Key legal question
Whether the appellant was validly summoned to the first-instance hearing by warrant instead of written citation under cantonal procedure.
Extracted holding
No. The warrant-based summons was not justified; a written citation should have been used.
Extracted reasoning
The authorities knew her address and she was already aware of pending proceedings. Her conduct made the procedure difficult but did not justify assuming she would not appear. Relying on a warrant made attendance dependent on chance and was arbitrary under cantonal procedure.
