Questione giuridica chiave
Whether a revision could be based on the absence of a psychiatric expert report on criminal responsibility under Art. 20 StGB.
Decisione estratta
No. Youth alone does not create a mandatory duty to obtain a psychiatric report; no concrete indications of diminished maturity were shown, so no new fact or evidence existed for revision.
Motivazione estratta
Art. 20 StGB requires expert evidence only when serious doubts about criminal responsibility arise from the circumstances. The appellant did not show any specific retardation of development or other indications that should have triggered such doubts.
