The governor is hereby authorized and empowered, at such times and for such purposes as he may deem necessary or advisable, to create special commissions consisting of as many members as he may deem appropriate, with the powers and duties as hereinafter prescribed. Each of such commissions shall be designated and known by some suitable name. Whenever in the judgment of the governor, any special commission created under this act has fully completed the work assigned to it or fulfilled the purposes for which it was created, or the need for such a commission for any reason no longer exists, the governor may, by executive order declare such commission dissolved and the members thereof shall thenceforth be relieved of all official duties as such.
