The State statute on Open Governmental Proceedings, sometimes called the Open Meetings or “Sunshine” Act, was enacted to ensure that the proceedings of all public agencies are conducted in an open and public manner, so that the people may be informed about the actions of their governments and retain control over them.

Reference Summary West Virginia Code § 6-9A

An HOA is not a public agency.

Member homeowners,  e.g. all unit owners within an HOA retain their attendance rights at board meetings and annual meetings with the exception of executive session.
