First, petitioner does not deny that what should be proved are the contents of the documents themselves. It is imperative, therefore, to submit the original documents that could prove petitioner’s allegations.
Thus, the photocopied documents are in violation Rule 130, Sec. 3 of the Rules of Court, otherwise known as the best evidence rule, which mandates that the evidence must be the original document itself. The origin of the best evidence rule can be found and traced to as early as the 18th century in Omychund v. Barker,[34] wherein the Court of Chancery said:
The judges and sages of the law have laid it down that there is but one general rule of evidence, the best that the nature of the case will admit.
The rule is, that if the writings have subscribing witnesses to them, they must be proved by those witnesses.
The first ground judges have gone upon in departing from strict rules, is an absolute strict necessity. Secondly, a presumed necessity. In the case of writings, subscribed by witnesses, if all are dead, the proof of one of their hands is sufficient to establish the deed: where an original is lost, a copy may be admitted; if no copy, then a proof by witnesses who have heard the deed, and yet it is a thing the law abhors to admit the memory of man for evidence.
Petitioner did not even attempt to provide a plausible reason why the originals were not presented, or any compelling ground why the court should admit these documents as secondary evidence absent the testimony of the witnesses who had executed them.
In particular, it may not insist that the photocopies of the documents fall under Sec. 7 of Rule 130, which states:
Evidence admissible when original document is a public record. ─ When the original of a document is in the custody of a public officer or is recorded in a public office, its contents may be proved be a certified copy issued by the public officer in custody thereof.
Secs. 19 and 20 of Rule 132 provide:
SECTION 19. Classes of documents. ─ For the purpose of their presentation in evidence, documents are either public or private.
Public documents are:
(a) The written official acts, or records of the official acts of the sovereign authority, official bodies and tribunals, and public officers, whether of the Philippines, or of a foreign country;
(b) Documents acknowledged before a notary public except last wills and testaments; and
(c) Public records, kept in the Philippines, of private documents required by law to be entered therein.
All other writings are private.
SECTION 20. Proof of private document. — Before any private document offered as authentic is received in evidence, its due execution and authenticity must be proved either:
(a) By anyone who saw the document executed or written; or
(b) By evidence of the genuineness of the signature or handwriting of the maker.
Any other private document need only be identified as that which it is claimed to be.
The fact that these documents were collected by the PCGG in the course of its investigations does not make them per se public records referred to in the quoted rule.
Petitioner presented as witness its records officer, Maria Lourdes Magno, who testified that these public and private documents had been gathered by and taken into the custody of the PCGG in the course of the Commission’s investigation of the alleged ill-gotten wealth of the Marcoses. However, given the purposes for which these documents were submitted, Magno was not a credible witness who could testify as to their contents. To reiterate, “[i]f the writings have subscribing witnesses to them, they must be proved by those witnesses.” Witnesses can testify only to those facts which are of their personal knowledge; that is, those derived from their own perception.[35] Thus, Magno could only testify as to how she obtained custody of these documents, but not as to the contents of the documents themselves.
Neither did petitioner present as witnesses the affiants of these Affidavits or Memoranda submitted to the court. Basic is the rule that, while affidavits may be considered as public documents if they are acknowledged before a notary public, these Affidavits are still classified as hearsay evidence. The reason for this rule is that they are not generally prepared by the affiant, but by another one who uses his or her own language in writing the affiant's statements, parts of which may thus be either omitted or misunderstood by the one writing them. Moreover, the adverse party is deprived of the opportunity to cross-examine the affiants. For this reason, affidavits are generally rejected for being hearsay, unless the affiants themselves are placed on the witness stand to testify thereon.[36]
As to the copy of the TSN of the proceedings before the PCGG, while it may be considered as a public document since it was taken in the course of the PCGG’s exercise of its mandate, it was not attested to by the legal custodian to be a correct copy of the original. This omission falls short of the requirement of Rule 132, Secs. 24 and 25 of the Rules of Court.[37]
In summary, we adopt the ruling of the Sandiganbayan, to wit:
Further, again contrary to the theory of the plaintiff, the presentation of the originals of the aforesaid exhibits is not validly excepted under Rule 130, Section 3 (a), (b), and (d) of the Rules of Court. Under paragraph (d), when ‘the original document is a public record in the custody of a public officer or is recorded in a public office,’ presentation of the original thereof is excepted. However, as earlier observed, all except one of the exhibits introduced by the plaintiff were not necessarily public documents. The transcript of stenographic notes (TSN) of the proceedings purportedly before the PCGG, the plaintiff’s exhibit “Q”, may be a public document, but what was presented by the plaintiff was a mere photocopy of the purported TSN. The Rules provide that when the original document is in the custody of a public officer or is recorded in a public office, its contents may be proved by a certified copy issued by the public officer in custody thereof. Exhibit “Q” was not a certified copy and it was not even signed by the stenographer who supposedly took down the proceedings.
The rest of the above-mentioned exhibits cannot likewise be excepted under paragraphs (a) and (b) of Section 3. Section 5 of the same Rule provides that ‘when the original documents has been lost or destroyed, or cannot be produced in court, the offeror, upon proof of its execution or existence and the cause of its unavailability without bad faith on his part, may prove its contents by a copy, or by a recital of its contents in some authentic document, or by the testimony of witnesses in the order stated.’ Thus, in order that secondary evidence may be admissible, there must be proof by satisfactory evidence of (1) due execution of the original; (2) loss, destruction or unavailability of all such originals and (3) reasonable diligence and good faith in the search for or attempt to produce the original. None of these requirements were complied with by the plaintiff. Similar to exhibit ‘Q’, exhibits ‘P’, ‘R’, ‘S’, and ‘T’ were all photocopies. ‘P’, ‘R’, and ‘T’ were affidavits of persons who did not testify before the Court. Exhibit ‘S’ is a letter which is clearly a private document. Not only does it not fall within the exceptions of Section 3, it is also a mere photocopy. As We previously emphasized, even if originals of these affidavits were presented, they would still be considered hearsay evidence if the affiants do not testify and identify them.[38]
Thus, absent any convincing evidence to hold otherwise, it follows that petitioner failed to prove that the Marcos siblings and Gregorio Araneta III collaborated with former President Marcos and Imelda R. Marcos and participated in the first couple’s alleged accumulation of ill-gotten wealth insofar as the specific allegations herein were concerned.
