Key legal question
Whether the cantonal court could strike the pending licence-withdrawal appeal as moot after reinstatement of the licence.
Extracted holding
The complaint did not sufficiently show any Federal-law violation in the finding of mootness; review was therefore unavailable on this point.
Extracted reasoning
The appellant relied only on substantive road-traffic law and failed to explain why the procedural conclusion that the appeal had become moot through loss of legal interest would breach federal law or be arbitrary.
