We successfully defended a national home improvement store in the litigation of a claim petition. The petitioner alleged that as a result of his employment at the retailer, he developed back problems and was in need of medical treatment. The defense was able to call into question the petitioner's credibility, as well as that of the petitioner's expert doctor. The judge found that the petitioner did not sustain the burden of proof. Therefore, both the motion for medical and temporary benefits and the claim petition were dismissed, with prejudice.
