Key legal question
Which judicial authority is competent to decide a document-freeze request under Art. 49 WPEV?
Extracted holding
Because cantonal law left a gap, the president of the tax court was provisionally competent to decide the request.
Extracted reasoning
The statutes did not expressly designate the competent judicial authority. The court filled the gap by analogy to its general competence over military substitute tax disputes and the close substantive link between those disputes and a document freeze.
