Key legal question
Whether the complaint was admissible despite available cantonal proceedings for most objections to enforcement
Extracted holding
The complaint was inadmissible for issues that could be raised in the cantonal contestation proceedings, because it was not directed against a final cantonal decision on those points.
Extracted reasoning
Under Geneva procedure, objections concerning enforceability and scope of execution had to be brought before the Tribunal de première instance; the Federal Supreme Court lacked last-instance review on those matters.
