 IV c. 6) was an Act of the Parliament of the United Kingdom of Great Britain and Ireland which made it illegal to hold a meeting of more than 50 people.The provisions of the Act were similar to those of previous Seditious Meetings Acts, such as those of 1795 and 1817, although more severe constraints were added.The law forbade all meetings of more than 50 people called "for the purpose...of deliberating upon any public grievance, or upon any matter or thing relating to any trade, manufacture, business, or profession, or upon any matter in church or state," unless the meeting had been summoned by an authorised official.
