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.
