Tulio vs. Atty. Buhangin

A lawyer is prohibited from representing new clients whose interests oppose those of a former client in any manner, whether or not they are parties in the same action or on totally unrelated cases.

Arthur S. Tulio engaged the services of Atty. Gregory F. Buhangin, initially as a surveyor for his mother's estate and later as legal counsel. Atty. Buhangin prepared and notarized a Deed of Waiver of Rights executed by Tulio's siblings in favor of Tulio, and subsequently represented Tulio in a specific performance case involving the property. The dispute arose when Atty. Buhangin later represented Tulio's siblings to rescind the very deed he prepared.

Arthur S. Tulio became acquainted with Atty. Gregory F. Buhangin when the latter was still a surveyor preparing plans for the estate of Tulio's mother. When Atty. Buhangin became a lawyer, Tulio sought his legal advice regarding a property owned by his mother that had been transferred to third parties. On June 29, 2000, Atty. Buhangin prepared and notarized a Deed of Waiver of Rights signed by all of Tulio's siblings in Tulio's favor. Thereafter, Tulio engaged Atty. Buhangin to represent him in a case for specific performance and damages, docketed as Civil Case No. 4866-R, before the Regional Trial Court of Baguio City. The case was eventually settled, with Tulio exclusively paying the defendants.

On December 10, 2005, Atty. Buhangin filed a complaint against Tulio on behalf of Tulio's siblings, docketed as Civil Case No. 6185-R. The complaint sought the rescission of the deed of waiver of rights that Atty. Buhangin himself had prepared and notarized. Tulio filed a motion to disqualify Atty. Buhangin, who subsequently filed a motion to withdraw as counsel, citing a conflict of interest. Tulio then filed a complaint for disbarment against Atty. Buhangin for gross dishonesty.

During the IBP investigation, Atty. Buhangin failed to attend mandatory conferences and failed to submit his position paper despite due notices. The IBP-CBD found Atty. Buhangin liable for conflict of interest and recommended a two-month suspension, which the IBP-Board of Governors approved.

• Conflict of Interest: Tulio argued that Atty. Buhangin violated his lawyer's oath and the Code of Professional Responsibility by acting as counsel for his siblings in Civil Case No. 6185-R over legal matters which he had entrusted to him.
• Misrepresentation: Tulio averred that Atty. Buhangin made misrepresentations in the complaint since he knew beforehand that his siblings waived their rights in his favor over the parcel of land covered by TCT No. 67145 even before Civil Case No. 4866-R was filed.
• Personal Representation: Tulio maintained that he personally engaged the services of Atty. Buhangin for his own benefit, as evidenced by demand letters prepared by Atty. Buhangin prior to the institution of Civil Case No. 4866-R.

• Representation of the Estate: Atty. Buhangin asserted that his legal representation was neither personal nor directed in favor of Tulio alone, but instead in the latter's capacity as an heir of Angeline Tulio.
• No Conflict of Interest: He maintained that there was no conflict of interest when he filed the complaint for the declaration of nullity of the waiver of rights, as he was merely protecting the interests of the other heirs of Angeline Tulio.
• Fraud by Complainant: Atty. Buhangin alleged that Tulio abused the confidence lodged upon him by his siblings by executing the deed of waiver of rights in his favor to deprive the other heirs of their lawful shares.

• Conflict of Interest: Whether Atty. Buhangin violated the rule on conflict of interest under Rule 15.03, Canon 15 of the Code of Professional Responsibility when he represented Tulio's siblings against Tulio.
• Administrative Liability for Disregarding IBP Orders: Whether Atty. Buhangin is administratively liable for failing to attend mandatory conferences and failing to submit his position paper before the IBP.

• Conflict of Interest: Yes. Atty. Buhangin violated Rule 15.03, Canon 15 of the Code of Professional Responsibility by representing conflicting interests.
• Administrative Liability for Disregarding IBP Orders: Yes. Atty. Buhangin's failure to comply with the IBP's orders and directives constitutes a violation of the lawyer's oath and Section 3, Rule 138 of the Rules of Court.

• Conflict of Interest: Rule 15.03 prohibits a lawyer from representing conflicting interests except by written consent of all concerned given after full disclosure. The prohibition is founded on public policy and good taste, aiming to prevent situations where a lawyer represents a client whose interest is directly adverse to a former client. In this case, Atty. Buhangin prepared and notarized a Deed of Waiver of Rights in favor of Tulio and represented Tulio in Civil Case No. 4866-R involving the same property. Later, he represented Tulio's siblings to rescind the same deed. The subject property under dispute in both cases was identical (TCT No. T-67145). Atty. Buhangin took an inconsistent position when he filed Civil Case No. 6185-R against Tulio, whom he had previously defended and protected. His subsequent withdrawal of appearance came too late, as the mere filing of the complaint manifested disloyalty and infidelity. Good faith does not make the prohibition inoperative.
• Administrative Liability for Disregarding IBP Orders: A lawyer's failure to answer the complaint and failure to appear at the investigation are evidence of flouting resistance to lawful orders of the court and illustrate a despiciency for the oath of office. Atty. Buhangin failed to attend all mandatory conferences and ignored the IBP's directive to file his position paper. This caused undue delay in the resolution of the case. As an officer of the court, he is duty-bound to comply with all lawful directives of the IBP.

• Rule on Conflict of Interest — A lawyer is prohibited from representing new clients whose interests oppose those of a former client in any manner, whether or not they are parties in the same action or on totally unrelated cases. The test is whether the lawyer's duty to fight for an issue for one client will require him to oppose it for the other client. The rule covers cases where confidential communications have been confided and those where no confidence has been bestowed. The protection given to the client is perpetual and does not cease with the termination of the litigation, nor is it affected by the party's ceasing to employ the attorney and retaining another, or by any other change of relation between them. It even survives the death of the client.
• Fiduciary Obligation of Loyalty — A lawyer owes fidelity to the cause of his client and shall be mindful of the trust and confidence reposed on him. Knowledge and information gathered in the course of the relationship must be treated as sacred and guarded with care to avoid the appearance of treachery and double-dealing.

• "There is conflict of interest when a lawyer represents inconsistent interests of two or more opposing parties. The test is 'whether or not in behalf of one client, it is the lawyer's duty to fight for an issue or claim, but it is his duty to oppose it for the other client. In brief, if he argues for one client, this argument will be opposed by him when he argues for the other client.'" — This passage defines the concept and test for conflict of interest, citing Hornilla vs. Atty. Salunat.
• "That the representation of conflicting interest is in good faith and with honest intention on the part of the lawyer does not make the prohibition inoperative." — This establishes that good faith or honest intention is not a defense against a violation of the rule on conflict of interest.
• "The protection given to the client is perpetual and does not cease with the termination of the litigation, nor is it affected by the party's ceasing to employ the attorney and retaining another, or by any other change of relation between them. It even survives the death of the client." — This articulates the perpetual nature of a lawyer's duty of fidelity and protection to a client.

• Hornilla vs. Atty. Salunat, 453 Phil. 108 (2003) — Cited to define the concept and test for conflict of interest. The Court relied on this case to establish the parameters of inconsistent representation.
• Ngayan vs. Atty. Tugade, 271 Phil. 654 (1991) — Cited to support the ruling that a lawyer's failure to answer the complaint and appear at investigation is evidence of flouting resistance to lawful orders.

• Rule 15.03, Canon 15, Code of Professional Responsibility — Prohibits a lawyer from representing conflicting interests except by written consent of all concerned given after a full disclosure of the facts. Atty. Buhangin was found guilty of violating this rule.
• Canon 17, Code of Professional Responsibility — Provides that a lawyer owes fidelity to the cause of his client and shall be mindful of the trust and confidence reposed on him. The Court used this to emphasize the perpetual duty of loyalty.
• Section 3, Rule 138, Rules of Court — Cited in relation to a lawyer's failure to answer the complaint and appear at investigation, illustrating a violation of the oath of office.
