Key legal question
Admissibility of a public law appeal against an incidental criminal evidence order
Extracted holding
The appeal was inadmissible because the challenged evidence ruling was incidental and caused no irreparable legal harm.
Extracted reasoning
Under Art. 87(2) OJ, an incidental decision is reviewable only if it can cause irreparable injury; the refusal of evidence at this investigative stage could still be remedied later, so no such prejudice existed.
