The District Court in Los Angeles contains at least nine identical courtrooms. These are the main battlegrounds for defense attorneys and prosecutors. During a trial, the defense attorney argues his or her case against the prosecutor by cross-examining the prosecution's witnesses, usually to find information that contradicts the facts (due to perjury or forgetfulness on the witness's part), though other purposes can be fulfilled in this way as well. Trials are conducted as bench trials, which means that the judge who presides over these trials can freely render the verdict. Under the Jurist System in Vera Misham's murder trial, the judge could still hand down guilty verdicts based on accumulated penalties, but otherwise, final judgment was given to a six-member jury to make by consensus.
