Question juridique clé
Whether the cantonal court had to hear the pension fund's appeal against the IV office's implementing decision of 19 May 2010.
Solution extraite
The implementing decision was a challengeable administrative decision; the cantonal court could not reject the appeal on the sole ground that no decision existed.
Motifs extraits
Although it executed a final judgment, the act had external legal effect and determined the amount and start date of pension payments, so it qualified as a decision under administrative procedure law.
