At one meet­ing at least every six (6) months, the agen­da shall include the item: “Review of the min­utes and record­ings of all closed ses­sions that have not yet been released for pub­lic review, and deter­mi­na­tion of which min­utes, if any, may be released.”  Min­utes shall be reviewed in closed ses­sion and shall not be released unless the cor­po­rate author­i­ties of the Coun­ty find that it is no longer nec­es­sary to pro­tect the pub­lic inter­est or the pri­va­cy of an indi­vid­ual by keep­ing them con­fi­den­tial.  As to any min­utes not released, the cor­po­rate author­i­ties shall find that the “need for con­fi­den­tial­i­ty still exists” as to those min­utes.  Min­utes of closed ses­sions shall be kept indef­i­nite­ly.
