Complainant alleged that the MBRTF violated the OMA after its July 19, 2017 meeting when it discussed MBRTF business in the parking lot. Although we were presented with conflicting narratives of what transpired in the parking lot on July 19, 2017, we found credible the five-time corroborated account of MBRTF members. Because the evidence failed to establish that a quorum of MBRTF members ever collectively discussed any matter within their supervision, jurisdiction, control, or advisory power, we found no violation.
