Most criminal cases are heard by a single professional judge in a district court. Serious cases can be heard by a panel of three judges, and a narrow category of the gravest offences may be heard by a jury if the defendant asks for it. There is no plea bargaining in the American sense, but there is a "special procedure" — a shortened hearing where the defendant agrees with the charge in exchange for a sentence capped below the statutory maximum. It looks attractive and it is frequently the wrong choice, because it forfeits the right to challenge the facts on appeal.
The prosecution presents its evidence first, then the defence. The judge is active: they question witnesses directly and control the pace. Hearings are often spread over weeks with gaps between sessions, which means a trial can run for months without anything visible happening.
