The Woonsocket City Council ("City Council") violated the OMA when it amended its agenda at one of its meetings to add an additional item, yet not only discussed this item, but also voted on this additional item. See R.I. Gen. Laws § 42-46-6(b). This Department found no evidence of a willful and knowing violation. We directed the City Council to reconsider and re-vote on the agenda item at a properly posted future meeting.
