Key legal question
Whether the non-lieu for assault and insult should be overturned and the accused sent for trial.
Extracted holding
The available evidence did not allow one version of the facts to be preferred; the accused benefited from the doubt and no further investigation was useful.
Extracted reasoning
The witness evidence was of limited probative value, the accused's alibi was not conclusively disproved, and in dubio pro reo justified ending the investigation.
