The Woonsocket Board of Assessment Review ("Board of Review") violated the OMA when it convened into executive session. The evidence was completely devoid of any open call as is required pursuant to R.I. Gen. Laws § 42-46-4(a). See R.I. Gen. Laws § 42-46-5(a). Because we conclude that the Board of Review violated the OMA when it did not comply with the requirement of an "open call" and provided no evidence or argument that it convened into executive session for an appropriate purpose, we required that the Board of Review release the December 19, 2017 executive session meeting minutes.
