This requires a courtroom setup and decoration different from regular courts. They need to schedule breaks for the jury and build a confidential soundproof room for the jury so they can discuss freely without external influence.
However, not all cases require jury involvement.
For example, non-criminal cases, those special cases with major impact, won't introduce a jury, so there are dedicated courts for these cases, and the selection of judges is also different.
Aside from this, there are fast-track courts.
According to Federal Department of Justice regulations, cases with a maximum sentence of less than one year can be processed through fast-track courts.
Of course, fast-track courts can also have defense lawyers, and most cases going through fast-track courts are cases where evidence is conclusive and the defendant has already pleaded guilty, so the trial speed will be fast.
The judge may just glance at the docket and ask a few questions before making a judgment.
