Key legal question
Whether the complaint could be entered into despite being filed in a non-official language and not corrected after notice.
Extracted holding
The complaint was not entered into because the formal defect was not cured within the deadline.
Extracted reasoning
The filing did not comply with Art. 42(1) BGG. After notice under Art. 42(6) BGG and expiry of the cure period, the complainant did not respond. Non-entry followed under Art. 108 BGG.
