Once things settle down at bit I would suggest we need to work this as a priority – the improvement in margins could be substantial when you compare£1,535 per tonne against£1,200 per tonne.”
“Q. You must have been delighted with this huge price reduction. A. Fantastic. Q. You must have mentioned it to Mr Cochrane immediately? A. No. Q. He was completely au fait with you taking the profit? A. Yes. … Q. Why did you not say to him: Gary, this is fantastic news, I found somebody who can do the same spec for 20 per cent less? A. Because the price was none of his business. Q. Exactly so, Mr Kelly. It is not a matter you ever discussed with him, is it? A. No.”
“Once things settle down a bit I would suggest we need to work on this as a priority - the improvement in margins could be substantial when you compare£1,535 per tonne against£1,200 per tonne!!”
“What melt flow do we need?”
“Please see attached specs on a reprocessed black polycarbonate from Anglo Polymers. What do you think??”
“Q. Your purpose in these discussions with Anglo was purely to serve Rowan’s own commercial interest, was it not? A. Yes, definitely. We were pursuing the£1,200 a tonne price for sure. Q. You were not trying to benefit Trac. You were trying to benefit yourselves. I am not criticising you for that. A. Yes ….. Q. As far as you were aware, did Trac know anything about Anglo at all? A. As far as I was aware? At this stage [i.e. March 2000] I do not think that Gary was aware of Anglo no.”
“Please supply details of specification, technical information, pricing and delivery for the above material as per technical information sheet attached.”
"Quoted on UV stabilised PC from Regent, black, clear and grey."
"Guys, just a quick update on Trac for you. From all accounts the material we are getting in from Cotswold Compounds is reprocessed. This really does open the door on us trying other reprocessed materials from other suppliers. Gary at Trac is okay with us using other suppliers as long as the quality is okay on the parts. Once things settle down a bit, I suggest we need to work on this as a priority. The improvement in margins could be substantial when you compare£1,535 per tonne against£1,200 per tonne."
“2.2 A component specification sheet is completed by the production manager or his deputy detailing the approved supplier, part number and description, any mechanical/technical information, supplier specification sheets are also attached. 2.3 All materials and components shall be checked for • Quality – against purchase order • Specification – Against purchaser order and the specification sheet if applicable, or approved sample”
“(1) Electrical equipment shall be – 1. safe 2. constructed in accordance with principles generally accepted within the member States as constituting goods engineering practice in relation to safety matters and in particular shall be designed and constructed to ensure that it is safe when connected to the electricity supply system by providing a level of protection against electrical shock which relies on a combination of insulation and the protective earthing conductor contained within the electricity supply system or which achieves that level of protection by other means; and 3. in conformity with the principal elements of the safety objectives for electrical equipment set out in Schedule 3 to these Regulations.”
“On the occasions when Anglo supplied polycarbonate with a MVR in excess of 12, that fact would have been plain and obvious for Rowan, Moss or their subcontractors to see when beginning to process it. Rowan and Moss must therefore have continued to purchase and use the material supplied by Anglo when it was plain and obvious that its MVR exceeded 12. The chain of causation between any breach of contract by Anglo and any loss suffered by Rowan and Moss was thereby broken.”
“8.3 AC [Clements], IW [Wadsworth], JG [Goff]:- were in agreement that Rowan’s process was poorly controlled. Analytical studies of housing material, i.e. molecular weights (MVR), showed dramatic differences, which would have significantly affected the behaviour of the material when being processed. IC [Cleathero] is of the opinion that the consistency of the material is a factor in the control of the process, and that this may have contributed to the apparent variation. IC is of the opinion that it is therefore not possible to conclude that the moulding process itself was poorly controlled. “8.4 IC:-believed that, given the procedures operated by Rowan, the infrequent running of each tool and the nature of the mouldings, it is possible that the operatives did not notice differences in the two materials. He did agree that if the company had recorded operating conditions for the products then differences may have been apparent. “8.5 Injection-moulding trials by JG showed significant differences in material processing history. JG, IW and AC were of the opinion that such differences in material properties should have been clearly apparent to any injection moulding technician and that such differences in material properties would have undoubtedly dictated a significant change in operating conditions in order to process these materials. It was envisaged by them that the injection-moulding technician must have changed operating conditions for these materials many times and should have reported this as a material quality issue.”
“It was also agreed by JG, IW and AC that it was surprising that Rowan exceeded its own tolerances and then knowingly supplied out-of-spec product to Trac without informing either Trac that the product was out of spec or without informing Anglo/Plastribution that the material may be causing this problem.”
“(1)(a) How many claimable returns were made between July 2000 and31 March 2004 ?”
“(1)(b) What adjustment should be made for the “underlying rate of returns”?”
“Because the customer would have had a very substantive amount of use out of the product and it would be far, far less likely that any credit or replacement would be required.” “It is my suggestion, that I think it is a logical period, after which any credit is inappropriate. Five years is a long time for the product. It is well into the age of the product and it is becoming increasingly unlikely that a credit would be expected. The propensity to expect a credit from the customer will decline over time.”
“I looked at the trend lines for returns, starting in various months, and I felt that there was no discernible trend, either up or down, in returns in that period. And also, based on all the information I know about the returns and the problems that may well still be out there and may well come back … I felt that the reasonable approach was to take a static rate of return into the future”
“Basically, what has been done here is to take what I would loosely call a top down approach; in other words, taking the overall information which is put before us in terms of the budgets for the company, taking one figure for turnover which encompasses the whole range of products, taking an average gross margin and taking an analysis of costs; and the objective is to produce a loss of profits calculation for Trac. “In my own view, that is wrong on two accounts. First of all – it has been touched on before – it should be a loss of contribution, a loss of margin. And secondly, it should be the impact of the plastics problem, wherever that might be in the company. To do that, if you do not have a satisfactory top down ability, in other words looking at the overall results of the company, looking at the analysis of the company, looking at the breakdown of results, then you are forced to a bottom up approach. A bottom up approach means you look to the records the company has – it does have enough records – to look at the customers, the clients that have been affected, or may be affected, to do an overall exercise of a control group, if you can find one, of the so-called unaffected products, and do a more sophisticated review from that perspective. “In my view, given the state of the budgets, in terms of their lack of support, in terms of their lack of analysis, meant that was the proper way to do this. I indicate my concerns in my report.”
“what I have looked at is the actual costs that have been incurred by this business to date; and it is my opinion that that is one of the reasons why forecasts have not been achieved; and the balance of the variance from forecast, I have seen no other evidence other than to suggest that it has been caused by issues with the plastics. “At that level of past cost, my calculation is as – is set out here. So you look at the variance to forecast and you say: right, okay, the variance relates to costs that have actually been incurred that would not have been ordinarily, and the balance is issues to do with the fact that the business has been disrupted. So my calculations, at that point, are based on the actual past costs that I have calculated. If there were small variances around the past costs that I have calculated then, yes, my calculations would arithmetically work like this. But if, for some reason, the claim for past costs was reduced by half or whatever, 10-75 per cent, I would not alter my claim for – calculation of the claim for loss of profits. “And in the joint statement we set out ranges of losses and my past loss, in relation to returns range, was from quite a low level, based on the number – because we agreed that is how we would do it, to a higher level. But I did not alter the past loss of profits. … “But round a small variance I probably would alter the figures, yes, arithmetically.”
“It offends public policy in two respects. First it assumes that someone who had committed fraud in the past would continue to do so in future; ignoring the possibilities of repentance and detection. Secondly it treats the proceeds of illegally concealed earnings as providing a valid head of recovery by way of damages …”
“the pounds of which he spoke were those derived from wages honestly earned or income honestly received.”
“If a plaintiff comes to court and asserts as part of her case that she would have committed criminal acts and bases her claim upon such an assertion, she cannot recover in a court of law on that basis. Here she has claimed a loss of dependency on the basis that the deceased would have paid sums to her which he had to her knowledge obtained fraudulently from the benefits office.” and at E: “This principle provides an additional reason why the plaintiff’s argument that she could claim a loss of dependency based upon the loss of a combination of undeclared part-time earnings and fraudulent payments must fail.”
“I, for one, protest against arguing too strongly upon public policy; - it is a very unruly horse, and when once you get astride it you never know where it will carry you. It may lead you from the sound law. It is never argued at all but when other points fail.”
“If a plaintiff comes to court and asserts as part of her case that she would have committed criminal acts and bases her claim on such an assertion she cannot recover in a court of law on that basis.”
“In my judgment the reasoning in Duller v South East Lincs Engineers, which was neither cited nor referred to in the judgement in the Hunter v Butler, is plainly correct. In a non-dependence case if the claimant derives income from a lawful source even though there may be a collateral illegality in the performance of the contract (Le Bagge v Buses; St John Shipping Corporation v Joseph Rank Ltd [1957 1 QB 267) he is entitled to rely on the loss of that source of income to found a claim although it may be necessary to make some financial adjustment for unpaid tax and national insurance. If the source of the claimant’s income is itself unlawful, for example the proceeds of crime, then the same consideration would apply as in Hunter v Butler, where the plaintiff was equally guilty with her husband of a fraud on the benefit system.”
“[W]here a claimant has to rely upon his or her own unlawful act in order to establish the whole or part of his or her claim the claim will fail either wholly or in part.”
“In short I accept Mr Davies’s submission that the appellant’s deception struck at the root of the contract under which he earned remuneration and that it would have done so in the future. In this regard it is I think important to note that this will only be the case where the claimant has deliberately deceived his employers; mere failure to disclose the true facts to an employer is not enough.”
