Key legal question
Whether the state-law constitutional complaint against the cantonal decision was admissible and could challenge the application of the Hague Evidence Convention and cantonal procedural law.
Extracted holding
The complaint was inadmissible because the challenged ruling was not a final cantonal decision on the cantonal-law issues raised, and the admissible grounds were limited to alleged violations of the Hague Convention.
Extracted reasoning
The Federal Court held that only the alleged misapplication of the Hague Evidence Convention could be reviewed freely; objections directed at the application of cantonal procedural rules and balancing of secrecy interests were not last-instance issues and thus could not be heard in this proceeding.
