Question juridique clé
Whether Appenzell I.-Rh. courts had forum jurisdiction under Art. 59 BV after Müller left the canton before the summons was served.
Solution extraite
Yes. For personal claims, the debtor's domicile at the time the legal proceedings are initiated is decisive; a later change of domicile does not defeat jurisdiction already established by the enforcement step.
Motifs extraits
The court held that the opening of debt enforcement and the subsequent lawsuit are a continuation of the same proceeding. Since Müller was domiciled in Appenzell I.-Rh. when enforcement was initiated, he remained bound to litigate there despite later moving to Gersau, absent a waiver or lapse of the enforcement.
