What is the queens bench division in the high court of London?

It's part of the High Courts of Justice, usually dealing with "anything else". Business and money cases are dealt with by the Chancery Division, and family and divorce cases are dealt with by the Family Division. The Queen's Bench Division hears cases related to contracts, damages and injuries. It also oversees the lower courts and the government.

The Queen's Bench Division hears appeals from Magistrates and Crown Courts. If the case is a criminal conviction, an appeal goes straight to the Supreme Court. If the case is a lawsuit, the appeal goes to the Civil Division of the Court of Appeal (or occassionally, can be 'leapfrogged' straight to the Supreme Court).
