Questione giuridica chiave
Whether the employer could avoid contribution liability by alleging prior payment to another foundation.
Decisione estratta
The argument was inadequately reasoned and, in any event, the alleged payments to the other foundation did not establish exemption from the debt owed to the respondent foundation.
Motivazione estratta
The appeal failed the Federal Supreme Court's reasoning requirements and did not show why alleged payments to Fondation Z. would extinguish the separate contribution claim of Fondation Y.
