Following an assessment of a case of the toxic exposure of veterans that occurred during active military, naval, air, or space service under subsection (c), or their dependents, the Working Group may develop a recommendation for formal evaluation under
section 1173 of this title to conduct a review of the health effects related to the case of exposure if the Working Group determines that the research may change the current understanding of the relationship between an exposure to an environmental hazard and adverse health outcomes in humans.
