Key legal question
Whether the appellant had standing to challenge the IV decision fixing the start of the waiting period.
Extracted holding
Occupational pension institutions have a protected interest and may appeal the IV authority's determination of the start of the one-year waiting period when the insured person was obligatorily insured at the relevant time.
Extracted reasoning
The start of the waiting period usually coincides with the insured event under occupational pensions, so the pension fund may seek judicial review and appeal onward.
