The computer scientist John Mashey has called once again for the Department of Justice to investigate Edward Wegman on a charge of misleading Congress with his 2006 report on the famous and famously resilient “Mann Hockey Stick.”

In a new report now available on the Deep Climate blog, Mashey doesn’t exactly accuse Wegman and his team of lying, cheating and incompetence. Rather, he offers more than 200 pages of evidence: documented examples of Wegman and leading writer Yasmin Said plagiarizing material, padding their references, “crediting” reviewers who either never saw the report or whose comments were ignored, injecting errors into plagiarized text and failing to perform the actual statistical analsysis that the House Committee on Energy and Commerce had requested.

If Wegman hopes to maintain a shred of academic credibility, he must either sue Mashey for libel (and win) or apologize and admit that the 2006 report was a political put-up job. Given the weight of Mashey’s evidence, a lawsuit seems laughably unlikely. A charge of misleading Congress, on the other hand, awaits only the interest of the DOJ.
