- In medieval castles, a chamber was a private bedroom or sitting room.
- Later, a chamber came to mean a hall used by lawmakers.
- Still later, the term for the room came to be applied to those who used it: a body of lawmakers and judges was considered a chamber.
The judges met in the chamber to determine the outcome of Sir Knobbly's sad case.
The Star Chamber, established in the reign of Henry VII, was a body of judges accountable to no one but the king.
