[I have now provided a brief lay summary of this blogpost.]
The Court of Appeal judgment in British Chiropractic Association v Dr Singh [2010] EWCA Civ 350 is the most complex decision we have so far encountered in this litigation, and it repays careful study.
(Comparing the judgment with the transcript of the hearing is a particularly enlightening exercise. I also note that the Court of Appeal made a point of using Simon Singh’s academic title in its case title.)
The Court of Appeal's decision follows the previous decisions in this case: the astonishingly illiberal ruling of the High Court in May 2009, the terse one paragraph refusal of Simon’s application for permission to appeal in July 2009, and Lord Justice Laws’s wonderful granting of permission to appeal.
(And even a hardened English lawyer must admit it is rather splendid for a Lord Justice Laws to grant permission to appeal to a court headed by a Lord Chief Justice Lord Judge.)
For the reasons I set out below, I think the judgment is significant as it appears that the Court of Appeal has extended the defence of “fair comment” – or “honest opinion” – to all contentions about evidence in any debate (and not only those to relating to science or medicine) “concerned with the establishment of dependable generalisations about cause and effect”.
However, to provide my analysis of this complex judgment, I will have to resort to use two technical terms, well-known to lawyers but not more widely.
The first term is ratio. This means the basis of the court’s decision: the reasoning on which the order made by a court is based.
(The order made here by the Court of Appeal was to allow Simon's appeal.)
In Court of Appeal cases, it is the ratio of the decision which will have the binding effect of precedent both on lesser courts (such as the High Court) and indeed (in most circumstances) on the Court of Appeal itself.
It is thereby important to work out exactly the ratio of any Court of Appeal case.
The second term is obiter dicta. What is said obiter by a court is not essential to the order made by the court.
A court may set the background to the case, or make observations on the conduct of the parties, or remark on the state of the law generally; but unless the order made by the court can only be explained by reference to these statements, they can be said to have been obiter.
Insofar as obiter statements are about law, they do not bind other courts, though they can be of “persuasive” effect: that means a court can adopt such a statement as having effect should that court be persuaded that the statement be relevant in case before it.
But with the ratio, a court may have no choice: it is a binding precedent.
The task for those analysing an appellate case is to try and sort the ratio from the obiter dicta, though such analysis is provisionally academic until its soundness is tested in actual future cases.
For me, the ratio of BCA v Dr Singh consists of the Court of Appeal’s reasoning on jurisdiction and on meaning.
Ratio – jurisdiction
The first hurdle for the Court of Appeal was the extent they could actually hear the appeal. This is a dry-ish point about jurisdiction, and so feel free to now scroll down to the really interesting part of the ratio on meaning.
The BCA contended that the Court of Appeal should only disturb the ruling of Mr Justice Eady if, in effect, it was outside the range of rulings available to him; that the ruling may perhaps be wrong, but not so wrong that the Court of Appeal should intervene and overturn it.
Here it is significant that Mr Justice Eady was, with the agreement of the parties, determining the question of meaning which is usually left to juries in defamation cases. Normally the judge would rule on whether the words were capable of carrying a certain meaning.
The Court of Appeal’s reasoning on this point is in paragraphs 13 to 15, which I now set out:
13. What the words in issue in a libel action mean is subject to two controls: a decision, reserved to the judge, as to whether the defamatory meaning alleged by the claimant falls with the range of possible meanings conveyed by the words in their context; and a decision, traditionally reserved to the jury, as to what they actually mean. The former is regarded as a question of law, the latter as one of fact, with the result that the meaning eventually decided upon by the jury is shielded from attack on appeal save where it has crossed the boundary of reasonableness.
14. Heather Rogers QC for the BCA accordingly submits that we cannot interfere with Eady J's decision on meaning simply because we may disagree with it: we can only do so if we are quite sure that he was wrong. Adrienne Page QC for Dr Singh submits, first, that we are free to retake that decision if, as she submits is the case, it is vitiated by an error of law; but she submits in any event that the deference accorded on appeal to what is ordinarily a jury's verdict has no equivalent where the finding in question is the speaking decision of a judge.
15. Ms Page draws our attention in this connection to Slim v Daily Telegraph [1968] 2 QB 157, an appeal from a decision of Paull J who, as is to happen in the present case, had tried a libel action without a jury. Diplock LJ (at 174) explained the two functions in this way:
"The decision as to defamatory meanings which words are capable of bearing is reserved to the judge, and for this reason, and no other, is called a question of law. The decision as to the particular defamatory meaning within that category which the words do bear is reserved to the jury, and for this reason, and no other, is called a question of fact."
The purpose of this careful explanation becomes apparent when, having held that the trial judge had failed to direct himself adequately as to the true meaning of the words complained of, Diplock LJ (at 177) asks "What then is this court to do?" and answers:
"I do not think we need send it back for a retrial …. This court is in as good a position as the judge to determine what is the natural and ordinary meaning of the words…."
In other words, the BCA’s case on the jurisdiction point was rejected.
The Court of Appeal could decide meaning for itself.
This means it should be easier for losing parties to appeal adverse rulings of the High Court on meaning in defamation cases when the parties elect not to have a jury trial, as – because of significant additional cost of jury trials – parties may increasingly do.
(In view of what the Court of Appeal then say about meaning, it is arguable that this point on jurisdiction is obiter - the Court of Appeal seems to go on to say that the meaning adopted by Mr Justice Eady was outside the meanings available to him – and so the appeal could have been allowed even if the BCA’s submissions on jurisdiction had been correct. However, I regard the jurisdiction point as ratio as it seems to me to go to the jurisdiction the Court of Appeal is exercising in ordering that the appeal be allowed.)
And now the really interesting part of the ratio.
Ratio - meaning
Once that the Court of Appeal had satisfied itself as to its jurisdiction, it could then approach the “words complained of” which (of course) were:
"The British Chiropractic Association claims that their members can help treat children with colic, sleeping and feeding problems, frequent ear infections, asthma and prolonged crying, even though there is not a jot of evidence. This organisation is the respectable face of the chiropractic profession and yet it happily promotes bogus treatments."
The Court of Appeal was careful, as Lord Justice Laws had done in granting permission, to set out the whole paragraph containing the words complained of and the following paragraph where Simon sets out why he describes the treatments as bogus.
The Court of Appeal starts with the word “evidence” and then construes what “not a jot of evidence” would thereby mean:
26. What "evidence" signifies depends heavily on context. To a literalist, any primary fact – for example, that following chiropractic intervention a patient's condition improved – may be evidence of a secondary fact, here that chiropractic works. To anyone (and not only a scientist) concerned with the establishment of dependable generalisations about cause and effect, such primary information is as worthless as evidence of the secondary fact as its converse would be. The same may equally well be true of data considerably more complex than in the facile example we have given: whether it is or not is what scientific opinion is there to debate. If in the course of the debate the view is expressed that there is not a jot of evidence for one deduction or another, the natural meaning is that there is no worthwhile or reliable evidence for it. That is as much a value judgment as a contrary viewpoint would be.
This is an extremely interesting paragraph.
It appears to establish a class of statements (and not just in scientific debates) which are “concerned with the establishment of dependable generalisations about cause and effect” where contentions about evidence are inherently “value judgments” - that is, expressions amenable to the defence of “fair comment” (or "honest opinion" as the courts now prefer to call it).
Accordingly, if a statement is “concerned with the establishment of dependable generalisations about cause and effect” then, following British Chiropractic Association v Dr Singh, there will now be a presumption (which can be rebutted by evidence of malice) that there will be a defence to a defamation suit.
(Unless this case is superseded in some way by a Supreme Court judgment and then the ratio can fall away.)
In my analysis, this reasoning of the Court of Appeal is part of the ratio of the case. And, if I am correct in this, then this will bind the High Court (and effectively the Court of Appeal, but not the Supreme Court) in future cases.
If so, this will have more direct effect than the wonderful Easterbrook quotation, which was clearly obiter.
I have to stress that I may well be incorrect on this; whether I am right or not is subject to the hard reality test of future libel cases.
But it does seem very interesting.
(Here I would like to pay tribute to Professor Stephen Curry who spotted the potential significance of paragraph 26 well before me.)
Having decided this about “evidence” and thereby “not a jot of evidence” - and providing an illustrative example in paragraph 27 - the Court of Appeal goes on to make short work of “bogus”:
28. Ms Rogers has understandably not sought to make a major issue of the word "bogus". In its context the word is more emphatic than assertive. But it is also explicitly supported by the next paragraph of the article, which explains that Dr Singh's co-author Professor Ernst had found in 70 trials no evidence that chiropractic could treat conditions unrelated to the back. It is a paragraph which also underlines the evaluative character of the assertion that there was not a jot of evidence for such claims.
And “happily”:
29. The other assertion to which the BCA takes objection is that it "happily" promotes treatments which, if Dr Singh is right, are bogus. Eady J accepted the BCA's case that this meant, in its context, that the BCA was well aware that there was in reality no evidence to support its claims – "the plainest allegation of dishonesty", as the judge put it.
And the Court of Appeal then construe the words complained of as a whole and provide the Court of Appeal’s own ruling on “meaning”:
30. Once the allegation that there is "not a jot of evidence" to support the claims is properly characterised as a value judgment, the word "happily", even if synonymous with "knowingly", loses its sting. But we respectfully doubt whether the judge was justified in any event in attributing to the word any significance beyond, say, "blithely". The natural meaning of the passage, in other words, was not that the BCA was promoting what it knew to be bogus treatments but that it was promoting what Dr Singh contended were bogus treatments without regard to the want of reliable evidence of their efficacy – a meaning which takes one back to the assertion that there was not a jot of evidence for the BCA's claims.
In short, the meaning of the words complained of is that the BCA was promoting what Simon contended were bogus treatments without regard to the want of reliable evidence of their efficacy.
And unless the Supreme Court overturns this, all Simon has to show to defeat this is that he was not acting maliciously.
Conclusions
What the Court of Appeal required to determine the appeal is set out in paragraphs 13, 14, and 15 on jurisdiction and in paragraphs 26, 28, 29, and 30 on meaning.
The judgment could – with some slight modifications - have consisted just of the reasoning in those paragraphs combined with the introductory paragraphs 1 to 9 and paragraph 37 describing the order made.
The remaining literary fireworks of the judgment – the mention of an Orwellian Ministry of Truth, the quoting of Milton on Galileo, the Easterbrook passage, and so on – all fall to be regarded as obiter.
These obiter statements are vivid, exhilarating, heady stuff. In particular, it would be delightful if the Easterbrook passage was seen as an expression of the English legal position.
But these statements will only ever have persuasive effect, if any effect at all, on future English libel litigation.
The eminent blogger The Heresiarch has examined these statements and finds many of them intellectually unsatisfying.
He complains that the Court of Appeal was “engaged in piece of casuistical manipulation to reach its preferred result”: it was the right decision, but for the wrong reasons.
I am afraid I have to differ. The Court of Appeal did not actually need any of these colourful passages for the appeal to be allowed, for none of these statements were part of the ratio.
The Court of Appeal simply did not need them to reach its "preferred result".
So why were these obiter statements made?
In my view, the Court of Appeal is consciously giving a steer to potential claimants and their lawyers, and perhaps even the High Court itself, about the general approach which should be adopted in defamation cases.
In particular, I believe the Court of Appeal is signalling the values which courts should have regard to in dealing with such defamation cases in future.
And a Court of Appeal consisting of the Lord Chief Justice, the Master of the Rolls, and Lord Justice Sedley is in an extremely powerful position to make these signals.
Insofar as these obiter statements do not hang together then this is more because of it being a jointly-written judgment.
In my view, the judgment is tightly reasoned where it matters, that is the ratio on meaning.
Overall, I think the judgment is important and welcome, as well as inspiring and emphatic.
That Simon won this appeal is delightful; to do so in a judgment in such striking and – one hopes – influential obiter terms is uplifting; but to have prompted the Court of Appeal to determine that “fair comment” (or “honest opinion”) can cover all statements “concerned with the establishment of dependable generalisations about cause and effect” may be the most enduring result of this case.
But in no way does this judgment correct the wider manifest faults of English libel law and the campaign for libel reform must press on.

Why can't the judges be explicit about what is ratio and what is obiter dicta?
Thank you! I read the judges' ruling, and although I grasped the overall meaning of it, you have clarified and simplified its meaning for us lay people. We are, once again, in your debt.
sg.
I have struggled to understand the legal distinction between fact and opinion, because in medical science facts have (for practical purposes) been regarded as opinions for decades now.
In 1935 Ludwik Fleck explained how medical "facts" can change over time, and are therefore no more than more or less well established opinions. Fleck's book was translated and published in 1979 as "The Genesis and Development of a Scientific Fact"; Fleck's ideas were a key source of inspiration for Thomas Kuhn and his revolutionary book "The Structure of Scientific Revolutions" (1962).
Today most medical scientists, even if they have never heard of Fleck or Kuhn, take it for granted that evidence is a set of facts that can change with further research. In fact, critical appraisal of research ranks evidence by the likelihood that it will change with future research.

SomeBeans has already asked my main question: why doesn't a judgement make it explicit which parts are binding as precedent and which are passing comments? It seems to me this only makes more work for future courts, and more uncertainty for future litigants.
PS. I see the Wikipedia link for "ratio" has been fixed, but the link for "obiter" is missing an "en" at the start.
Good question re ratios and obiter dicta - a question every law student asks too, and many of us in practice.
The answer (I think) is that it is up to courts in subsequent cases to work out the binding ratio of an earlier case, with the benefit of argument from the parties.
It is not for a court to "declare" how future courts will be bound - this would be, in effect, legislation by another name, but for the later court to decide, after argument from both sides in a case, the extent to which it is bound.
I know this is open to fairly obvious questioning, but in practice it works better than the original court asserting how it thinks following courts should be bound.
This approach is common to all common law jurisdictions; and it helps prevent judicial legislation.
The downside is that it can be an expensive work-creation scheme for subsequent lawyers as they argue over the possible ratios of an earlier leading case.
In the olden days, before separate numbered paragraphs, the situation was a lot worse. The introduction of numbered paragraphs about ten years ago greatly improved the job for those analysing cases.
twaza,
You need to distinguish data, which can *never* change, from the ideas you might draw from them, which might change as other data arises.
"Facts", i.e. raw data, can never change.
Things that change could never have been facts, i.e. they could not have been directly derived from raw data. They must have contained some kind of interpretative element that would allow them to change. The presence of that interpretative element would render them not a fact, but a hypothesis, theory, whatever.
For example, in Bonfort's recent paper examining the evidence for chiropractic practices, the raw data, the counts in the individual studies Bonfort et al survey, will never change, for all time and cannot. "The data are the data."
I wrote about this recently, see the link on my name.
(Links to article: "You can change the ideas, but not the data.")
A couple of queries:
You say that the juristiction point in 13-15 seems to you to be ratio. But does not the judgement itself, in 31, explicitely state that the point is obiter? The case referred to in the words: "Nor is it necessary to decide whether, following the reasoning in Slim v Daily Telegraph, we should substitute our preferred meaning for that found by the judge" (from 31) is clearly the same case referred to in 15. What does that mean?
Also, for the sake of completeness I hope you'll shed more light later about 35-36.
This judgement really is very interesting for defamation law, not just in the UK but down here in Oz where I am too. After all, we do still happily look to UK decisions from direction, we haven't shut that avenue off just cos we don't appeal to the privy Council any more.
It seems to me that this is likely to be very influential in the thinking about defamation actions in the commentary and opinion publishing space i.e blogs (whether of media organisations or individuals), tweets and formal opinion and feature writing pieces. And it is not such a departure from existing defamation law - fair comment is a defence to a defamation claim but it's important, if you want to preserve that avenue for yourself against a claim, that you actually publish it as comment. Not some 'gotcha' of fact. you need to indicate it's an opinion/comment and you need to include in your publication some of the evidence on which you rely to form the opinion.
That's existing defam law about fair comment and it's terrif that Singh's legal team was able to focus thorugh all the minutiae of elements to convice the appeal court to agree. Seems to me Justice Eady preferred to read Singh's piece as a statement of fact instead of comment, and that's where he went wrong.
Jack, great blog - any idea if Singh's legal team changed between the start of the action and the appeal? Did he have his QC in place before Eady? I am just curious - seems to me defam is as much about the lawyers as it is about the actual claims.
Thanks for your time, effort and insight. lt's very much appreciated
"The downside is that it can be an expensive work-creation scheme for subsequent lawyers as they argue over the possible ratios of an earlier leading case."
Heh. To use a legal phrase in its more colloquial sense, res ipsa loquitur.
Grant Jacobs, at the pragmatic level I think every reasonable person would agree that the data are the data, and therefore "You can change the ideas, but not the data."
This sort of discussion very quickly leads to one into deep philosophical waters where I feel rather insecure, but let me try to explain what I was getting at.
It is often a problem to establish just what the data are, as your blog makes clear. Are the data what you think you heard? Or, what I think I heard. Or what the speaker says they said?
It is also a problem to decide what the primary data are. For some people they are published research results. For the researchers the primary data might be the numbers in their computer files. Or, they might be the numbers in patients' files. Or, the numbers printed out in a lab report. For a philosopher, the primary data might be the sense impressions made on your brain by a dial on a machine.
Consider "there is not a jot of evidence to support the use of chiropractic for infantile colic".
For Simon Singh, Edzard Ernst, and any rational clinical scientist, the body of evidence is so unreliable that the opinion is treated as a fact. However, some chiropracters might contend that Simon and Edzard did not include some relevant studies, and unfairly dismissed those that they did.
This is the problem that alarmed the judges in Simon's appeal. To establish in a court of law what the facts are entails calling expert witnesses, and cross examining them. Unfortunately the judges chose a misleading example: chiropractic to treat infantile colic. This is misleading, because it is easy to show that there is no good supporting evidence. But consider chiropractic for persistent non-specific low back pain. Chiropractors would say that there is good evidence. Simon hedged and said that there might be evidence. I would say that the evidence is very unreliable, because the best trials are not blinded, and the results are at therefore at high risk of bias. (By the way, one research group reanalyzed their data, and wrote a paper saying that the evidence is better than they first thought --- and thus providing an example of how the relevant data can change.) These differences of opinion should be settled by scientific debate outside the courtroom.
Evidence is not just a fact, or a collection of independent facts. It is more like a web, part of a very large crossword puzzle, where what goes into one square either corroborates or disconfirms the guesses that go into distant squares --- and vice versa. Even when everything fits locally, some distant answer can have knock on effects that change everything.
Scientific revolutions, where some discovery changes everything, seldom happen. So, in practice much of the time we can talk about facts as being uncertain and unchanging, and the data as being the data.
Thanks for the lucid explanation of ratio and obiter. Could you comment on para 11? Do I correctly parse the passage beginning If so as: "If it has had such a chilling effect, then (apart from raising interesting legal questions) the main effect of this litigation has been to leave unresolved the validity of Dr Singh's criticisms. This stifling of important debate is an undesirable consequence of current law and practice."
And, how do you read the last sentence of para 12? Maybe: "Current law and practice can allow dodgy organisations to silence critics, but, alas, we have to follow the law."?
WB: It seemed to be the same team for both hearings. Ms. Page QC is mentioned by name in Eady's judgment.
Cut to the chase through this nonsense....what these judges did was outright gerrymandering.They have in essence altered reality and weighted this case irrationally in favour of the writer.
This now must go to trial.
Dr Mike
It's possible you slightly mistook my point about "preferred result". I didn't say that the judges needed the extraneous passages (which were clearly signposted as obiter) to reach their preferred result. Rather, I regard them as evidence as to what the preferred result was. My problem is really that there's an intellectual sleight of hand going on: the narrow points of reasoning are really a mechanism for reaching the preferred result, but the reasons for preferring it are set out in those obiter passages which are not, and could not be, directly decisive.
In other words, the Court thinks it has found a subtle way - a particular definition of evidence - which sidesteps the true issue, which is whether matters of scientific debate should ever be subject to libel suits. The implication (as you set out so clearly) is that the answer is No, but because they have chosen to manipulate Simon's words they've avoided saying so. This leaves the law rather confused. It also fails to address the main points of the BCA's case, as set out in their QC's submission. This, I think, may give grounds for appeal.
I'm torn about this prospect. On the one hand, obviously the best result would be for the BCA to throw in the towel and Simon can get on with his next book. On the other, part of me hopes the case does go on to the Supreme Court, which might produce a more coherent statement of the law. Because whatever you say about it this judgement is a dog's breakfast.
To return to what I see as the central artificiality of the CA judgement, it does violence to the plain meaning of Simon's article, which is that the BCA were behaving improperly - not dishonestly, but improperly - in not ascertaining the true state of the evidence before making the now notorious claims. That's what the BCA objected to, not whether their evidence was as valid as Ernst's evidence, but that their thinking so made them a public menace.
Eady interpreted Simon as saying more than he actually said. The CA interpreted him as saying less than he actually did. Neither is a good outcome.
If the CA had made more use of the Strasbourg jurisprudence and the HRA they could have used the case to create a proper public interest defence which would have dealt with not just Simon's case but other subsequent ones too, and done so plainly. So this is really a missed opportunity.
"They [the justices] have in essence altered reality and weighted this case irrationally in favour of the writer."
No, they have parsed the meaning from the whole article, labelled opinion as opinion, and redressed Eady's bizarre ruling which had irrationally weighted the case in favour of the BCA.
As many here and on numerous other sites have commented, in no other country in the Western world would this libel case have made it past the initial hurdles, given the safeguards most legal systems have for "robust expression of opinion" and "free comment on matters of public interest and debate".
If the legal system and the politicians are now moving to bring the UK in line with everywhere else, then it is very welcome, though long overdue.
@JackOfKent
"The answer (I think) is that it is up to courts in subsequent cases to work out the binding ratio of an earlier case, with the benefit of argument from the parties.
It is not for a court to "declare" how future courts will be bound - this would be, in effect, legislation by another name, but for the later court to decide, after argument from both sides in a case, the extent to which it is bound."
Does this mean that the judge in one subsequent trial could interpret "ratio" broadly and include a large part of the current judgement therein, then the judge in a further trial interpret it more narrowly.
In other words, could the second subsequent trial judge choose to regard something as not being a binding precedent which was regarded as binding precedent by the judge in the first trial? Or does the use of precedent in one trial have the effect of setting it in stone for later trials?
Let me get a few things I didn't write out of the way first. Excuse me if I'm spelling this out too firmly.
Regards:
It is often a problem to establish just what the data are, as your blog makes clear.
I wrote nothing about there being "a problem to establish just what the data are", nor does my article "make that clear".
I'm not interested in philosophy. I only wrote about science; the non-science examples are not relevant to what I was writing about.
Pragmatically it's usually fairly simple to know what's data and what's not. At the lowest level data is just what you measure directly. (Things that can be directly taken from that can be consider data too, but let's leave that aside.)
I didn't say anything about Simon's case; my comment was not about his case. I was just pointing to your use of 'fact' and saying it can change.
Moving on, I sense you mean well, but I don't think you understand as you refer to different things as if they were the same. For example you write:
By the way, one research group reanalyzed their data, and wrote a paper saying that the evidence is better than they first thought --- and thus providing an example of how the relevant data can change.
This is not an example of data changing. The word 'data' should not appear in the last phrase. The interpretation changed, perhaps from the addition of further data, perhaps from different methodology used in drawing the interpretation.
Ironically, cautioning of people against making this particular class of error—confusing data and interpretation—is the main point of my article. (It's frustrating watching you make this error.)
I'm aware of what evidence is btw; you seem to be confusing me with a non-scientist.
Also, you write:
In fact, critical appraisal of research ranks evidence by the likelihood that it will change with future research.
I'm going to use data and inference for clarity. As you don't make explicit what is being ranked, I will presume you are referring to collections of statistical studies.
What is ranked is the likelihood that the statistical inference drawn from the data will remain the same on further data being obtained.
The existing data doesn't change (more data can be added to make a new dataset, but the existing data is what it is).
The inference may possibly change, if future data alters the conclusions drawn. Inferences are not data, they are conclusions drawn from data.
I don't think the use of the 'evidence' is helpful in a discussion where inference and data need to be kept distinct. Bear in mind I am writing in a science context.
I agree that court rooms are lousy place for science; I've written as much on my own blog.
Small nitpick: blog means the whole blog; you mean post or article. (Sorry about that, but a number of science communicators are getting a bit frustrated at people using this ambiguity meaning.)
I'm going to leave it at this, as this is a side-line away from the conversation and I don't wish to disrupt this thread.
As I read the case, the newspaper reports and the blogs; the thought that comes to mind is that the name of the dog that doesn't bark is Daubert.
Daubert's absence in this case is needlessly expensive; whilst in other cases (eg R v Hoey), it is tragic.
(And all because of the effect it would have on the admissibility of fingerprint evidence).
Grant Jacobs
I must beg to differ with you on a number of issues.
If evidence and data were straightforward to interpret, many philosophers, lawyers, and scientists would be unemployed. To quote Ben Goldacre: "Its a bit more complicated than that."
When I mentioned data and evidence I had in mind the kind of data and evidence that would be needed to assess the statement that there is not a jot of evidence that chiropractic treatments are effective for childhood ailments such as infantile colic.
This data and evidence would be provided by a systematic review of the relevant studies of chiropractic for infantile colic. For the systematic reviewer, the data are the results of the included trials. For the authors of the individual trials, the data are what they analysed to produce their results.
Whether the systematic review provides a quantitative or qualitative summary of the evidence, one still should rank the results according to a qualitative assessment of the risk of bias and error. This risk assessment can be articulated as the chance that future research will change the present assessment.
Finally, as far as language goes, you seem to be a precriptivist, while I am a descriptivist who is quite comfortable with polysemy.
"The downside is that it can be an expensive work-creation scheme for subsequent lawyers ..."
You say that like it's a bad thing. :-)
I noticed Dr Aust, I believe, referring to Eady's decision as bizarre and he's got a point when you look at Eady's statement that Singh had made "the plainest allegation of dishonesty". I mean, wouldn't the plainest allegation of dishonesty, use, well, the word "dishonesty"? For instance if Simon Singh had instead of "... and yet it happily promotes bogus treatments." written "... and yet it dishonestly promotes bogus treatments". Even just comparing it to "'... and yet it knowingly promotes bogus treatments" you see how far from Eady's meaning Singh was. Eady couldn't have done a better job of making clear the distinction if he'd been trying to get himself overturned. I wonder that after writing that bit of his judgment it didn't give Eady any pause.
