You need to read thru your prospectus/house rules/bylaws/proprietary lease/governing documents. Those documents determine what can be changed by the board or voted on by the members of the corporation, and how the board gets elected/selected/appointed. In general, you should be able to read the board meeting minutes, probably at the management company's office, and you should receive an annual audited financial statement. You can make a complaint to whatever state authority governs your property, often the State Attorney General, if they don't permit review of the minutes or fail to provide financials, etc. The board has a fiduciary duty to follow the governing documents. Run for the board.
