Key legal question
Whether Art. 88bis Abs. 2 lit. a IVV allows extending the one-month transition period for pension reduction or withdrawal in a hardship case.
Extracted holding
No. The regulation fixes a non-extendable one-month postponement of the effective date; the court cannot add an individual adaptation or transition period beyond that.
Extracted reasoning
The wording, legislative history, and systematics show that the revision introduced a single additional month to avoid immediate hardship. Art. 88a IVV governs when a revision is justified; Art. 88bis IVV only governs timing. Extending the deadline would contradict the purpose and structure of the rule.
