Questione giuridica chiave
Whether the federal complaint could challenge the conviction for driving despite licence withdrawal on the basis of a newly raised constitutional right-to-silence claim.
Decisione estratta
The complaint could not be entered into because the constitutional objection was raised for the first time before the Federal Supreme Court.
Motivazione estratta
New legal arguments are in principle admissible, but constitutional complaints must have been raised before the last cantonal instance; the exhaustion and pleading rules were not met here.
