Key legal question
Whether the cantonal supervisory appeal was filed in time after service by registered mail.
Extracted holding
The complaint to the cantonal higher supervisory authority was late because the seven-day pickup period had expired and service was deemed effective on 11 February 2013; the ten-day deadline ended on 21 February 2013.
Extracted reasoning
Registered mail is deemed served seven days after the unsuccessful delivery attempt regardless of the actual postal pickup period. The appellant offered no admissible basis to disprove service fiction, and new arguments about post office closure could not be considered.
