There are two courtrooms in the Court of Final Appeal Building.  Both are on the first floor of the building. 

The main courtroom, known as the Court, is where the Court of Final Appeal sits and hears full appeals and most applications for leave to appeal.

The second, smaller, courtroom, known as Courtroom 2, is used for interlocutory and taxation hearings.  It is sometimes used for applications for leave to appeal.
