Key legal question
Whether the single-judge composition of the cantonal court was functionally competent
Extracted holding
The single judge was competent because the dispute value did not exceed the statutory threshold under cantonal procedural law.
Extracted reasoning
For minors, the previous entitlement was correctly limited to age 18 after the 4th IV revision; the revocation dispute did not raise the value above the threshold, so no referral to a three-judge panel was required.
