In Norway, at the lower court instance, cases are judged by a panel of three judges, of which two are lay-judges selected from the jury pool. The professional judge can thus be out-voted, but has the ability to correct blatant errors during deliberations. For certain more serious cases, the panel can consist of five judges, of which three are lay-judges.
For the second court instances, which handles appeals from the lower court or serious cases (potentially leading to 6 years or more imprisonment, which in Norway pretty much limits it to murder, serious drug related offences, rape or other serious sexual offences or particularly serious robbery cases), there is a jury and a panel of three professional judges. The jury is selected from the same pool as the lower instance, but generally the selection takes into account experience, so that it generally consists of people with experience as lay judges from the lower court instances.
Which means you'll usually face a jury where the members have previously participated in deliberations with a legally trained professional judge.
If the professional judges do not agree with the finding of the jury, they can set it aside if unanimous (in the case where the jury votes to acquit) or with two votes in the case where the jury votes guilty (and the professional judges wants to set the guilty verdict aside).
If the judgement is set aside, something which is very rare and usually happens only if the jury made obvious substantial errors, the case is retried with three professional judges and four lay judges.
It has warts, but the system with lay judges means that you don't face a group of people who don't understand the system with no corrective input, yet at the same time it still quite frequently happens that the lay judges overrule the professional judges (and the judgement is only rarely overruled), or that the panel is split with a mix of lay judges on professional judges in the majority.
