Mr. Moxley was appointed in 1982 by Wyoming Governor Ed Herschler and served for several years as an Assistant Public Defender for Platte and Goshen Counties; during his tenure, he represented an innocent man charged with murder, in the matter of State of Wyoming v. Martin Frias. Initially convicted, Mr. Frias was acquitted on re-trial in 1986, after Mr. Moxley developed forensic evidence to prove that the alleged victim committed suicide. The Frias case was featured on The West, a syndicated television magazine with John Gibson on KCRA, Channel 3 in Sacramento, California and Mr. Moxley also appeared with Mike Wallace on 60 minutes in a lead segment featuring the case.

Mr. Moxley obtained reversal in the Federal Circuit of the denial of compensation to a vaccine-injured child in the case that went to the United States Supreme Court as Shalala v. Whitecotton.
