Key legal question
Whether the cantonal court could order a further medical expert assessment before deciding the disability pension claim.
Extracted holding
The cantonal court was not obviously wrong in finding the case insufficiently clarified and in requiring additional medical evidence.
Extracted reasoning
The record showed full incapacity during inflammatory flare-ups but full work capacity between flares. Given the uncertainty about frequency and duration of flare-ups, the need for further clarification was plausible and binding absent manifest error.
