What Is Preliminary Investigation in the Philippines?

A preliminary investigation is a critical stage in Philippine criminal procedure. It is the process conducted by a prosecutor to determine whether a criminal case should be filed in court. Contrary to popular belief, it is not a trial and does not decide guilt or innocence. Instead, it acts as a legal filter to ensure that only cases supported by sufficient evidence proceed to trial.

Understanding what a preliminary investigation is essential for both complainants and respondents in criminal cases.
