Key legal question
Whether the IV office committed a formal denial of justice by not deciding the objection against the 30 June 2003 refusal.
Extracted holding
The omission was a procedural defect, but it was cured in the later reapplication proceedings because the authority and the cantonal court performed a full merits review.
Extracted reasoning
A cure is possible if the later instance has full cognition and actually reviews the same merits; here the later proceedings were not limited to a mere change assessment but examined the disability claim comprehensively.
