Key legal question
Whether the cantonal court arbitrarily declared the nullity complaint inadmissible for lack of sufficient reasoning.
Extracted holding
No. The complaint did not meet the cantonal motivation requirements, so the refusal to examine it was not arbitrary.
Extracted reasoning
The appellant merely asserted arbitrariness without a concrete, reasoned attack; the cantonal court could rely on the strict pleading requirements of Art. 229 para. 2 CPC/VS.
