Cabugao vs. People

Reckless imprudence resulting in homicide requires proof beyond reasonable doubt of an inexcusable lack of precaution measured by the standard of care of a reasonably competent physician under similar circumstances; a general practitioner who refers a suspected appendicitis patient to a surgeon and continues monitoring is not criminally liable, and conspiracy is inconsistent with a felony committed by culpa. Death of the accused pending appeal extinguishes criminal liability and civil liability based solely on delict, but civil liability arising from contract or quasi-delict survives against the estate.

Dr. Antonio P. Cabugao was a general practitioner specializing in family medicine, and Dr. Clenio Ynzon was a surgeon. They were the attending physicians of Rodolfo Palma, Jr., the ten-year-old son of Spouses Rodolfo M. Palma and Rosario F. Palma. The prosecution charged them under Article 365 of the Revised Penal Code for reckless imprudence resulting in homicide, a quasi-offense requiring proof of an inexcusable lack of precaution. The case reached the Supreme Court through consolidated appeals from the Court of Appeals.

On June 14, 2000, at around 4:00 p.m., ten-year-old Rodolfo F. Palma, Jr. (JR) complained of abdominal pain to his mother, Rosario Palma. At 5:00 p.m. that same afternoon, Rosario and Atty. Rodolfo Palma, Sr. brought JR to the clinic of Dr. Antonio P. Cabugao. Dr. Cabugao, a general practitioner specializing in family medicine, gave medicines for the pain and told the parents to call him if the stomach pains continued. Because the abdominal pains persisted, at 4:30 a.m. on June 15, 2000, they returned to Dr. Cabugao, who advised them to bring JR to Nazareth General Hospital in Dagupan City for confinement. JR was admitted at 5:30 a.m.

Blood samples were taken for laboratory testing. The complete blood count showed wbc – 27.80 x 10 9/L; lymphocytes – 0.10; and neutrophils – 0.90. A diagnostic ultrasound of JR’s lower abdomen, performed by radiologist Dr. Ricky V. Querubin, found a normal liver, bile ducts, gallbladder, pancreas, spleen, kidneys, and urinary bladder; no free peritoneal fluid; localized tenderness in the paraumbilical region, more so in the supra and right paraumbilical areas; and a vague elongated hypoechoic focus in the right periumbilical region roughly 47 x 18 mm surrounded by undistended gas-filled bowels, suggestive of an inflammatory process wherein appendiceal or periappendiceal pathology cannot be excluded, with clinical correlation essential. Dr. Cabugao performed a rectal examination noting good sphincter, negative tenderness, and negative mass. The initial impression was acute appendicitis, and he referred the case to Dr. Clenio Ynzon, a surgeon.

In the later part of the morning of June 15, 2000, Dr. Ynzon went to the hospital and read the CBC and ultrasound results. He ordered the administration of massive antibiotics and pain reliever, and JR was placed on observation for twenty-four hours. In the morning of June 16, 2000, JR again complained of abdominal pain, and his parents noticed a swelling in his scrotum. In the afternoon of that same day, JR vomited greenish stuff three times and had watery bowels three times. The nurses on duty relayed JR’s condition to Dr. Ynzon, who merely gave orders via telephone. The accused continued medications to alleviate JR’s abdominal spasms and diarrhea. During the monitoring period, Dr. Cabugao frequently made orders on the administration of antibiotics and pain relievers and repeatedly instructed that JR be referred to Dr. Ynzon as he suspected appendicitis. By midnight, JR again vomited twice, had loose bowel movements, and was unable to sleep.

In the morning of June 17, 2000, JR’s condition worsened; he had a running fever of 38°C. His fever remained uncontrolled and he became unconscious, and he was given Aeknil (1 ampule) and Valium (1 ampule). His condition continued to deteriorate, and by 2:00 p.m. his temperature soared to 42°C, he had convulsions, and he died. At the time JR’s condition began to deteriorate, Dr. Cabugao was out of town; before leaving, he made an endorsement and notified the resident doctor and nurses on duty that he would be on leave. The Death Certificate dated June 19, 2000, prepared by Dr. Cabugao, indicated the immediate cause as cardiorespiratory arrest; antecedent cause as metabolic encephalopathy; underlying cause as septicemia (acute appendicitis); and other significant condition contributing to death as cerebral aneurysm ruptured (?). No post-mortem examination was conducted on JR.

On February 1, 2001, an Information was filed against the accused for reckless imprudence resulting in homicide. The Information alleged that the accused, being attending physicians of JR, confederating and acting jointly with one another, failed through negligence, carelessness, and imprudence to perform immediate operation upon their patient of acute appendicitis. At their arraignment, both accused, duly assisted by counsel, pleaded not guilty. The RTC found that JR was under the medical care of the accused from admission until death; that the initial working diagnosis was acute appendicitis; that the CBC and ultrasound showed an inflammatory process or infection in the periumbilical region where the appendix could be located; and that the accused did not personally monitor JR, left monitoring to resident physicians still on training, failed to take steps to determine the real disease, and did not perform surgery. The CA similarly found that the accused neglected to monitor effectively and to act after the 24-hour observation period, and that Dr. Ynzon ruled out surgery despite the working diagnosis of acute appendicitis and the emergence of graver symptoms. These findings were material to the Supreme Court’s review of the sufficiency of the evidence against each physician.

• Cause of Accusation: Petitioners questioned whether the cause of accusation in the Information was the failure to perform immediate operation upon Rodolfo Palma, Jr. for acute appendicitis.
• Conspiracy: Petitioners questioned whether the Information accused both doctors of conspiracy and whether the appealed decision treated both accused doctors as conspirators.
• Dr. Cabugao’s Scope of Practice: Dr. Cabugao maintained that he was a general practitioner, not a surgeon; surgery was excluded from the limits of his practice; it was never his duty to operate on the patient, which was why he referred the patient to Dr. Ynzon.
• No Guarantee of Survival: Petitioners argued that the defense never stated that there was a guarantee that performing surgery would have saved the patient.
• Prosecution Evidence on Duty and Proximate Cause: Petitioners questioned whether the prosecution witnesses, including its expert witnesses, ever declared or testified that Dr. Cabugao had the duty to perform immediate operation on Rodolfo Palma, Jr., and whether they failed to show that the proximate cause of death was acute appendicitis.
• Expert Testimony on Dr. Cabugao’s Management: Petitioners questioned whether the prosecution’s expert witnesses ever questioned the management and care applied by Dr. Cabugao.
• Defense Experts: Petitioners argued that the defense expert witnesses were unanimous in approving the method of treatment applied by both accused doctors and declared that they would first place the patient under observation and would not perform immediate operation.
• Dr. Ynzon’s Conviction: Petitioners questioned whether Dr. Ynzon’s conviction was established with the required quantum of proof beyond reasonable doubt that the patient was specifically suffering from and died of acute appendicitis.
• Criminal Negligence: Petitioners questioned whether the failure to conduct appendectomy constituted criminal negligence.

• Cause of Accusation in the Information: Whether the cause of accusation in the Information is the failure to perform immediate operation upon Rodolfo Palma, Jr. for acute appendicitis.
• Conspiracy: Whether the Information accused both doctors of conspiracy and whether the appealed decision treated both accused doctors as conspirators.
• Dr. Cabugao’s Duty and Scope of Practice: Whether Dr. Cabugao, a general practitioner and not a surgeon, had the duty to perform the operation on the patient, or whether his referral to a surgeon excluded surgery from the limits of his practice.
• Proximate Cause and Prosecution Evidence: Whether the prosecution’s witnesses and expert witnesses established that Dr. Cabugao had the duty to perform immediate operation and that acute appendicitis was the proximate cause of death.
• Expert Testimony on Management: Whether the prosecution’s expert witnesses questioned Dr. Cabugao’s management and care, and whether the defense expert witnesses unanimously approved the treatment and would first place the patient under observation rather than perform immediate operation.
• Dr. Ynzon’s Conviction and Quantum of Proof: Whether Dr. Ynzon’s conviction was established beyond reasonable doubt that the patient was specifically suffering from and died of acute appendicitis.
• Criminal Negligence: Whether the failure to conduct appendectomy constituted criminal negligence.
• Sufficiency of Conviction for Reckless Imprudence Resulting in Homicide: Whether petitioners’ conviction of reckless imprudence resulting in homicide arising from alleged medical malpractice is supported by the evidence on record.

• Cause of Accusation in the Information: The conviction of Dr. Cabugao cannot stand on the charge as proved; the failure to perform an immediate operation did not establish his guilt because he was not a surgeon and had referred the patient to one. As to Dr. Ynzon, the evidence established reckless imprudence.
• Conspiracy: No. Conspiracy is inconsistent with the idea of a felony committed by means of culpa; the guilt of Dr. Ynzon did not necessarily establish the guilt of Dr. Cabugao.
• Dr. Cabugao’s Duty and Scope of Practice: No. Dr. Cabugao, a general practitioner, was not in a position to perform the required appendectomy; his referral of JR to Dr. Ynzon, a surgeon, was an exercise of precaution.
• Proximate Cause and Prosecution Evidence: The prosecution’s evidence established the need for surgery and the fatal consequences of unchecked appendicitis as to Dr. Ynzon, but it did not prove Dr. Cabugao’s criminal negligence beyond reasonable doubt.
• Expert Testimony on Management: The expert testimony did not establish that Dr. Cabugao breached the standard of care; it showed that the attending surgeon was primarily responsible for monitoring and deciding on surgery, and that Dr. Cabugao continued to issue orders and refer the patient.
• Dr. Ynzon’s Conviction and Quantum of Proof: Yes, the evidence established all elements of reckless imprudence as to Dr. Ynzon; however, his death pending appeal extinguished his criminal liability.
• Criminal Negligence: Yes, as to Dr. Ynzon, the failure to act on the need for appendectomy, coupled with failure to monitor and diagnose, constituted reckless imprudence; no such criminal negligence was proven against Dr. Cabugao.
• Sufficiency of Conviction for Reckless Imprudence Resulting in Homicide: The conviction of Dr. Cabugao was reversed for insufficiency of evidence; Dr. Ynzon’s criminal liability was extinguished by death, with civil liability subsisting.

• Cause of Accusation in the Information: The assigned errors were factual in nature; while findings of fact of the trial court and the Court of Appeals are generally binding and conclusive, the Court found the need to make an exception. Reckless imprudence consists of voluntarily doing or failing to do, without malice, an act from which material damage results by reason of an inexcusable lack of precaution. For Dr. Ynzon, all the requisites of the offense were clearly established. For Dr. Cabugao, however, the prosecution failed to prove the fact of the crime and the fact that he was the perpetrator beyond reasonable doubt. The failure to perform appendectomy could not be attributed to Dr. Cabugao because he was not a surgeon and was not in any position to perform the required appendectomy. Both lower courts bewailed the failure to perform appendectomy or to determine the source of infection, but the records failed to show that Dr. Cabugao could have performed the operation. Thus, the charge as proved did not support his conviction.

• Conspiracy: The Court held that conspiracy is inconsistent with the idea of a felony committed by means of culpa. Even if both accused appeared to be the attending physicians of JR during his hospital confinement, it cannot be said that the finding of guilt on Dr. Ynzon necessitates the same finding on Dr. Cabugao. To be found guilty of reckless imprudence resulting in homicide, it must be shown that both accused-doctors demonstrated an act executed without malice or criminal intent but with lack of foresight, carelessness, or negligence. The evidence on record clearly pointed to the reckless imprudence of Dr. Ynzon; the same cannot be said in Dr. Cabugao’s case.

• Dr. Cabugao’s Duty and Scope of Practice: Dr. Cabugao was not a surgeon but a general practitioner specializing in family medicine; even if he wanted to, he could not do an operation, much less an appendectomy on JR. It was precisely for this reason that he referred JR to Dr. Ynzon after he suspected appendicitis. Dr. Mateo, the prosecution’s expert witness, emphasized the role of the surgeon: the best person to monitor should be the first examiner, the best surgeon; it is incumbent on the surgeon attending to the case to observe within the period of observation because he is in the best position to observe sudden changes in the patient’s condition. Dr. Cabugao’s supervision did not cease upon his endorsement of his patient to the surgeon, but he exerted all efforts to monitor his patient and had no cause to doubt Dr. Ynzon’s competence and diligence. He frequently made orders on the administration of antibiotics and pain relievers and repeatedly instructed that JR be referred to Dr. Ynzon as he suspected appendicitis. The referral of JR to Dr. Ynzon, a surgeon, was an exercise of precaution as he knew that appendicitis was not within his scope of expertise. He was out of town when JR’s condition began to deteriorate, but before he left, he made an endorsement and notified the resident doctor and nurses on duty that he would be on leave. There was no evidence that Dr. Cabugao was negligent or lacked the necessary precaution in his performance of his duty as a family doctor.

• Proximate Cause and Prosecution Evidence: Dr. Mateo testified that he would perform surgery on JR and that if surgery were not done, the appendicitis would rupture, lead to generalized peritonitis and septicemia, and eventually result in death. Dr. Villaflor, a defense expert, testified that he would examine the patient thoroughly every 4 to 6 hours, and on cross-examination affirmed that to rule out acute appendicitis, surgery or operation must be done. From the testimonies of the expert witnesses, it was irrefutably proven that Dr. Ynzon failed to practice the degree of skill and care required in the treatment of his patient. As to Dr. Cabugao, however, there was no proof that he had the duty to operate or that his acts were the proximate cause of death. The Court found no evidence that Dr. Cabugao had been negligent or lacked the necessary precaution.

• Expert Testimony on Management: Whether a physician or surgeon has exercised the requisite degree of skill and care in the treatment of his patient is, in the generality of cases, a matter of expert opinion. The deference of courts to the expert opinions of qualified physicians stems from the realization that the latter possess unusual technical skills which laymen in most instances are incapable of intelligently evaluating. From the testimonies of the expert witnesses, it was irrefutably proven that Dr. Ynzon failed to practice that degree of skill and care required in the treatment of his patient. Dr. Ynzon revealed want of reasonable skill and care by neglecting to monitor effectively the developments and changes in JR’s condition during the observation period and to act upon the situation after the 24-hour period when his abdominal pain persisted and his condition worsened. He visited JR briefly only during regular rounds in the mornings and was not there during the crucial times on June 16, 2000, when JR’s condition started to deteriorate until his death. As the attending surgeon, he should be primarily responsible in monitoring the condition of JR, as he is in the best position considering his skills and experience to know if the patient’s condition had deteriorated. It was reckless and gross negligence of duty to relegate his personal responsibility to observe the condition of the patient. Acute appendicitis was the working diagnosis, and with the emergence of graver symptoms after the 24-hour observation, Dr. Ynzon ruled out surgery for no apparent reason. The records were devoid of any showing of any reasonable cause which would lead Dr. Ynzon to overrule appendectomy despite the initial diagnosis of appendicitis; neither was there any showing that he was entertaining another diagnosis or that he took appropriate steps towards another diagnosis. For Dr. Cabugao, the expert testimony did not show a breach of the standard of care; rather, it showed that he continued to issue orders and refer the patient.

• Dr. Ynzon’s Conviction and Quantum of Proof: The elements of reckless imprudence are: (1) that the offender does or fails to do an act; (2) that the doing or the failure to do that act is voluntary; (3) that it be without malice; (4) that material damage results from the reckless imprudence; and (5) that there is inexcusable lack of precaution on the part of the offender, taking into consideration his employment or occupation, degree of intelligence, physical condition, and other circumstances regarding persons, time and place. With respect to Dr. Ynzon, all the requisites of the offense were clearly established. The court a quo and the appellate court were one in concluding that Dr. Ynzon failed to observe the required standard of care expected from doctors. Whether or not a physician has committed an inexcusable lack of precaution in the treatment of his patient is to be determined according to the standard of care observed by other members of the profession in good standing under similar circumstances, bearing in mind the advanced state of the profession at the time of treatment or the present state of medical science. In accepting a case, a doctor in effect represents that, having the needed training and skill possessed by physicians and surgeons practicing in the same field, he will employ such training, care and skill in the treatment of his patients. He therefore has a duty to use at least the same level of care that any other reasonably competent doctor would use to treat a condition under the same circumstances. Dr. Ynzon did not display that degree of care and precaution demanded by the circumstances. However, while the case was pending appeal, Dr. Ynzon died on December 23, 2011 due to multiorgan failure. Under People vs. Bayotas, death of the accused pending appeal of his conviction extinguishes his criminal liability as well as the civil liability based solely thereon. Thus, his criminal liability was extinguished.

• Criminal Negligence: Among the elements constitutive of reckless imprudence, what is most central to a finding of guilt is the conclusive determination that the accused has exhibited, by his voluntary act without malice, an inexcusable lack of precaution. It is that which supplies the criminal intent so indispensable as to bring an act of mere negligence and imprudence under the operation of the penal law. A conscious indifference to the consequences of the conduct is all that is required from the standpoint of the frame of mind of the accused. Quasi-offenses penalize the mental attitude or condition behind the act, the dangerous recklessness, the lack of care or foresight, the imprudencia punible, unlike willful offenses which punish the intentional criminal act. This is precisely where the Court found Dr. Ynzon to be guilty: his seeming indifference to the deteriorating condition of JR, which caused him to fail to exercise the required precaution and eventually led to JR’s death. Dr. Cabugao did not exhibit such indifference or inexcusable lack of precaution.

• Sufficiency of Conviction for Reckless Imprudence Resulting in Homicide: Every criminal conviction requires the prosecution to prove two things: the fact of the crime, i.e., the presence of all the elements of the crime for which the accused stands charged, and the fact that the accused is the perpetrator of the crime. For Dr. Cabugao, the prosecution failed to prove these two things beyond reasonable doubt, and he was acquitted. For Dr. Ynzon, the evidence established the elements of reckless imprudence, but his death pending appeal extinguished his criminal liability. As to civil liability, the rules in People vs. Bayotas apply: death of the accused pending appeal extinguishes his criminal liability as well as the civil liability based solely thereon; the claim for civil liability survives if it may also be predicated on a source of obligation other than delict, such as law, contracts, quasi-contracts, or quasi-delicts under Article 1157 of the Civil Code; where the civil liability survives, an action for recovery may be pursued by way of a separate civil action subject to Section 1, Rule 111 of the 1985 Rules on Criminal Procedure as amended, and may be enforced against the executor/administrator or the estate of the accused depending on the source of obligation; and the private offended party need not fear forfeiture by prescription where the civil action was instituted together with the criminal action, as the statute of limitations is deemed interrupted during the pendency of the criminal case under Article 1155 of the Civil Code. Here, the death of Dr. Ynzon pending appeal extinguished his criminal liability, but the recovery of civil liability subsisted as the same was not based on delict but by contract and the reckless imprudence he was guilty of under Article 365 of the Revised Penal Code. A separate civil action may be enforced against the executor/administrator or the estate of the accused, depending on the source of obligation. Under Section 4, Rule 111 of the Rules on Criminal Procedure, the death of the accused after arraignment and during the pendency of the criminal action extinguishes the civil liability arising from the delict, but an independent civil action or one to enforce liability arising from other sources of obligation may be continued against the estate or legal representative of the accused after proper substitution. If the same act or omission arises from quasi-delict, a separate civil action must be filed against the executor or administrator of the estate under Section 1, Rule 87 of the Rules of Court. If the offended party desires to recover damages arising from contract, the separate civil action must be filed against the estate under Section 5, Rule 86 of the Rules of Court. The policy against double recovery requires that only one action be maintained for the same act or omission whether the action is brought against the executor or administrator or the estate; the heirs of JR must choose which of the available causes of action for damages they will bring.

• Reckless Imprudence Resulting in Homicide (Article 365, Revised Penal Code) — Reckless imprudence consists of voluntarily doing or failing to do, without malice, an act from which material damage results by reason of an inexcusable lack of precaution on the part of the person performing or failing to perform such act. Its elements are: (1) the offender does or fails to do an act; (2) the doing or failure to do the act is voluntary; (3) it is without malice; (4) material damage results from the reckless imprudence; and (5) there is inexcusable lack of precaution on the part of the offender, taking into consideration his employment or occupation, degree of intelligence, physical condition, and other circumstances regarding persons, time, and place. The Court applied this doctrine by finding all elements established as to Dr. Ynzon, whose failure to monitor and act on the acute appendicitis diagnosis constituted inexcusable lack of precaution, while Dr. Cabugao was acquitted because no such inexcusable lack of precaution was proven against him.

• Medical Malpractice and the Standard of Care — Whether a physician or surgeon has exercised the requisite degree of skill and care in the treatment of his patient is, in the generality of cases, a matter of expert opinion; courts defer to the expert opinions of qualified physicians because they possess unusual technical skills which laymen in most instances are incapable of intelligently evaluating. In accepting a case, a doctor in effect represents that, having the needed training and skill possessed by physicians and surgeons practicing in the same field, he will employ such training, care, and skill in the treatment of his patients. He therefore has a duty to use at least the same level of care that any other reasonably competent doctor would use to treat a condition under the same circumstances. The Court applied this doctrine by holding that Dr. Ynzon, the attending surgeon, failed to observe the required standard of care, while Dr. Cabugao, a general practitioner who referred the patient to a surgeon and continued monitoring, did not breach the standard.

• Conspiracy Inconsistent with Culpa — Conspiracy is inconsistent with the idea of a felony committed by means of culpa. A finding of guilt for reckless imprudence against one accused does not necessarily establish the guilt of a co-accused; it must be shown that each accused demonstrated an act executed without malice or criminal intent but with lack of foresight, carelessness, or negligence. The Court applied this doctrine by holding that the guilt of Dr. Ynzon did not automatically make Dr. Cabugao guilty, and that the evidence pointed only to Dr. Ynzon’s reckless imprudence.

• Death of Accused Pending Appeal (Bayotas Doctrine) — Death of the accused pending appeal of his conviction extinguishes his criminal liability as well as the civil liability based solely thereon, i.e., civil liability ex delicto in the strict sense. The claim for civil liability survives notwithstanding the death of the accused if it may also be predicated on a source of obligation other than delict, such as law, contracts, quasi-contracts, or quasi-delicts under Article 1157 of the Civil Code. Where the civil liability survives, an action for recovery may be pursued by way of a separate civil action subject to Section 1, Rule 111 of the 1985 Rules on Criminal Procedure as amended, and may be enforced against the executor/administrator or the estate of the accused depending on the source of obligation. The private offended party need not fear forfeiture by prescription where the civil action was instituted together with the criminal action, as the statute of limitations is deemed interrupted during the pendency of the criminal case under Article 1155 of the Civil Code. The Court applied this doctrine because Dr. Ynzon died on December 23, 2011 while the case was pending appeal; his criminal liability was extinguished, but his civil liability subsisted because it was not based solely on delict.

• Policy Against Double Recovery — Only one action may be maintained for the same act or omission, whether the action is brought against the executor or administrator or the estate of the accused. The Court applied this doctrine by holding that the heirs of JR must choose which of the available causes of action for damages they will bring.
