Key legal question
Which pension institution is liable for disability benefits when incapacity and invalidity span several affiliations?
Extracted holding
Liability depends not only on the institution with which the insured was affiliated when incapacity for work began, but also on whether there is a close material and temporal connection between that incapacity and the later invalidity.
Extracted reasoning
A short remission does not interrupt the temporal link. Here, the six months of full-time work, followed by six months of unemployment and six months of part-time work, were treated as only a brief remission of the illness, so the same institution remained liable.
