Questão jurídica principal
Whether the appeal against the cantonal order is admissible despite being an incidental decision.
Decisão extraída
The order is an incidental decision and no irreparable legal prejudice was shown, so immediate appeal is unavailable.
Fundamentação extraída
The excluded evidence was not shown to be the sole incriminating proof, the lineup could still be repeated, and the prosecutor may seek later review against the final judgment.
