"x x x.
[1] AUTER ACTION PENDANT: It refers to the situation where two actions are pending between the same parties for the same cause of action, so that one of them becomes unnecessary and vexatious. It is based on the policy against multiplicity of suits.
[2] BERRY RULE: Filing of motion for new trial based on newly discovered evidence which cannot be produced in court despite exercise of due diligence, and if considered would probably alter the outcome of the case.
[3] BUBBLE BURST THEORY: The rule on presumption of law shall not apply in case there is evidence to the contrary.
[4] CHAIN OF CUSTODY: Is "the duly recorded authorized movements and custody of seized drugs or controlled chemicals or plant sources of dangerous drugs or laboratory equipment of each stage, from the time of seizure/confiscation to receipt in the forensic laboratory to safekeeping to presentation in court for destruction." (see also: People vs. Alivio, G.R. No. 177771, May 30, 2011).
[5] CONTINUING THREAT: In order that writ of amparo can be issued, the threat on the right to life liberty or security must be actual and continuing and not merely imaginary, thereby depriving the petitioner of his said right from the inception up to the termination of the case.
[6] FALSA DEMONSTRATIO NON NOCET: It is a rule which states that where there are two descriptions in a deed, the one as it were, super added to the other, and one description being complete and sufficient in itself, and the other which is subordinate and super added is incorrect, the incorrect description or feature or circumstance of the description is rejected as a surplusage, and the complete and correct description is allowed to stand alone. (Please see: Myers vs. Ladd, 26 Ill, 515, 417)
[7] FRESH PERIOD: It is a procedural law as it prescribes a fresh period of 15 days within which an appeal may be made in the event that the motion for reconsideration is denied by the lower court. Following the rule on retroactivity of procedural laws, the “fresh period rule” should be applied to pending actions, such as the present case. (Priscilla Alma Jose vs. Ramon Javellana, et al., G.R. No. 158239, January 25, 2012)

[9] HYPOTHETICAL ADMISSION or PRESUMPTION OF TRUTH: When a motion to dismiss is filed, the material allegations of the complaint are deemed to be hypothetically admitted. This hypothetical admission, extends not only from the relevant and material facts well pleaded in the complaint, but also to inferences that may be fairly deduced from them. (The Municipality of Hagonoy, Bulcan, et al. vs. Hon. Simeon Dumdum, Jr., G.R. No. 168289, March 22, 2010)
[10] IMMUTABILITY OF JUDGMENT: Once the judgment becomes final and executory, it can no longer be amended, set aside, or disturbed
[11] INDEPENDENT RELEVANT STATEMENT: Regardless of the truth or falsity of a statement, when what is relevant is the fact that such statement has been made, the hearsay rule does not apply and the statement may be shown.

[12] INTERLOCKING CONFESSION: These are extrajudicial confessions which were independently made without collusion, are identical with each other in their material respects and confirmatory of the other. They are, therefore, also admissible as circumstantial evidence against their co-accused implicated therein to show the probability of the latter’s actual participation in the commission of the crime.
[13] JUDICIAL COURTESY: “[d]ue respect for the Supreme Court and practical and ethical considerations should have prompted the appellate court wait for the final determination of the petition [for certiorari] before taking cognizance of the case and trying to render moot exactly what was before this [C]ourt.” The principle of judicial courtesy applies only “if there is a strong probability that the issues before the higher court would be rendered moot and moribund as a result of the continuation of the proceedings in the lower court.”(Juan Trajano aka Johnny vs. Uniwide Sales Warehouse ClubG.R. 190253, June 11, 2014)
[14] LAW OF THE CASE: It has been defined as the opinion delivered on a former appeal, and means, more specifically, that whatever is once irrevocably established as the controlling legal rule of decision between the same parties in the same case continues to be the law of the case, whether correct on general principles or not, so long as the facts on which such decision was predicated continue to be the facts of the case before the court.
[15] MATERIAL DATES: Under the material dates rule, a petition must alleged three (3) material dates which is necessary which are as follows: 1) The date when the judgment or final order or resolution was received; 2) The date when the motion for reconsideration or new trial was filed; and 3) The date when the notice of the denial thereof was received. (Great Southern Maritime Services Corporation vs. Acuna, 452 SCRA 422, February 28, 2005)
[16] NON-PROSEQUITUR: Once a case is dismissed for failure to prosecute, the dismissal has the effect of an adjudication on the merits and is understood to be with prejudice to the filing of another action unless otherwise provided in the order of dismissal.
[17] NON-SUITED: Failure of the plaintiff to appear on the scheduled pre-trial conference would result to the dismissal of the case with prejudice, unless otherwise ordered by the court to be without prejudice.
[18] PARTY AUTONOMY: Parties have the freedom to expressly stipulate or agree by virtue of written agreement on how their disputes will be settled by submitting their differences to an arbitrator before an action may be commenced in court.
[19] PRESUMED IDENTITY APPROACH: Where a foreign law is not pleaded or, even if pleaded, is not proved, the presumption is that foreign law is the same as ours. (ATCI Overseas Corporation, Amalia G. Ikdal And Ministry Of Public Health-Kuwait Vs. Ma. JosefaEchin, G.R. No. 178551, October 11, 2010)
[20] PRIMARY JURISDICTION: When an administrative body is clothed with original and exclusive jurisdiction, courts are utterly without power and authority to exercise concurrently such jurisdiction. Accordingly, all the proceedings of the court in violation of that doctrine and all orders and decisions reached are null and void. (Manolito Agra, et al., vs. Commission on Audit, G.R. No. 167807, December 6, 2011)
[21] RECOUPMENT: A compulsory counterclaim arises out of or is connected with the transaction or occurrence constituting the subject matter of the opposing party’s claim which does not require the presence of a third person over whom the court cannot acquired jurisdiction;
[22] RELAXED ADMISSIBILITY OF EVIDENCE : In the proper resolution of the case, the court has the discretion to admit a rather inadmissible evidence provided it has a relation to other evidence already presented which is relevant to the fact in issue in the case.

[24] SET-OFF: A permissive counterclaim does not arise out of and is not connected with the transaction or occurrence constituting the subject matter of the opposing party’s claim which required the presence of a third person for its adjudication;
[25] SEXUAL ABUSE SHIELD: The following evidence is not admissible in any criminal proceeding involving alleged child sexual abuse: (1) Evidence offered to prove that the alleged victim engaged in other sexual behavior; and(2) Evidence offered to prove the sexual predisposition of the alleged victim. (b) Exception.— Evidence of specific instances of sexual behavior by the alleged victim to prove that a person other than the accused was the source of semen, injury, or other physical evidence shall be admissible.
[26] STATUTE OF NON-CLAIMS: Immediately after granting letters testamentary or administration, the court shall issue a notice requiring all persons having money claims against the decedent to file them in the office of the clerk of court which shall state the time of the filing of the claim against estate, which shall not be more than twelve (12) months but less than six (6) months after the date of first publication of the notice, but before distribution is entered, upon application of an unpaid creditor who failed to file his claim, the court on cause shown may allow the claim to be filed within the time not exceeding one (10 month.
[27] STRONG ARM OF EQUITY: At times referred to as the “Strong Arm of Equity,” [the Court has] consistently ruled that there is no power the exercise of which is more delicate and which calls for greater circumspection than the issuance of an injunction. It should only be extended in cases of great injury where courts of law cannot afford an adequate or commensurate remedy in damages; “in cases of extreme urgency; where the right is very clear; where considerations of relative inconvenience bear strongly in complainant’s favor; where there is a willful and unlawful invasion of plaintiff’s right against his protest and remonstrance, the injury being a continuing one, and where the effect of the mandatory injunction is rather to re-establish and maintain a pre-existing continuing relation between the parties, recently and arbitrarily interrupted by the defendant, than to establish a new relation.”(Thunder Security and Investigation Agency vs. National Food Authority, supra)
[28] TRANSCENDENTAL IMPORTANCE: Suspension of the rules of procedure in case the subject matter of the action is of great importance/involving national interest;
[29] TWO-DISMISSAL: When the notice operates as an adjudication upon the merits when filed by a plaintiff who has once dismissed in a competent court an action based on or including the same claim.

The right is available only in CIVIL cases.
