Questione giuridica chiave
Whether the Zurich authorities arbitrarily denied stepchild status under § 23 Abs. 1 lit. b ESchG
Decisione estratta
The interpretation was not arbitrary; only children of the spouse in a legal child relationship qualify as stepchildren for this tariff provision.
Motivazione estratta
The tariff distinguishes mainly by degree of kinship and uses stepchild/stepfather privilege as a narrow exception based on presumed closeness, not on affinity alone. There was no settled practice requiring a broader reading.
