Key legal question
Whether judicial costs should be charged for the cantonal social-insurance appeal proceedings after remand.
Extracted holding
No judicial costs were charged, because the AI office as a public authority is exempt from procedural costs.
Extracted reasoning
Although AI appeals concerning benefits are in principle subject to court costs, the cantonal procedural rules bar costs against the Confederation and the State, and this exemption extends to cantonal AI offices performing public-law tasks.
