Key legal question
Whether the complaint could proceed despite non-payment of the advance on costs and insufficient proof of indigence.
Extracted holding
No. The advance on costs was not paid within the grace period and the legal-aid request was not properly substantiated with sufficient evidence of financial hardship.
Extracted reasoning
Under Art. 62 BGG, the party must pay the advance on costs or validly support a legal-aid request. A grace period cannot normally be extended, and the appellant did not show exceptional unforeseen reasons justifying a further extension.
