Question juridique clé
Whether a later change in Federal Supreme Court case law constitutes a revision ground under Art. 123(2)(a) BGG.
Solution extraite
No. Revision under Art. 123(2)(a) BGG is limited to previously existing but newly discovered facts or evidence; a subsequent change in legal case law is not a revision ground.
Motifs extraits
The provision concerns novae in fact or evidence, not legal reassessments. A practice change is a new legal evaluation, not a new fact, and the former OG practice remains applicable under the BGG.
