Questão jurídica principal
Whether the appellant was entitled to challenge the disclosure of all requested materials and invoke Art. 2 lit. a IRSG based on alleged ECHR violations in the Finnish proceedings.
Decisão extraída
He lacked standing for measures not directly affecting him, and as a third party he could not invoke the accused person's defence rights; Art. 2 lit. a IRSG did not bar assistance here.
Fundamentação extraída
Only persons personally and directly affected may appeal. Third parties may not raise the accused's procedural rights vicariously. Where the treaty requirements are met, Art. 2 lit. a IRSG generally cannot defeat assistance.
