OBJECTION AT TRIAL NO. 11:
THE QUESTION IS SELF-INCRIMINATORY!
By Atty. Florante A. Zagada.
FORM OF OBJECTION:
[At sidebar] The question is one that the witness cannot be compelled to answer because of the privilege against self-incrimination, which is hereby invoked.
RESPONSE:
Opposing counsel should demand an offer of proof on the validity of the claim of privilege.
Where the trial court determines the requested evidence would tend to incriminate the witness, there is no response since the privilege is absolute.
COMMENTARY:
We oftentimes hear this right in courtroom dramas. We would hear a witness utter, “I invoke the right to remain silent!” or “I invoke the right against self-incrimination!”.
THE LEGAL MEANING.
The right against self-incrimination is found in Art. III, Sec. 17 of the 1987 Philippine Constitution, which states that
“No person shall be compelled to be a witness against himself.”
This right, as put by Mr. Justice Holmes in Holt vs. United States, ". . . is a prohibition of the use of physical or moral compulsion, to EXTORT COMMUNICATIONS from him . . ." It is simply a prohibition against legal process to extract from the [accused]'s OWN LIPS, against his will, admission of his guilt.
The Fifth Amendment provides that “[n]o person . . . shall be compelled in any criminal case to be a witness against himself.” U.S. Const. Amend. V. The privilege generally is not self-executing and a witness who desires its protection must claim it. Salinas v. Texas, 570 U.S. 178, 133 S.Ct. 2174, 186 L.Ed.2d 376 (2013); U.S. v. Medunjanin, 752 F.3d 576 (2d Cir. 2014).
The privilege may be invoked not only at trial but also at the pleading stage and in the course of discovery proceedings. Nutramax Laboratories, Inc. v.Twin Laboratories, Inc., 32 F.Supp. 2d 331 (D. Md. 1999).
It can be asserted in any proceeding, whether civil, criminal, administrative, or investigatory (including a grand jury) in which the witness reasonably believes that the information sought, or the evidence discovered as a result of that information, could be used against him in a subsequent criminal proceeding. Lefkowitz v. Turley, 414 U.S. 70, 94 S.Ct. 316, 38 L. Ed. 2d 274
BASIS OF THIS RIGHT.
This is based on the grounds of public policy and humanity—of policy, because if the party were required to testify, it would place the witness under the strongest temptation to commit the crime of perjury, and of humanity, because it would prevent the extorting of confessions by duress [U.S. vs. Navarro, G.R. No. 1272, 11 January 1904].
SCOPE AND COVERAGE OF THIS RIGHT.
1. CRIMINAL PROCEEDINGS.
The right against self-incrimination primarily applies to criminal cases. The accused cannot be compelled to testify or produce evidence that could incriminate him. This protects the accused from being placed in a situation where he might be forced to choose between lying (and thus committing perjury) or confessing guilt.
If the accused chooses to testify, however, he waives this right regarding matters on which he testifies. He may then be cross-examined on these matters.
The protection applies from the moment a person becomes a suspect or is subjected to custodial investigation, continuing through trial and other legal proceedings.
2. CUSTODIAL INVESTIGATION:
During custodial investigation, under Section 12(1) of the Constitution, an individual must be informed of the right to remain silent and to have competent and independent counsel. This supplements the right against self-incrimination, ensuring that individuals cannot be compelled to admit guilt through coerced confessions.In the absence of these rights being observed (such as failure to provide a lawyer), any admission made during custodial investigation is inadmissible as evidence against the accused.
3. NON-CRIMINAL PROCEEDINGS.
Although primarily a protection in criminal cases, the right against self-incrimination also applies to civil, administrative, or legislative proceedings, but with limitations. In these proceedings, a person may refuse to answer specific questions that may tend to incriminate them in a criminal case.
For witnesses in non-criminal proceedings (including civil, administrative, or legislative hearings), the right may only be invoked on a question-by-question basis. The witness cannot refuse to testify entirely but may refuse to answer specific questions that might tend to incriminate them.
4. LEGISLATIVE INQUIRIES.
Inquiries in aid of legislation conducted by Congress (Senate or House of Representatives) can compel a witness to testify, but the witness retains the right to refuse to answer questions that would self-incriminate.
Contempt or other penalties cannot be imposed on a witness invoking the right, provided there is reasonable ground to fear self-incrimination.
Congress has no power to grant immunity, but it may request the President or the Department of Justice to grant statutory immunity to a witness, thus compelling testimony without the risk of prosecution.
WHEN THIS RIGHT CANNOT BE INVOKED.
1. COMPULSORY PRODUCTION OF PHYSICAL EVIDENCE.
The right against self-incrimination does not extend to the production of physical evidence, such as fingerprints, handwriting samples, or photographs. A person may be compelled to provide non-testimonial evidence, provided it does not require mental processes or disclosure of incriminating information.
The Supreme Court in the case of People v. Olvis and Villaflor v. Summers, held that the right against self-incrimination applies to testimonial evidence and not to physical or mechanical acts.
2. WHEN THIS RIGHT IS WAIVED BY THE ACCUSED OR WITNESS.
The right against self-incrimination can be waived, either explicitly or implicitly. For example, when an accused voluntarily takes the stand in his defense, he opens himself up to cross-examination on the matters he testifies to.
3. CORPORATION AND OTHER ENTITIES.
The right against self-incrimination is a personal right and applies only to natural persons, not to juridical entities like corporations or partnerships. Corporate officers, employees, or representatives may not invoke the right on behalf of the corporation, though they may invoke it to protect themselves personally.
TWO ASPECTS OF THIS RIGHT.
1.THE RIGHT TO REFUSE TO TAKE THE WITNESS STAND.
This right, the right to refuse to take the witness stand, is available only to an accused in a criminal case. Thus, an accused, cannot be compelled, even through a subpoena or court order, to testify and be a witness. Kindly note that in certain administrative investigations that are similar to adversary proceedings or partake of a nature of a criminal proceeding, the Supreme Court has allowed the party to invoke the right akin to that of an accused. In Cabal vs. Kapunan [G.R. No. L-19052, 29 December 1962], the right was made available to a person charged administratively for graft because of the nature of the penalty that may be imposed by the administrative body; the hearing partakes of the nature of a criminal proceeding.
The same right was accorded to a person charged before a Board of Medical Examiners for alleged immorality in the case of Pascual vs. Board of Medical Examiners [G.R. No. L-25018, 26 May 1969] because the person’s license is at stake.
2. RIGHT TO REFUSE INCRIMINATORY QUESTION.
This is available to both the accused and any witness. In Rosete vs. Lim [G.R. No. 136051, 08 June 2006], the Supreme Court ruled that this right “secures to a witness, whether he be a party or not, the right to refuse to answer any particular incriminatory question, i.e., one the answer to which has a tendency to incriminate him for some crime. However, the right can be claimed only when the specific question, incriminatory in character, is actually put to the witness. It cannot be claimed at any other time.
This right does not give a witness the right to disregard a subpoena, decline to appear before the court at the time appointed, or refuse to testify altogether. The witness receiving a subpoena must obey it, appear as required, take the stand, be sworn, and answer questions.” This right may be waived. If not claimed by or on behalf of the witness, the protection does not come into play [People vs. Ayson, G.R. No. 85215, 07 July 1989].
The right against self-incrimination applies only to testimonial compulsion.
