Key legal question
Whether Y. had standing to file the federal appeal despite not participating below and not being directly affected by the cantonal decision.
Extracted holding

Extracted reasoning
Under Art. 76(1) BGG, only a party affected by the decision and who participated in the previous proceedings may appeal; those requirements were not met for Y.
