ROBERTO MENA, COBERTON MENA vs. PRIORITY BUILDING SERVICES; LUMBERMAN'S UNDERWRITING, PRIORITY BUILDING SERVICES, LLC; LUMBERMAN'S UNDERWRITING
This case involves a lien claimant, Max MRI Imaging, whose lien was dismissed due to failure to pay the mandatory lien activation fee required by Labor Code section 4903.06(a)(4). The Workers' Compensation Appeals Board denied reconsideration, upholding the dismissal despite the claimant's argument of an oversight. The Board emphasized that the statute's language is mandatory and provides no exceptions for inadvertent non-payment. The ruling also clarified procedural arguments regarding notice, appearances, and the inapplicability of the *Hamilton v. Lockheed Corp.* case.
