Key legal question
Whether the cantonal court violated the right to be heard by relying on a substituted legal reasoning without prior notice.
Extracted holding
No violation, because the legal grounds used were reasonably foreseeable in the dispute over reconsideration and invalidity assessment.
Extracted reasoning
The parties could anticipate that the court would examine the legality of the reconsideration and the method for correcting the original pension award; no unforeseeable legal basis was introduced.
