Membership nonprofit organization - the board wants to cancel membership to avoid future elections.

We have a public nonprofit organization which was originally formed by three directors. The foundation was formed to be a legal face of a Bulgarian school. We adopted bylaws that included membership and early elections of the board. When it was time for the first election two of the directors passed an amendment with restrictions for the number of the potential candidates (one every year), so the chance that the board has two or three new members at one election was eliminated. I left the board and a new director was elected. This year thesaurus two directors have passed a new amendment canceling all membership so no elections are required and they can stay as directors indefinitely. Is it legal to cancel membership once it has been passed in bylaws and doesn't that require them to change the status of public to private foundation. They have not yet engaged in any charity activity, and their funds so far has been acquired by two 1-2k donations, a subsidiary from the Bulgarian department of education in the amount of around 3k, membership fees around 1.3k for last year and tuition fees from the parents of the students. I am still a member of the foundation and a parent of two of the students attending the school, but now that they are canceling the membership I would like to know if that leaves me with any options for action to prevent this drastic change of rules or at Least force them to change their status from public to private.
