The Star Chamber (Latin Camera stellata) was an English court of law that sat at the royal Palace of Westminster until 1641. It was mistakenly thought that in 1487 an act was passe which established a special "Court of Star Chamber" to deal with the nobles; however; the only legislation passed in that year in this context was to set up a tribunal to prevent the intimidation of juries and to stop retaining. It seems to have gone out of use by 1509 and it had no connection with the later Court of Star Chamber whose primary purpose was to hear political libel and treason cases.
