Key legal question
Whether the appeal met the formal requirements of Art. 42 BGG, especially a sufficient statement of reasons.
Extracted holding
No. The appeal did not concretely address the contested reasoning and therefore did not satisfy the minimum requirements for a valid remedy.
Extracted reasoning
The appellant failed to engage with the cantonal court's findings, in particular on changed circumstances after re-registration and on the invalidity assessment, and did not show any violation of federal law or an obviously incorrect factual finding.
