Question juridique clé
Whether the revision request was admissible despite being filed by fax and lacking a valid signature.
Solution extraite
No. A fax submission does not satisfy the written-form and signature requirements, so the revision request could not be considered.
Motifs extraits
Art. 42(1) BGG requires a signature; the court reiterated that a fax filing is invalid and that no revision ground under Arts. 121 ff. BGG was shown.
