Question juridique clé
Whether the respondent could raise an incidental cross-appeal request for benefits against another pension institution.
Solution extraite
The respondent's requests seeking benefits from other institutions were inadmissible because Swiss procedural law does not provide for a cross-appeal.
Motifs extraits
The Federal Supreme Court is bound by the appellant's prayer for relief and may not go beyond it; a respondent cannot enlarge the scope by way of cross-appeal.
