CAMCORP ENVIRONMENTAL, LLC, MISSOURI EMPLOYERS MUTUAL INS. CO. and TREASURER OF THE STATE OF MISSOURI AS CUSTODIAN OF THE SECOND INJURY FUND Missouri Cases

Kevin Parvin appealed the Labor and Industrial Relations Commission's denial of his worker's compensation claim, which had affirmed the Administrative Law Judge's (ALJ) findings that Parvin was not a credible witness and his medical expert was less persuasive than the employer's. Parvin challenged the ALJ's credibility determinations and weighing of evidence. The appellate court affirmed the Commission's award, holding that Parvin failed to follow the mandatory analytical process required to challenge such determinations and that the weighing of conflicting medical testimony is solely within the Commission's discretion.
