Key legal question
Whether the appeals against the cantonal letters ordering correction of the filings were admissible without irreparable harm
Extracted holding
The challenged acts, even if treated as decisions, were incidental and caused no irreparable legal prejudice because the appellant could file corrected submissions.
Extracted reasoning
Under Art. 93(1) LTF, an incidental decision is appealable only if it causes irreparable harm. Here, the defect could be cured by resubmitting compliant pleadings.
