Key legal question
Whether the complainant had standing to challenge the cantonal decision annulling the document seizures.
Extracted holding
He lacked standing on the merits; only a claim of formal denial of justice could be reviewed.
Extracted reasoning
A complainant who is not a victim under the Victims Assistance Act and whose civil claims are not affected cannot invoke the merits of a criminal decision; he may only complain of procedural defects amounting to a formal denial of justice.
