Whether the public prosecutor lawfully refused to enter into the complaint under Art. 310 CPP
Yes. The record did not show any concrete indication that the witness's testimony was false, and further investigations would not have produced decisive additional evidence.
The court found the witness credible: she had not authored the prior written declaration, had limited French, had directly observed the disputed exchange, and had not attempted to incriminate the complainant. On that basis, a conviction for false testimony or an honour offence was manifestly excluded.
