Good info. However, I highly doubt they care about getting reports on Article 280 of the Revised Penal Code. (Article 280 is about trespassing.)
This site is horrible. The reporting feature is a sparse page with a contact form in the sidebar. The links to the reporting page are no more prominent than the Facebook share links. There's little indication the site has been touched for the last two years. I wouldn't have much faith in anyone receiving anything on the other end. Is there protocols I should be aware of? Is there legal info I should be aware of? What should I expect after submitting the contact form? What has this organization done recently? Most importantly, how do I know it's not a scam? The org itself seems to lack focus. I don't know what they are trying to accomplish. They list everything from disrupting networks to assisting in setting up counseling, safe-houses, training and a load of other stuff. I doubt their effectiveness if they can't clearly communicate their mission (and progress) on this site which might be an important tool for receiving donations. If you witness or suspect abuse, contact the local authority.
For RA 9262 you could just go to the Hall of Justice, Public Prosecutors Office and talk to one of the Assistant Prosecutors - you don't need to go through a private attorney. Just remember - no slippers / shorts allowed in Hall of Justice.
I made a report through this site and received a response. I have seen an Australian documentary about the organisation featuring reputable Australian law enforcement personnel. My guess is that it would not hurt any to register information with them. I was told the person I was concerned about not only was paying the Barangay Head and some local police, but also had guns.
The first thing to think about is evidence. Gather photos, witnesses, medical report--whatever is available--and take it to the main police station in your town. In Dumaguete, ask for the Women and Children's Desk (there is a Tagalog name for it). Get it all collected in a police report for the prosecutor.
I believe the girl's and her child's birth certificates and a court ordered DNA test for the child/father is all the evidence that a court will need.
We are talking about different laws. The ones I looked up from this thread concerned child and spousal abuse. You seem to be referencing proof of paternity. (DNA testing is not available in Dumaguete, so far as I know.)
If the girl was knocked up while she was a minor by a 76 year old man then obviously some laws were broken. Withholding child support when the old pervert is in a bad mood so that the mother and child become destitute violates the violence against women and their children law. CRBA requires a DNA test. Maybe my thought process is becoming a little more clear?
