Key legal question
Whether the appellants were denied the right to be heard because they were not granted an oral hearing before two cantonal instances and because evidence was allegedly ignored.
Extracted holding
No denial of the right to be heard was shown; the cantonal court sufficiently dealt with the relevant evidence and no entitlement to two oral cantonal hearings existed.
Extracted reasoning
The appellants were heard before the cantonal court, and they identified no cantonally guaranteed right to a hearing before two instances. The disputed letter was in the file, and the cantonal court at least implicitly deemed it irrelevant.
