Questione giuridica chiave
Whether revision under Art. 123(2)(a) BGG was admissible on the basis of a post-judgment letter and alleged deception/fundamental mistake.
Decisione estratta
Revision is available only for after-discovered facts or evidence not arising after the judgment; the 24 November 2012 letter was a true nova and therefore inadmissible. The alleged deception and fundamental mistake were not proven.
Motivazione estratta
Art. 123(2)(a) BGG excludes facts and evidence created only after the challenged decision. The applicant failed to show that the respondent had already planned the later termination when the supplement was signed, and the separate drafting of the documents did not prove deception.
