A guest Blogger, PeterP, will explain:
Heckenlively claims to be a lawyer, like most lawyers his skill is therefore to cherry-pick the bits of evidence that suits him rather than looking at it all. This suits an adversarial court system but does not lend itself to finding the truth in science.

Probably because no one has managed to show there is one. The Cedillo case certainly didn't.

Having considered both the general reputation and specific work on measles it concluded :
"However, I conclude that the overall evidence weighs strongly in favor of a conclusion that, whatever the general caliber of the work of the O'Leary laboratory group, the group's measles virus detection work, done largely under the Unigenetics Ltd. name, simply is not reliable. The overall evidence specific to that measles virus detection issue is simply too strong to be outweighed by mere evidence of a good general reputation concerning other work.
In this regard, two further observations are relevant. First, as noted above, the measles virus detection work was done, at least for the most part, under the Unigenetics Ltd. name. Dr. Bustin testified that Unigenetics Ltd. was not accredited, and that Unigenetics Ltd. declined to participate in a quality control program, so that there was never any independent quality assessment made of any of the work that was carried out by Unigenetics. (Tr. 2034, 2057A.)
Significantly, petitioners never attempted to rebut that aspect of Dr. Bustin's testimony.
Second, the record also indicates that Unigenetics Ltd. is no longer in business, and there is no evidence that the O'Leary laboratory has ever published any work defending the reliability of the Uhlmann study, despite the criticism of that study. Thus, it seems that the O'Leary laboratory has not publicly defended the reliability of its efforts at measles virus detection during the early 2000s.
Accordingly, considering all of the evidence of record, I conclude that, regardless of whether the O'Leary laboratory might have a solid reputation with respect to its other work, nevertheless that laboratory's efforts to detect measles virus in the early 2000s were flawed and unreliable."

Using the same Unigenetics Lab as Wakefield. Remember also that Unigenetics was not a university laboratory but a private "for profit" company specifically established to test for an MMR/measles link on behalf of the UK MMR litigants. It was closed in 2005.

The testing was by PCR, I assume Heckenlively knows little about this procedure and how sensitive it is to contamination. To say that "DNA contamination is an issue only if there are relatively low numbers of the virus detected" shows remarkable ignorance.
One of the telling points against Unigenetics was that they produced positive results when it was simply impossible. They omitted the Reverse Transcriptase step in their tests. Measles virus exists as an RNA molecule. The polymerase chain reaction (PCR) assay amplifies DNA. Thus to detect an RNA molecule in a PCR assay, the RNA must first be copied (by the reverse transcriptase enzyme) into DNA, which can then be amplified. Bustin showed that the O'Leary lab reported positive results even when they could not possibly have detected an RNA molecule because they had left out the step to copy that RNA into DNA. Thus the positive results reported for such test were, without any doubt at all, false positives.
>On the issue of reliability, it's curious that while the court admits that the general
>reputation of the lab and Dr. O'Leary are good, they unaccountably failed in
See above. That they failed, and failed abysmally, is beyond question. Why they failed may have something to do with their sole source of funding. They were for example using older instruments, and on some of these faults were discovered by Bustin. For example there was a huge variation in the heating and cooling characteristics across the sample block producing variable results depending on where sample tubes were placed on the instrument.

The US government did not "hire" O'leary, and by the time of Hornig/Lipkin Unigenetics had been closed. Three laboratories were utilised by Hornig/Lipkin, O'Learys Trinity College laboratory at Coombe Women's Hospital,. The Center for Infection and Immunity, New York; and the Measles, Mumps,Rubella, and Herpes virus Laboratory Branch, CDC, Atlanta.

The fact was that no measles virus was detected in the gut. This was the conclusion reached by Chadwick, working with Wakefield, before Unigenetics came into being. As it wasn't the answer which was wanted the work was taken away from a University laboratory and given to a commercial one set up for the purpose.
As a matter of interest the vast majority of samples from autistic tested for MV by O'Leary in the Unigenetics lab in Dublin were from blood, not gut tissue.

There is nothing confusing about there being no credible evidence that measles was in the gut. This is the simple fact that the author seems to ignore.
The Unigenetics findings were false. Unigenetics claimed to have found measles virus in _both_ blood and gut samples. Bustin's lengthy report clearly showed their results were as a result of poor laboratory practice. As Bustin, far more of an expert in PCR than O'Leary ever will be, aid :-
"My clear conclusion then was that O'Leary's results were caused by> The
defective experimental technique and inappropriate interpretation of
results, since he was detecting DNA, and measles virus does not exist
as DNA. "
>Court acted as if these issues weren't even worthy of consideration. And if
>Dr. O'Leary's lab was so incompetent in detecting the measles virus, why did
>our own government later hire him to set up two such labs?
It didn't. He collaborated as a professor at the Department of Histopathology, Trinity College Dublin, Dublin, not as Managing Director of the closed Unigenetics Laboratory Ltd. Unigenetics had some specific problems associated with trying to do things cheaply. Many of the "staff" were undergraduates. Unigenetics was also not an accredited laboratory and Unigenetics had no external quality controls.

Actually, together with recordings of her made beforehand, they were very compelling in showing symptoms of ASD long before she received MMR.

That's correct, it was an opinion of an observer. It could equally well have been made about the temporal association between visiting McDonalds and losing her speaking ability.

However you try to spin it the evidence was overwhelmingly against the claimant. Look at the authors of the Hornig/Lipkin study :- Lack of Association between Measles Virus Vaccine and Autism with Enteropathy: A Case-Control Study Mady Hornig, Thomas Briese, Timothy Buie, MargaretL.Bauman, Gregory Lauwers, Ulrike Siemetzki, Kimberly Hummel, Paul A. Rota, William J. Bellini, ,John J. O'Leary, Orla Sheils, Errol Alden, Larry Pickering, W.Ian Lipkin O'Leary and Sheils are co-authors. If they were that convinced that their Unigenetics work was right why did they support this later studies conclusion which was :-
"This study provides strong evidence against association of autism
with persistent MV RNA in the GI tract or MMR exposure. "
Was it simply because they realised they had been wrong with
Unigenetics and this later, properly conducted, properly documented
and properly supervised work, clearly showed that?
