Questão jurídica principal
Whether the president of the cantonal tax appeal commission had to recuse herself for prior professional involvement as an attorney against the appellant.
Decisão extraída
The recusal request was unfounded; the prior, long-closed labour dispute did not create an objective appearance of bias in the tax case.
Fundamentação extraída
A past, isolated mandate in an unrelated matter, ended years earlier and involving different parties and legal questions, does not by itself establish an appearance of partiality. The appellant showed no concrete circumstances suggesting influence in the present tax appeal.
