1. No bail shall be required when the law or the Rules of Court so provide. (Rule 114, Sec. 16, Rules of Court)

2. When a person has been in custody for a period equal to or more than the possible maximum imprisonment prescribe for the offense charged, he shall be released immediately, without prejudice to the continuation of the trial or the proceedings on appeal. If the maximum penalty to which the accused may be sentenced is destierro, he shall be released after thirty (30) days of preventive imprisonment. (Rule 114, Sec. 16, Rules of Court). In these cases, the person in custody is not required to post bail prior to his release. 

3. If a complaint or information is filed directly with the Municipal Trial Court for an offense punishable by imprisonment of less four (4) years, two (2) months and one (1) day and the judge is satisfied that there is no necessity for placing the accused under custody, he may issue summons instead of a warrant of arrest (Rule 112, Sec. 8[b], Rules of Court). Bail is not required since no arrest is made. 

4. The court shall not issue a warrant of arrest for the arrest of the accused in criminal cases governed by the Rule on Summary Procedure except for railure to appear despite notice, whenever required by the court. [Sec. 4, Rule III (B), Rules on Expedited Procedures in the First Level Courts, A.M. No. 08-8-7-SC, 1 March 2022). Bail is not required since no arrest is made. 

5. Bail shall not be required of a person charged with violation of a municipal or city ordinance, a light felony and/or a criminal offense the prescribed penalty for which is not higher than six months imprisonment and/or a fine of two thousand pesos, or both, where said person has established to the satisfaction of the court or any other appropriate authority hearing his case that he is unable to post the required cash or bail bond, except in the following cases:

(a) When he is caught committing the offense in flagranti;

(b) When he confesses to the commission of the offense unless the confession is later repudiated by him in a sworn statement or in open court as having been extracted through force or intimidation;

(c) When he is found to have previously escaped from legal confinement, evaded sentence, or jumped bail;

(d) When he is found to have previously violated the provisions of Section 2 of RA 6036;

(e) When he is found to be a recidivist or a habitual delinquent or has been previously convicted for an offense to which the law or ordinance attaches an equal or greater penalty or for two or more offenses to which it attaches a lighter penalty;

(f) When he commits the offense while on parole or under conditional pardon; and

(g) When the accused has previously been pardoned by the municipal or city mayor for violation of municipal or city ordinance for at least two times (Sec. 1, R.A. 6036).

Instead of bail, the person charged shall be required to sign in the presence of two witnesses of good standing in the community a sworn statement binding himself, pending final decision of his case, to report to the Clerk of the Court hearing his case periodically every two weeks. The Court may, in its discretion and with the consent of the person charged, require further that he be placed under the custody and subject to the authority of a responsible citizen in the community who may be willing to accept the responsibility. In such a case the affidavit herein mentioned shall include a statement of the person charged that he binds himself to accept the authority of the citizen so appointed by the Court. The Clerk of Court shall immediately report the presence of the accused person to the Court. Except when his failure to report is for justifiable reasons including circumstances beyond his control to be determined by the Court, any violation of this sworn statement shall justify the Court to order his immediate arrest unless he files bail in the amount forthwith fixed by the Court (Sec. 2, R.A. 6036).
