Key legal question
Whether the reduction of an existing child-support contribution due to changed circumstances must be decided by a court or by administrative authorities.
Extracted holding
The court is competent; the Vormundschaftskommission, Gemeinderat, and Regierungsrat lack jurisdiction.
Extracted reasoning
Claims for child support and later modification of maintenance are governed by the ZGB and must be judicially decided. Under the cantonal implementing ordinance, the Kantonsgerichtspräsident has jurisdiction for changes in circumstances, subject to appeal to the Obergerichtspräsident. Because the jurisdictional allocation is clear, administrative authorities cannot examine the merits.
