Continuity mistake: While in the courtroom Bull walks up to Christine, Dan, and Harry. The shot changes and he walks up to them again.

Answer: The jails are overcrowded, so any petty offenders whose case isn't heard by midnight will be let go. The defendant wants the details of his case read (Instead of just the typical summary of the case that Mack gives Harry) because he knows it'll take a while and run out the clock on the midnight deadline, also sparing him the grand jury trial. Dan speed-recites the document quickly enough for Harry to rule on the case and bang his gavel just at the stroke of midnight.
