Amending Bylaws

I sit on the BOD for a relatively small, yet growing HOA (non-profit corp.) in Maine. Prior to my moving here, the Board had proposed changes to the bylaws that were approved at the annual meeting in 2001. However, I am challenging one of the supposed revisions that has become a point of controversy within the community. A major change was made to the "PURPOSE" statement in the bylaws, that is now inconsistent with the "PURPOSE" statement filed with the Secretary of State. Aside from some scribblings on rough drafts, there is no record in the minutes to that annual meeting what the proposed revisions were. Also, no version of the original bylaws nor the revision was ever filed in the registry of deeds. Am I wrong to assume that a judge, if that is the path taken, would find the original version valid, as it is the one that is consistent with the Articles of Incorporation currently on file?

Thanks - Lori
