Experts Condemn Partisan Attack on Scientific Reference Manual for Judges

"Last month, a government agency erased climate change from a manual that helps federal and state judges understand complex science in court. The political attack on the nonpartisan publication “should concern us all,” its co-authors warn."

"Scientists, engineers, lawyers, statisticians and other experts sounded the alarm Monday about the recent decision to remove a chapter on climate science from an influential reference manual designed to help judges understand complex scientific evidence.

For more than 30 years, federal judges have turned to the Reference Manual on Scientific Evidence for guidance on interpreting complex scientific issues in their courtrooms. The reference, originally published by the Federal Judicial Center, which was established by Congress in 1994 as a research and education agency for the judicial branch, is now co-published with the National Academies of Sciences, Engineering, and Medicine. 

On Jan. 29, a coalition of 27 Republican attorneys general wrote to the Federal Judicial Center, urging the center to “immediately withdraw” the chapter on climate science from the manual’s fourth edition, claiming it was biased and “rife with methodology issues.” 

Accuracy and impartiality of the manual is vital, West Virginia Attorney General John B. McCuskey, who led the effort, posted that same day. “However, the newly added ‘Reference Manual on Climate Science’ chapter was written by authors who are connected to university climate studies programs that promote legal warfare against States and energy producers to push their left leaning political agendas.”"
