Key legal question
Whether the constitutional complaint sufficiently challenged the cantonal decision's reasoning and alleged a constitutional violation.
Extracted holding
No. The appellants did not address the cantonal reasoning on lack of standing and did not substantiate any constitutional violation as required.
Extracted reasoning
In a constitutional complaint, the party must specifically attack the contested reasoning and show the constitutional rights violated; a mere dispute over the underlying debt or mortgage does not satisfy Arts. 116, 117 and 106(2) LTF.
