Chris Portier RF Evaluation
Chris Portier: RF “Probably” Causes Cancer
March 12, 2021
Expert Report by Christopher J. Portier, March 1, 2021, filed with the Superior Court for the District of Columbia (Civil Division) on March 3, 2021 in the case of Murray (et al.) v. Motorola (et al.) (2001 CA 008479 B).
“In my opinion, RF exposure probably causes gliomas and neuromas and, given the human and experimental evidence, I assert that, to a reasonable degree of scientific certainty, the probability that RF exposure causes gliomas and neuromas is high.”
The detailed report runs 176 pages and includes 444 references and Portier’s CV.
Portier was a long-time member of the staff of the NIEHS and the NTP. He was the Associate Director of the NTP, 2000-2006, and Associate Director of the NIEHS, 2006-2009. From 2010 to 2013, he was the director of the National Center for Environment Health (NCEH) at the CDC in Atlanta, GA. He has been a member of a number of IARC Monograph Working Groups, including the one on ELF EMF (2001) and on RF EMFs (2011).
It is not yet known whether Portier’s report will be allowed to be entered into evidence in the Murray case.
A Daubert hearing —which would determine whether the plaintiff’s case is sufficiently based on mainstream science to be allowed to proceed to trial— is scheduled to begin on July 12 in Washington. (It was supposed to be held last fall, but was delayed.)
The first and only previous Daubert hearing on cell phones and brain cancer was held close to 20 years ago (see MWN, M/A02). On September 30, Judge Catherine Blake of the U.S. District Court in Baltimore ruled that the evidence for such a link had not “gained acceptance the scientific community” (see MWN, S/O02).

Defense Seeks To Bar Portier Testimony
April 1, 2021
As expected, defense lawyers have asked the DC court to not allow Christopher Portier to be an expert witness in this case.
In a filing yesterday, the team representing the cell phone industry, argued that, “[A]llowing a new expert four months before the long-planned Daubert hearing would disrupt the existing schedule and unfairly prejudice Defendants.”
The filing was signed by Terry Dee of McDermott Will & Emery in Chicago on behalf of himself and 37 other lawyers at 23 law firms.
Portier was retained by the plaintiff attorneys in March 15, 2015 with the payment of a $5,000 retainer. It is not clear why his report was filed last month, close to six years later.
No word on when the judge may rule on Portier’s participation.
Judge Bars Portier from Serving as Expert Witness
April 21, 2021
Today, Judge Alfred S. Irving, Jr., denied the plaintiff’s motion to allow Christopher Portier to serve as an expert witness.
“[A]llowing Dr. Portier’s testimony four months before the Daubert hearing is scheduled to begin would disrupt the existing schedule and detrimentally affect the orderliness and efficiency of any trial,” he wrote in his decision.
