Explain exclusionary rule

Default modelResearch answer

In short

The exclusionary rule is a constitutional rule that makes certain evidence inadmissible in court when it was obtained in violation of the constitutional protections against unreasonable searches and seizures or unlawful privacy intrusions.

Explanation

Step 1: Check whether the evidence was obtained in violation of the constitutional protections covered by Article III. (1987 Constitution, Article III, Sections 2 and 3)
Step 2: If the evidence was obtained in violation, treat it as inadmissible “for any purpose” in “any proceeding.” (1987 Constitution, Article III, Section 3)
Step 3: Even if the evidence is relevant, it still cannot be admitted if it is “excluded by the Constitution.” (Rules of Evidence, Rule 128, Section 3)
Step 4: In court cases covered by the exclusionary rule, the excluded evidence cannot be used, and depending on whether it is essential to the charge, the case may fail and result in acquittal. (People of the Philippines v. Gardon-Mentoy, G.R. No. 223140)

“Any evidence obtained in violation of this or the preceding section shall be inadmissible for any purpose in any proceeding.”

1987 Constitution, Article III, Section 3

This means that if evidence is obtained in violation of the constitutional rules on unreasonable searches and seizures or on privacy of communication and correspondence, the evidence cannot be used at all in any court case.

“The right of the people to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures of whatever nature and for any purpose shall be inviolable, and no search warrant or warrant of arrest shall issue except upon probable cause to be determined personally by the judge after examination under oath or affirmation of the complainant and the witnesses he may produce, and particularly describing the place to be searched and the persons or things to be seized.”

1987 Constitution, Article III, Section 2

This sets the constitutional standard for when a search warrant or arrest warrant may issue, so evidence obtained without meeting that standard can trigger the exclusionary rule.

“Any evidence obtained in violation of this or the preceding section shall be inadmissible for any purpose in any proceeding.”

1987 Constitution, Article III, Section 3

This also applies when the violation is in the preceding section that deals with unreasonable searches and seizures, not only when the violation is in the section on privacy of communications.

“Evidence is admissible when it is relevant to the issue and not excluded by the Constitution, the law or these Rules.”

Rules of Evidence, Rule 128, Section 3

This explains how evidence rules work generally: evidence must be relevant, and it must also not be blocked by the Constitution, including the exclusionary rule.

In short

The exclusionary rule is a constitutional rule that makes certain evidence inadmissible in court when it was obtained in violation of constitutional protections, such as those against unreasonable searches and seizures and unlawful violations of privacy, communications, or related rights.

Explanation

The exclusionary rule works by blocking evidence from being used in court if it was obtained in violation of the Constitution’s protected rights, including the rights against unreasonable searches and seizures and unlawful privacy intrusions. (Article III, Section 3; Article III, Section 2; Rule 128, Section 3, Revised Rules on Evidence)
Even if evidence is relevant, it can still be excluded if the Constitution or the law says it cannot be used. (Rule 128, Section 3, Revised Rules on Evidence)
For privacy and communications, evidence obtained in violation of the constitutional privacy protection is inadmissible for any purpose in any proceeding. (Article III, Section 3)
For investigations and statements, confessions or admissions obtained in violation of the constitutional protections described in the investigation rights section (and linked to self-incrimination protections) are inadmissible against the person. (Article III, Section 12; Article III, Section 17)
A warrantless search is sometimes allowed only within strict limits, such as when there is a lawful arrest first, and the search is for dangerous weapons or anything used or that proves an offense. (Rule 126, Section 13, Rules of Court)
If a search is justified only by something like an unverified tip, and there are no other circumstances establishing probable cause, the justification fails. (People of the Philippines v. Gardon-Mentoy, G.R. No. 223140 (2019-09-04))
If the arrest does not precede the search, the search cannot be justified as a search incident to arrest, and evidence from that invalid search should be excluded. (People of the Philippines v. Gardon-Mentoy, G.R. No. 223140 (2019-09-04))

"Evidence is admissible when it is relevant to the issue and not excluded by the Constitution, the law or these Rules. (3a)"

Revised Rules on Evidence, Section 3

"The privacy of communication and correspondence shall be inviolable except upon lawful order of the court, or when public safety or order requires otherwise, as prescribed by law. Any evidence obtained in violation of this or the preceding section shall be inadmissible for any purpose in any proceeding."

The 1987 Constitution of the Republic of the Philippines, Section 3

A search without a warrant can be allowed only when there is a lawful arrest first, and the search is limited to dangerous weapons or proof tied to an offense, as provided by law.

“Evidence is admissible when it is relevant to the issue and not excluded by the Constitution, the law or these Rules.”

Rule 128, Section 3, Revised Rules on Evidence

This means relevant evidence still must be rejected if the Constitution (including the exclusionary rule) says it cannot be used.

“The right of the people to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures of whatever nature and for any purpose shall be inviolable, and no search warrant or warrant of arrest shall issue except upon probable cause to be determined personally by the judge after examination under oath or affirmation of the complainant and the witnesses he may produce, and particularly describing the place to be searched and the persons or things to be seized.”

Article III, Section 2, The 1987 Constitution of the Republic of the Philippines

This sets the protection against unreasonable searches and seizures and requires judicial warrants supported by personal determination of probable cause, with specific details about what will be searched and seized.

“The privacy of communication and correspondence shall be inviolable except upon lawful order of the court, or when public safety or order requires otherwise, as prescribed by law. Any evidence obtained in violation of this or the preceding section shall be inadmissible for any purpose in any proceeding.”

Article III, Section 3, The 1987 Constitution of the Republic of the Philippines

This is one direct statement of the exclusionary rule: evidence taken in violation of privacy of communication and correspondence (or the related preceding right) cannot be used for any purpose in any proceeding.

“Any person under investigation for the commission of an offense shall have the right to be informed of his right to remain silent and to have competent and independent counsel preferably of his own choice. If the person cannot afford the services of counsel, he must be provided with one. These rights cannot be waived except in writing and in the presence of counsel.”

Article III, Section 12, The 1987 Constitution of the Republic of the Philippines

This protects the right to remain silent and the right to counsel during investigations, which helps set limits on how admissions or confessions may be obtained.

“Any confession or admission obtained in violation of this or Section 17 hereof shall be inadmissible in evidence against him.”

Article III, Section 12, The 1987 Constitution of the Republic of the Philippines

This applies the exclusionary rule to confessions or admissions taken in violation of the constitutional protections mentioned in that section.

“No person shall be compelled to be a witness against himself.”

Article III, Section 17, The 1987 Constitution of the Republic of the Philippines

This is the constitutional right against self-incrimination, which supports excluding compelled statements.

Section 2, The 1987 Constitution of the Republic of the Philippines
Section 3, Revised Rules on Evidence
Section 3, The 1987 Constitution of the Republic of the Philippines
Section 12, The 1987 Constitution of the Republic of the Philippines
Section 17, The 1987 Constitution of the Republic of the Philippines

The Constitution provides that any evidence obtained in violation of the privacy of communication and correspondence or the right against unreasonable searches and seizures shall be inadmissible for any purpose in any proceeding (Article III, Section 3, The 1987 Constitution of the Republic of the Philippines).

“The exclusionary rule is intended to deter the violation of the right to be protected from unreasonable searches and arrest.”

People of the Philippines v. Gardon-Mentoy, G.R. No. 223140 (2019-09-04)

This explains the purpose: courts exclude such evidence to discourage violations of the rights protected by the Constitution.

“In short, the tip, in the absence of other circumstances that would confirm their suspicion coming to. the knowledge of the searching or arresting officer, was not yet actionable for purposes of effecting an arrest or conducting a search.”

People of the Philippines v. Gardon-Mentoy, G.R. No. 223140 (2019-09-04)

This settles that evidence obtained from a search cannot be justified only by an unverified tip, without independent circumstances that establish probable cause for the arrest or search.

“The arrest of the accused-appellant did not justify the search of the personal belongings because the arrest did not precede the search.”

People of the Philippines v. Gardon-Mentoy, G.R. No. 223140 (2019-09-04)

This holds that the warrantless search of personal belongings cannot be justified as a search incident to a lawful arrest if the arrest did not come first.

“Accordingly, there should first be a lawful arrest before the warrantless search can be made; the process cannot be reversed.”

People of the Philippines v. Gardon-Mentoy, G.R. No. 223140 (2019-09-04)

This settles the timing requirement for a warrantless search tied to arrest: the lawful arrest must come before the search.

The Supreme Court explained that when a warrantless search is conducted without sufficient probable cause, the search is considered unreasonable and the resulting evidence is invalidated (People of the Philippines v. Gardon-Mentoy, G.R. No. 223140 (2019-09-04)).
