Batas Pambansa Bilang 22 (BP 22), popularly known as the Bouncing Checks Law, was enacted to maintain the stability of the Philippine financial system and ensure the reliability of commercial documents. It penalizes the act of making or drawing and issuing any check to apply on account or for value, knowing at the time of issue that the drawer does not have sufficient funds or credit with the drawee bank.

I. Essential Elements of the Offense

For a person to be held liable under BP 22, the prosecution must prove the following four elements beyond reasonable doubt:

The making, drawing, and issuance of any check to apply on account or for value.
The knowledge of the maker, drawer, or issuer that at the time of issue he does not have sufficient funds in or credit with the drawee bank for the payment of such check in full upon its presentment.
The subsequent dishonor of the check by the drawee bank for insufficiency of funds or credit, or dishonor for the same reason had not the drawer, without any valid cause, ordered the bank to stop payment.
The failure of the drawer to pay the amount of the check or make arrangements for its payment within five (5) banking days after receiving written notice that such check has not been paid by the drawee.

II. The Legal Presumption of Knowledge

The most critical element—knowledge of insufficiency of funds—is difficult to prove directly. Thus, Section 2 of BP 22 creates a "legal presumption."

If the check is presented within 90 days from the date of the check, the dishonor and the failure of the drawer to pay within five (5) banking days after receiving a written Notice of Dishonor serves as prima facie evidence of knowledge of insufficiency of funds. Without a written notice of dishonor served upon the drawer, the presumption does not arise, and the case will likely fail.

III. Procedural Steps for Filing

1. Presentment of the Check

The check must be presented to the bank for payment within ninety (90) days from the date indicated on the check. If the bank dishonors the check, the reason (usually "DAIF" or Drawn Against Insufficient Funds) is stamped on the back.

2. Service of Notice of Dishonor

The creditor (payee) must send a written Demand Letter/Notice of Dishonor to the debtor (drawer). This letter must:

Inform the drawer that the check was dishonored.
Demand payment for the full amount of the check.
Explicitly state that the drawer has five (5) banking days from receipt to settle the amount.
Note: Proof of receipt (e.g., registry return card or a signed received copy) is mandatory for evidence.

3. Filing the Complaint-Affidavit

If the five-day grace period expires without payment, the payee may file a Complaint-Affidavit for violation of BP 22.

Venue: The case must be filed in the Office of the Prosecutor of the city or municipality where the check was issued, signed, or dishonored.
Attachments: The original check, the return slip from the bank, the demand letter, and the proof of service/receipt.

4. Preliminary Investigation and Trial

The Prosecutor determines if there is probable cause. If found, an "Information" is filed in the Municipal Trial Court (MTC) or Metropolitan Trial Court (MeTC). Under the Revised Rules on Summary Procedure, BP 22 cases are generally tried swiftly.

IV. Penalties

Under Philippine law, the penalty for violating BP 22 is:

Imprisonment of not less than thirty (30) days but not more than one (1) year; OR
A Fine of not less than, but not more than double, the amount of the check (provided the fine does not exceed PhP 200,000.00); OR
Both fine and imprisonment at the discretion of the court.

Supreme Court Circular (No. 12-2000): The Court clarifies that while imprisonment is a penalty, judges are encouraged to prioritize the imposition of a fine if the circumstances show that the drawer did not act in bad faith or with intent to defraud. However, if the fine is not paid, "subsidiary imprisonment" may apply.

V. Important Distinctions

BP 22 vs. Estafa: BP 22 is a malum prohibitum (the act itself is a crime regardless of intent). Estafa (under the Revised Penal Code) is a malum in se and requires proof of "deceit" or "fraud" at the time of the issuance.
Civil Liability: When a criminal action for BP 22 is filed, the civil action for the recovery of the amount of the check is deemed tacitly instituted. The complainant does not need to file a separate civil case for the money.
