Questão jurídica principal
Whether the public-law appeal against the interlocutory decision refusing evidence was admissible under Art. 87 OG.
Decisão extraída
The decision was an interlocutory ruling; because no irreparable legal prejudice was shown, the appeal was not admissible at this stage.
Fundamentação extraída
Refusals of evidence in criminal proceedings generally do not cause irreparable legal harm, since any procedural defect can be raised later against the final judgment. The appellant failed to show a concrete risk of loss of evidence.
