August 2010 – May 2011

Testified for the defense in Ayotte v. State of Montana et al

Testified in deposition a storm that caused critical damage and severe injury was within normal weather expectations concerning and not a unique event outside normal expectations.

Letter of appreciation:

We hired Dr. Berry as an expert witness in a case involving major injuries in which an advertising sign was blown into a highway striking an individual in the face. While the subject sign was rotten and ill-maintained, we faced a particularly strong “act of God” defense, which was supported by an opposing weather expert who claimed the wind was 97 mph. Dr. Berry ably rebutted the defense claims, writing an expert report and performing very well during his deposition. The subject matter was difficult, but thoroughly explained by Dr. Berry. He was obviously very educated in meteorology and atmospheric physics, wrote a great report and handled cross-examination during his deposition well.

Rep Doug Coffin, Professor of Molecular Biology, University of Montana, Missoula, sponsored HJ 10. He and some 16 witnesses from environmental organizations testified that Montana must pass HJ 10.

August – September 2013

Represented plaintiff in Michael H. Peretti v. The Department of Revenue, State of Montana.

Testified in hearing at Montana State Capitol on September 12, 2013, concerning the mathematical and statistical mistakes made by DOR in its valuation of Peretti’s waterfront property on Flathead Lake. This used my mathematical expertise in automated valuation models (AVM) for real-estate valuations. In 1999, I developed complete software for an AVM for a startup company, using artificial intelligence mathematics developed for weather forecasting. In 2000, my AVM scored highest of all models in the Bank of America independent tests. In the Montana case was able to show how the DOR made serious statistical and mathematical mistakes in its valuation of properties for tax purposes.
