Key legal question
Whether the appeal could challenge the four-month driver's license withdrawal on the ground of excessive delay.
Extracted holding
The complaint was admissible only within the limits of proper substantiation; the unsubstantiated attack on the assessment of the withdrawal duration was not considered.
Extracted reasoning
The court held that the appellant did not specifically and sufficiently challenge the cantonal court's reasoning on the proportionality of the four-month withdrawal, so that part of the complaint failed the federal pleading requirements.
