This is my answer to that question given by our professor in criminal procedure when i

was in second year. i got a ten for this answer.

"As distinguished from a criminal information, a criminal complaint is subscribed by a

private party who may either be the offended party or other persons. The accusation in

the complaint is made under oath. Also, the complaint need not be filed in court. As

defined by the Rules of Court, a complaint is a sworn written statement charging a

person with an offense, subscribed by the offended party, or any peace office, or other

public officer charged with the enforcement of the law violated.

"An information, on the other hand, is defined as an accusation in writing charging a

person with an offense, subscribed by the prosecutor and filed with the court. It is

always filed in court, otherwise, it is not an information. Aside from that, it does not

include the signature of the private complainant. Only the prosecutor subscribes in the

information."

That's it. I don't know how correct it is but Judge Leopoldo Legazpi gave me a perfect

ten! He is always a generous professor... once said that what he wants to know is how

much we know and not how much we don't know.
