G.R. No. 13300 - Bough vs. Cantiveros

The suit was initiated in the Court of First Instance of Leyte by Basilia Bough and Gustavus Bough, who sought possession of property allegedly transferred by a deed of sale.
The plaintiffs additionally claimed damages of five hundred pesos and costs against the defendant, Matilde Cantiveros.
Matilde Cantiveros answered with both a general denial and a special (but unsworn) defense, asserting that the contract of sale was null.
Presbitera Hanopol intervened as a defendant in the case.
After trial, Judge W. E. McMahon rendered judgment in favor of the defendants, declaring the deed of sale (Exhibit A) fictitious, null, and without effect, and absolving the defendants from the relief sought by the plaintiffs, with costs ordered against the plaintiffs.

Matilde Cantiveros was known as the richest resident of Carigara, Leyte, owning various parcels of real estate valued at thirty thousand pesos or more.
On December 24, 1912, Matilde Cantiveros and her husband, Jose Vasquez, executed a marital contract of separation.
Basilia Hanopol, a cousin and long-time protege of Matilde, lived with her; Basilia was married to Gustavus Bough, who was treated by Matilde almost as a child.
Gustavus Bough exerted considerable influence over Matilde, contributing to the creation of the fraudulent transaction.

Influenced by Gustavus Bough’s suggestion that her husband might challenge the separation agreement, Matilde Cantiveros was induced to sign a fictitious contract of sale (Exhibit A) whereby she purported to sell 63 parcels of land—whose real value exceeded thirty thousand pesos—for the sum of ten thousand pesos.
No evidence was introduced to show that the ten thousand pesos had actually been exchanged.
To allay Matilde’s fears of exploitation, Basilia Bough and Gustavus Bough executed a separate document (Exhibit 1) which purported to serve as a donation in favor of Matilde, effective upon the death of themselves and their children.

Under Section 103 of the Philippine Code of Civil Procedure, the genuineness and due execution of a written instrument is presumed admitted if not specifically denied under oath.
The plaintiffs failed to corroborate their declarations concerning the document, whereas the defendants’ version was supported by reliable witnesses.
The defendants were permitted to introduce evidence regarding the circumstances under which Exhibit A was executed, including allegations of fraud, mistake, and absence of consideration, without being barred by the procedural presumptions regarding written instruments.

Whether the trial court erred in allowing the defendants to introduce evidence aimed at impugning the genuineness and due execution of Exhibit A despite the absence of a sworn denial.
Whether the evidence regarding the circumstances of the execution of the document (i.e., fraud and misrepresentation) was properly admitted in view of Section 103 and Section 285 of the Code of Civil Procedure.

Whether the demonstration of fraud and wrong-doing in the execution of Exhibit A suffices to render the transaction illegal and void.
Whether the existence of the separate donation instrument (Exhibit 1) creates an estoppel that would prevent Matilde Cantiveros from denying the lack of consideration contained in Exhibit A.

Whether enforcing the fraudulent contract, even in part, would contravene established doctrines of public policy regarding contracts induced by fraud.
How principles such as “ex dolo malo non oritur actio” and “in pari delicto potior est conditio defendentis” apply in a case where one party is not equally complicit in the fraud.
