Kernrechtsfrage
Whether the refusal to reconsider the 4 November 2003 invalidity insurance decision was judicially reviewable and whether the cantonal court applied the correct standard.
Extrahierter Entscheid
Because the administration examined the reconsideration request and refused it on the merits, the refusal was appealable; judicial review had to focus on whether the original decision was manifestly गलत and whether correction was significant.
Extrahierte Begründung
Under established social insurance law, reconsideration is discretionary, but once the administration enters into the request and decides it, the resulting refusal may be challenged. The cantonal court should therefore have examined the two cumulative reconsideration conditions.
