Key legal question
Whether the appellant had standing to challenge the closure decision because the decision's factual recitals mentioned him and his companies.
Extracted holding
He lacked a legally protected interest; the alleged harm stemmed from the earlier entry-into-force decision and was not remediable in this appeal.
Extracted reasoning
Only a direct and personal effect from the mutual assistance measure confers standing. Since the documents seized from the appellant were not transmitted and would be returned, the remaining complaint concerned only the factual summary, which was at most an indirect and already realized prejudice.
