Question juridique clé
Whether Swissport had passive standing for the claim
Solution extraite
Swissport was personally bound by the 26 August 1998 letter and was therefore a proper defendant.
Motifs extraits
The letter was issued in Swissport's name, on its letterhead, and clearly promised payment by Swissport; group-internal financing and possible co-responsibility of SAirGroup did not exclude Swissport's own debt.
