Can our HOA Board of Directors for a 136 condominium units, meet in Executive Sessions to make financial /legal decisions without an Open Meeting 1st?

The legal decisions involved settling lawsuit of a new Board member vs. the HOA (owners have not been involved of agreement); hiring of a Property Manager (owners not giving details of agreement nor duties of this person); giving legal representation to the President of the Board for a personal civil suit involving himself and a renter/resident. Using funds without informing the owners about the financial situation for the HOA. Holding only Executive Sessions; posting no agenda; having no Opoen Meeting prior. I have contacted our Attorney General''s Office; our Board is in violation of our Open Meeting laws...do you agree?
