Star Chamber from WikiPedia:

The Star Chamber (Latin Camera stellata) was an English court of law that sat at the royal Palace of Westminster until 1641. It was made up of Privy Counsellors, as well as common-law judges, and supplemented the activities of the common-law and equity courts in both civil and criminal matters. The court was set up to ensure the fair enforcement of laws against prominent people, those so powerful that ordinary courts could never convict them of their crimes. Court sessions were held in secret, with no indictments, no right of appeal, no juries, and no witnesses. Evidence was presented in writing. Over time it evolved into a political weapon and has become a symbol of the misuse and abuse of power by the English monarchy and courts.

It was mistakenly thought that in 1487 an act was passed 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, the keeping of private armies by persons of rank.
