Day 190: The revival of Dr. Burns' expert testimony

The noted American physician and tobacco researcher, David M. Burns, might have found his ears, um, burning this morning as the Montreal Tobacco Trials suspended the hearing of witnesses to debate a motion that would prevent him from testifying at this trial.

Or perhaps he is used to it -- Dr. Burns' participation at this trial has been debated before.

Those with long memories might recall that two years ago the federal government filed an expert report they had commissioned from this prolific researcher - "The evolution of public health recommendations regarding low tar and nicotine cigarettes." 

Much of the report focused on Monograph 13, the watershed report of the National Cancer Institute that was issued in 2001. It put to rest the idea that low-tar cigarettes had any health benefit and Dr. David Burns was the senior scientific editor of the report.

But since then, the status of Dr. Burns and his report were changed more than once:
* In April 2012, the report was challenged by the tobacco companies, who felt that it went beyond the scope of what should be included in the government's defence.
* On May 1, 2012, Justice Riordan agreed in part, and ruled that much of the report be excluded. (Specifically, matters related to low-tar cigarettes, the development of the 1981 Surgeon General's report and the NCIC Monograph 13. He said those questions were not relevant to the government's case).
* On November 13, 2012, the Court of Appeal turned down the request of the federal government for this issue to be reconsidered by the higher court. (The sting of that decision was doubtless lessened by the decision the same court made the following day to liberate the government from the case altogether).

A year later, the plaintiffs have dusted off the report. In recent weeks, they apparently informed the defendants of their intention to ask Mr. Burns to present it and his expertise in support of their case during the "counter proof". What triggered their interest was the testimony this September by Imperial Tobacco's expert witness in compensation - Mr. Michael Dixon. (Mr. Dixon is a scientist who has been employed and contracted by British American Tobacco).

Mr. Dixon challenged
this finding from
Monograph 13
Although Mr. Dixon had made no mention of Monograph 13 in his report, it evolved as a focus of his oral testimony. There was no mistaking his disdain for this scientific consensus against low-tar cigarettes (which Mr. Dixon still believes are a safer option for smokers). He went so far as to say that the authors had improperly calculated the amount of compensation, and offered his own corrections to their data. (Exhibit 40346.221 B)

"Too late and too little value to the trial"

The tobacco companies appeared united this morning in their request to Justice Riordan to exclude Dr. Burns from this trial.

Simon Potter led their argument that he should not be permitted to defend Monograph 13 against Mr. Dixon's comments and re-interpretation. The gist of his argument was that the plaintiffs had missed the boat, and shouldn't be granted a late-boarding pass.

He said it was the plaintiffs' own fault that they had not called the witness earlier -- and that the need to do so should have been apparent from a number of other references to the Monograph. "They were expected to make proof on their issue in their case in chief" but instead had "decided to lie in the weeds on Monograph 13 and wait to see how it panned out."  

To let Mr. Burns testify would be to allow the plaintiffs to "split their proof," and to get "two kicks at the can."  Moreover, the Monograph was not relevant to Canada - as it was "apologia of how American governments made a mistake by encouraging smokers to go down tar." 

(Mr. Potter's argument this morning was instructive in many ways -- I appear to have sat through the same trial and come out with quite different impressions of what has been said. Apparently, when testifying on behalf of the federal health ministry, Mr. Denis Choinière agreed that low-tar cigarettes were a "net public health benefit." How did that slip by me!?)

It's been a while since there has been this kind of procedural wrangle put to Justice Riordan, and he seemed to be enjoying the moment even as he was clearly not enjoying Mr. Potter's version of events. "I am not sure you are characterizing it correctly," Justice Riordan said, and then gave a brief summary of Mr. Dixon's objections with the Monograph and the ways in which it was indeed a new development in the trial and one that had happened after the plaintiffs proof had closed.

He went so far as to offer a hint about how he is receiving the contradictory testimony about compensation.  "I have thought about this. I am not sure what the relevance is whether compensation is complete or partial. Everyone agrees that there was compensation to some degree –whether it was 100% or 85% or 50% ?? -- I don’t see that there is much difference at this point."

Ms. Suzanne Côté and Mr. Francois Grondin thus had a clear idea that Justice Riordan was not likely to support their motion even before they had a moment to make their pitch. Ms. Côté pointed out that Mr. Dixon's role was to counter the testimony of Mr. André Castonguay. Did the judge want to start another cycle of proof and counter proof?  Mr. Grondin focused on the plaintiffs' burden of proof and their responsibility to have met this burden earlier in the trial.

They did not seem to take much comfort from Justice Riordan's comments that they might themselves need additional testimony to be provided. The judge pointed out that the industry's expert witnesses might contradict each other. To some extent, he said, this is what the trial was dealing with. (Monograph 13 was introduced as a result of the report of JTI-Macdonald's historian, Mr. Perrins, but was subsequently attacked by Imperial Tobacco's expert).

Ultimately, the question was not resolved today. Justice Riordan said he would not allow Dr. Burns' first report to be filed, but would allow the plaintiffs to seek a new report on the narrow issue of  reply to Mr. Dixon. At the same time, the companies could prepare for a joint-witness to respond. Until then, he would  "suspend the motion for the moment."

After a few minore housekeeping issues, the trial adjourned at noon.

The road ahead

Ah! more witnesses are falling off the list. Travel plans were given as the reasons that two scientists who worked for or with the federal government -- Mr. Pandeya and Mr. Rickert -- will now likely not be testifying. (But might it not also be that after they met with the company's lawyers their testimony was no longer desired?)

Next week, the final two former government employees will testify. Mr. Brian Zilkey and Mr. Bert Liston. The following week -- the last before the Christmas break -- will have only two witnesses. CTMC-financed researchers, James Hogg, will testify from Vancouver on December 16 and 17th. The trial will not sit on the 18th. The last witness of the year will be Mr. Robert Robitaille.

Day 17 - Questions, Answers, Pleadings, Decisions

The one-time vice president of marketing for Imperial Tobacco, Anthony Kalhok, was again on the stand when the trial of the Montreal tobacco class actions resumed this Tuesday morning.

In answer to Justice Riordan's jovial "how are you, sir?" as the session began, Mr. Kalhok allowed that he felt "perked up" by a weekend of physical exercise.

It would have taken a stalwart temperament to maintain any feeling of perkiness over the next few hours, as plaintiff lawyer Bruce Johnston took the witness through a series of focused and relentless questions about the marketing strategies of Imperial Tobacco during his tenure there.

Young smokers - a major opportunity group

Of the day's rich testimony, some of the most memorable sections involved the company's approach to young smokers. 

Mr. Johnston pushed Mr. Kalhok to explain the constraints under which his department operated with respect to advertising that reached young people. As happened last week, responses were usually framed around a business analysis.

"You set up a context that is the opposite to the context we worked," Mr. Kalhok explained when asked why they did not market to youth. "We did not consciously not target to people under 18, we consciously targeted at people over 18." Why not target smokers?  Well, "there is only so much you can do in an ad."

Mr. Kalhok passed over several opportunities to reveal any qualms Imperial Tobacco might have had about youth smoking.

Mr. Johnston: Aside from the voluntary code was there anything else that determined the decision or policy of imperial tobacco not to market to starters who were of legal age?

Mr. Kalhok:  No.

Mr. Johnston:  The risks or possible addiction, that was not a factor?

Mr. Kalhok:  No.

The second theme to which Mr. Johnston returned was the role of the marketing department in addressing smokers' concerns about their health and the marketing of some cigarettes are safer.

The witness began to look a little less 'perked up' when Mr. Johnston introduced a 1971 marketing plan that had been authored by Mr. Kalhok (Exhibit 151, not yet available).  Mr. Kalhok was given a moment to read over the anlaysis he had provided some 40 years ago

Young smokers represent the major opportunity group for the cigarette industry, we should therefore determine their attitude to smoking and health and how this might change over time.

Mr. Kalhok looked up from the page to his questioner and ruefully admitted that if the document had been brought out earlier, "you wouldn’t have had to ask me about my personal views."

At this point, discussion returned to the first marketing studies conducted by Imperial Tobacco on teenagers. The Kwechansky "Project 16" was cited in other tobacco trials (including the trial of the federal Tobacco Products Control Act and the U.S. federal RICO suit), but this is the first time that the man who had responsibility for the study had been asked to testify on it.

Mr. Johnston read out extracts from the study, repeatedly asking if these had caused concern for the company. Not once did Mr. Kalhok acknowledge any disquiet.

Mr. Johnston:  "Serious efforts to learn to smoke occur between ages 12 and 13 in most cases.”  Was that new information for ITL at that time?

Mr. Kalhok:  Yes

Mr. Johnson:  Did it cause concern?

Mr. Kalhok:  You have to remember these are the claimed behaviours of the 16 and 17 year olds.  It would not have statistical validity.  We were, um, surprised.

Mr. Johnston:  "Like adult smokers, teenage smokers find it very hard to quit, even if they want to do so of their own accord.”  Did that cause concern?

Mr. Kalhok:  No more than coffee, coke, or whatever else. We admit that once you enjoy smoking you like to continue smoking.

Mr. Johnston:  Was it considered at imperial tobacco at that time, that smokers were able to give imperial tobacco or any manufacture an informed adult consent?

Mr. Kalhok:  I don’t understand the question.

Mr. Johnston: Do you understand the concept of informed consent?

Mr. Kalhok:  Probably not.

Mr. Johnston:  Did that information have an influence in a marketing strategy in the direction of exercising extra caution?

Mr. Kalhok. Not really.  As I said, it was not new information.

Mr. Johnson.  "The young do not temper their actions with worries about future consequences. This is partly because they don't really understand them yet, and because to them the future means next week, next month or at most next year. It does not mean in fifty years, or even in five."  Did this information prompt anyone to prompt how this misapprehension could be corrected?

Mr. Kalhok: If I understood your question correctly, we wouldn't tread into that territory to correct that misapprehension between the timing of the pleasure and the timing of a potential risk. The facts were they were far apart. And they perceived them as far apart. There was nothing to correct.

Maintaining the social acceptability of smoking
Mr. Johnston also revisited the issue of  Imperial Tobacco's marketing strategies to respond to health concerns of smoking.  He again questioned Mr. Kalhok on (Exhibit 116) which minuted an observation in 1976 of the marketing, research and public relations staff of the company:

In our normal marketing activities, we are constantly aware of the smoking and health issue. Some of our campaigns are very effective in reinforcing the smoker's choice. The image campaigns being currently run for duMaurier, Peter Jackson and Player's Filter, help to convey three of the basic reasons for smoking. Those reasons are, respectively, social acceptance, personal independence, and the pleasure of smoking.


He introduced minutes of a similar meeting the year before (Exhibit 153), a policy statement by Canadian tobacco companies on the question of tar and other smoke constituents (Exhibit 154- under reserve, but also available on the Legacy site), a memo noting changes to that agreement (Exhibit 155), and a proposed new agreement (Exhibit 156, 156a) where the Canadian companies agree to not "expand on or exploit" health concerns, to permit each other to use the words tar and nicotine, but not to use any  'scary' words like carbon monoxide or gaseous phase.

Other documents introduced but not  yet available were a marketing plan for a new Player's cigarette (Project Pel, Exhibit 157R), a review of the tobacco industry (Exhibit 159).

By mid afternoon, the plaintiff's wound up their examination of Mr. Kalhok.  They took him to a document on which Mr. Descoteaux had been questioned in the opening days of the trial (Exhibit 11), and asked him to identify his handwritten note to his colleague.  "Much of the satisfaction (of smoking) is the effects of nicotine," he had scrawled across Mr. Descoteaux's suggestion that the company should develop cigarettes that would provide the same satisfaction without "enslaving" consumers.  "Would you pay $12 for a 40 oz  of gin if it didn't contain alcohol?"

Judge Riordan's calls. 

1. Smokers are not also passive smokers

Justice Brian Riordan was called on to make two decisions about evidence.

The first was in reply to an objection by the tobacco companies to a question about the company's views on second hand smoke. "Bringing second hand smoke into the picture would be a fundamental change to the nature of the case" said Imperial's lawyer, Craig Lockwood. Despite Bruce Johnston's protest that smokers are also affected by second hand smoke, and that the industry's approach to the science on second hand smoke was relevant to their denial of other science, Justice Riordan shut down the line of questions. "The issue is not relevant to the  (class action) groups."

2. Non-appearing documents about document destruction.

Earlier in the month a press release regarding document destruction (Exhibit 57) had not been provided to the plaintiffs as part of the established exchange of documents. This had raised questions about the consistency of the defendant's document production with an earlier ruling of Justice Riordan.

After establishing that there were other documents in the same category (related to implementation of the document retention policy), Justice Riordan clarified "if there is ambivalence in my previous judgement that is my fault, but that doesn't change the fact that the information is relevant, and it has to be provided.  And it has to be provided in a timely way with witnesses." He called for documents related to "document destruction between 1985 and 1995 and referred to subsequently."

Ms. Glendinning questioned the time-frame of the document net ("AFTER the lawsuit has commenced!?"), but promised to provide details in the coming days about the number of new documents to be produced.

Justice Riordan also clarified that Imperial Tobacco was to give priority in its internal review of documents to those that are intended to be provided to the plaintiffs in the main action, and that delays in providing documents to the plaintiffs that resulted from assigning personnel to documents in the action-in-warranty (the federal government involvement) were not acceptable.

Back to the croquet court

At the end of the day, discussion was resumed on the industry's request to disqualify three of the federal government's four proposed expert witnesses.  Mr. Regnier, speaking on behalf of the federal government, resumed his submission from the previous day and provided a detailed account of where Dr. Farone's testimony was linked to the action in warranty.

Andre Lespérance presented the views of the plaintiffs, and their agreement with the position of the federal government's counsel that the court was operating with common evidence.  The main action and the action in warranty were woven together, he explained, and the division of the cases in examining or cross examining witnesses would be unworkable.  The expert witnesses were pertinent to both cases, he said, because the cases were "mirrors of one another."

In her reply to the opposition to their motion to dismiss the witnesses, Suzanne Coté replied that she disagreed with the view that the two actions were being tried with common evidence. The fact that the cases were being heard and judged concurrently did not mean that they were working on the basis of a signle proof.

She went further to question the relationship of the federal government to the plaintiff's case. "The federal government could contest the principal demand," she pointed out.  (Was she remembering with nostalgia when the federal government had sided with the tobacco companies in opposing certification of class actions on tobacco in British Columbia and Newfoundland after they had been sersved with third party notices?).

Simon Potter apologized for not having provided the whole story to the court about the eventual agreement reached by the tobacco companies and the federal government to allow Dr. Burns to testify in the Tobacco Products Control Act case, even after Justice Chabot had disqualified him.  He did not back down from other positions taken the day before, and repeated his concerns that the expert witnesses were provided too late in the day to be fair to the defendants.

The last word went to Mr. Jean Leclerc (on behalf of the federal government), who urged the judge to read again the Burns report, and to consider that it could not be severed but should be read as a whole.

Tomorrow morning, Mr. Kalhok returns to face cross examination by his former employer's attorneys, and possibly by lawyers representing the federal government.  In the afternoon, the former president and chairman of Imperial Tobacco, Mr. Jean Louis Mercier, will be called to testify.

Day 16 - Expertise not wanted

See note on accessing documents at the end of this post.

As spectator sports go, trial watching does not have the adrenalin rush of the Stanley Cup playoffs (Go! Senators! Go!), although it often calls to mind other sporting matches.

Today's proceedings seemed to have much in common with that sedate summer sport, croquet.  In croquet the object is to be the first to get your ball through the hoops, but the real fun of the sport is in viciously knocking your opponents' balls out of the croquet court, all the while maintaining the appearance of polite gentility.

The first sitting this week was spent discussing the tobacco companies' request to knock three of the federal  government's balls out of the trial court. The industry wants to throw out the expert testimony offered by epidemiologist David Burns, toxicologist Len Ritter and chemist William Farone.

[Unlike fact witnesses who testify on events to which they have a personal connection, expert witnesses provide opinion evidence on matters which go beyond the expected knowledge of ordinary people (even judges). Their credentials are open to challenge.]

Whack!  Dr. Len Ritter


First to take a swing was Suzanne Coté, who works for Osler, Hoskin Harcourt on behalf of Imperial Tobacco. She took aim at the testimony of  Dr. Len Ritter, a Professor Emeritus at the School of Environmental Sciences at the University of Guelph.

In her usual fast pace, she rattled off the criteria that should be required of expert witnesses to the case: pertinence, usefulness for the judge, qualification of the witness and impartiality. She then took successive knocks at Dr. Ritter's work for meeting none of those criteria.

Dr. Ritter's report on industry's knowledge of and research into the harmful properties of smoke did not reflect expert knowledge, she said, and suggested that these were tasks that the judge could perform himself. Justice Riordan laughed when she asked dramatically "where it would take us" if the role of the judge were  usurped in this way.

She also challenged the impartiality of Dr. Ritter's opinion, saying that the documents he selected reflected only one side of the "controversy" about smoking and did not include science that supported the industry's actions.

Whack!  Dr. David Burns


After the morning break, RBH's lawyer Simon Potter picked up the verbal mallet to hit at the expert wtiness testimony of prominent U.S. epidemiologist, Dr. David Burns. In his flamboyant way (did Simon Potter and Rex Murphy attend the same elocution class?) he decried the presentation of this witness as "burdensome, prejudicial, unfair and late".

Mr. Potter claimed that the expert opinion was not pertinent to the government's defence, but was designed to assist the plaintiff's main case. "The action in warranty says that if there were low tar cigarettes on the market it is because the government wanted them there and pushed to have them there," explained Mr. Potter.

"Dr. Burns wants to argue that the  tobacco companies were aware of smokers' compensation and that they designed their cigarettes to facilitate compensation....This is Dr. Burns not defending the action in warranty, it is piling on to the plaintiffs' case."

Mr. Potter claimed that Dr. Burn's recounting of events in the United States were not relevant to the Canadian experience. He pointed to references in the opinion to the U.S. Master Settlement Agreement. "This is Dr. Burns seeking to bring in an enormous piece of American fact," he said. "It is foreign to the true interests of the Attorney General of Canada.”

Mr. Potter referred to the decision of Quebec Justice Chabot to dismiss Dr. Burns in the trial of the 1988 Tobacco Products Control Act, because "Dr. Burns (was) brought forward not to bring his professional opinion, but .. rather to state the professional opinion arrived at by others and to confirm that they are reliable and credible.” He repeated the view earlier offered by Mme. Coté that this was the job of the judge, not an expert witness.

In short, he said "“this report does precious little good."

Whack!  Dr. William Farone


Simon Potter turned his attention to the testimony of the third government witness, the former Philip Morris International chemist, Dr. William Farone. This time the attack was more personal. 

He denounced Dr. Farone as being a man "on a mission” who claims expertise in areas where he does not have it. He presented Dr. Farone as exaggerating his knowledge and contribution.  "He is only a chemist," he said disparagingly, then backtracking slightly "I don’t mean chemist disparagingly. We need chemists in the world.”

Mr. Potter claimed that Dr. Farone had a desire to 'inflame' tobacco issues, and drew attention to uncomplimentary things that had been said about him in other trials. He suggested he had an axe to grind by telling the court that Dr. Farone was not so much a former employee of Philip Morris, but was someone who had been fired by Philip Morris for insubordination.

This is an expert witness who "wants to lard the file." Mr. Potter concluded that Dr. Farone is someone who offers nothing that had not already been provided to the court by the plaintiff's expert witness, Dr. André Castonguay.

A textbook defence


After lunch the government opened its response to the industry's attacks on their witness by presenting a special counsel to the case, Mr. Donald Béchard, the author of a textbook on the admissibility of evidence, Manuel de l'objection.

Mr. Béchard challenged the suggestion by the companies that no special knowledge was necessary to assess scientific reports by reading one sentence from Mr. Ritter's expert report. He pointed out that an ordinary reader might not be able to come to the same conclusion as an expert with subjects of this nature.
“The PAHs found in cigarette smoke are broken down (metabolized) into a variety of compounds by the action of the enzyme aryl hydrocarbon hydroxylase (AHH).”
He questioned the role of the tobacco companies in challenging how the federal government should conduct the case.  "The tobacco companies are trying to say that now that we have trapped you in this case, we are going to tell you how you must defend yourself."  Besides, he pointed out, the use of common evidence as in this case allows for parties to contribute to a common proof.

Mr. Béchard disagreed with the companies that the American orientation of the testimony was a drawback. "The U.S.  experience IS relevant to Canada," he argued. "The government will demonstrate that what happened in the U.S. also happened in Canada."

Cherry Picking


Mr. Jean Leclerc (Gilbert Simard Tremblay) provided a detailed reply on behalf of the federal government to the arguments against Drs. Ritter and Burns. He suggested that the tobacco companies had cherry picked from the expert reports and that doing so had provided a distorted view of the value of those reports to the court. 

He defended the credibility of Drs. Ritter and Burns, reminding the court that Dr. Ritter had testified in the trial of the 1997 Tobacco Act, and that Justice André Denis had found his testimony useful. He pointed out that the science of toxicology does not rest on what produces the toxins  - cigarettes or pesticides - but on the harms these materials cause.

He countered the suggestion that Mr. Potter had left that Burns had been dismissed from the Tobacco Products Control Act Trial by pointing out that eventually Dr. Burns had testified, and that the assessment of Justice Chabot needed to be situated in its historic context, 23 years ago.

On hearing this factual contradiction to the suggestion that Dr. Burns' had not been allowed to testify in a previous Quebec trial, Justice Riordan looked and sounded displeased.  

If it's good enough for Judge Kessler ...


Maurice Regnier was the last to respond to the objections, and he defended the qualifications of Dr. William Farone. He outlined how Dr. Farone's testimony was directly related to the federal government's defence in the action in warranty, as it provided detail on how companies could control the nicotine levels in cigarettes.

"The industry says it is the government's fault to have worked on a tobacco variety that had higher nicotine." Mr. Regnier explained,  "Our case will be to demonstrate that the tobacco plant that grows has very little to do with the nicotine that is produced by a cigarette later."

"The manipulation is not on the part of government, but on the part of the industry."

Mr. Regnier drew attention to the acceptance by U.S. federal judge, Gladys Kessler, of the testimony of Drs. Burn and Farone.  In her 1700 page ruling in 2006, she said had praised the credentials of Dr. Burns:
Based on his superb academic credentials, his extensive experience working on Surgeon General Reports and NCI monographs, his ongoing clinical research, as well as his demeanor and responsiveness to cross-examination, the Court fully credits his testimony.
Likewise, Judge Kessler had accepted the testimony of Dr. Farone:
Dr. William Farone, who worked at Philip Morris for 18 years and was impressive and credible as both a fact and expert witness.
By the end of the sitting, the arguments for and against these there witnesses had not finished. When tomorrow's session opens tomorrow morning, this issue and the testimony of Mr. Anthony Kalhok, former vice president of marketing for Imperial Tobacco will be resumed.

Like a croquet game, the pace is slow and the social niceties are observed. Unlike a croquet game, it will be some time before we will learn whether the industry was successful in knocking these federal balls off the court.
