Questione giuridica chiave
When can a disability-attendance allowance claim first arise under Art. 42(4) IVG?
Decisione estratta
The claim does not depend on Art. 29(1) IVG; the relevant timing follows Art. 28(1) IVG by analogy, so the lower court's interpretation was wrong.
Motivazione estratta
The wording of Art. 42(4) IVG suggests a reference to Art. 29(1) IVG, but the legislative history, purpose of the 5th IV revision, and the conceptual difference between disability and helplessness show that this reference does not reflect the legislature's true intent.
