If a mason abuses his power inside the lodge, disrespectful and rude to others, talks behind the worshipful master's back, insults him and other, what can be done to deal with him and what punishments can he face?

Disciplinary action begins with a written charge signed by the accuser and delivered to the Secretary, who reads it at a regular communication 2. Charges may be preferred by Masons or non-Masons if the allegation involves immoral conduct falling under Masonic jurisdiction 2. The trial takes place in a lodge opened in the highest degree attained by the accused, though the final verdict and sentence must be rendered in the Third Degree after both parties and counsel have retired 12. The accused may employ a Master Mason as counsel 1.

A conviction requires a two-thirds vote of the members present, typically decided by ballot 12. If found guilty, the lodge determines the penalty by a show of hands, voting in order on expulsion, indefinite suspension, definite suspension, and reprimand 1. Expulsion and both forms of suspension require a two-thirds majority, whereas a reprimand requires only a simple majority 1.

Masonic penalties carry distinct operational effects:

Expulsion permanently severs membership and Masonic rights 1.

Definite or Indefinite Suspension places all Masonic rights, official functions, and lodge dues in abeyance without destroying Masonic citizenship 1. Definite suspension ends automatically at the term's expiration or by a two-thirds vote, while indefinite suspension requires a two-thirds vote for restoration 1.

Reprimand, delivered publicly by the Worshipful Master or privately, admonishes the offender without altering his Masonic standing 2.

Outside of formal trial procedures, a Worshipful Master holds the prerogative to exclude a disorderly member from a single meeting to maintain peace and harmony, though he remains answerable to the Grand Lodge for his decision 2. Furthermore, acquittals or convictions in civil or military courts do not bar a lodge trial for the same offense, and new trials may be held upon the discovery of fresh evidence to protect the reputation of the Order 1.
