Yes, a brother can inform the Grand Lodge or Regional Grand Lodge about another brother's misbehavior. According to the Constitution, if any complaint is brought against a brother, the matter should be referred to the Lodge, which is the proper and competent judge for such controversies. If the issue is not resolved at the Lodge level, it can be escalated to the Grand Lodge. Specifically, Rule 155 states that if a brother behaves in a manner that disturbs the harmony of the Lodge, he may be admonished, fined, or excluded from the meeting, and the case may be reported to a higher Masonic authority if necessary.
Furthermore, Rule 156 outlines the process for excluding a member for sufficient cause, which includes serving notice to the brother concerned and allowing him to attend and be heard at the meeting where the complaint is considered.
