Proximate cause limits criminal negligence liability

The Supreme Court allowed the appeal and quashed the criminal case against a senior anaesthetist arising out of a post-operative death after piles surgery at a hospital in Kannur. The Court set aside the Kerala High Court’s order dated 16 October 2024 and discharged the appellant from the offences alleged in C.C. No. 501 of 2008.

Facts

The patient was admitted on 28 May 2002 and underwent surgery the next morning. He was shifted to the post-operative ward, where his condition deteriorated in the evening and he collapsed early the next day. The post-mortem found an 80% blockage in the left coronary artery, and the cause of death was recorded as acute coronary insufficiency.

The prosecution case was that the appellant, who was the senior anaesthetist, should have personally administered anesthesia post-surgery, but instead instructed the attending nurse to administer the analgesic sensorcaine. The prosecution linked that administration to the patient’s collapse and death.

Procedural history

An FIR was first lodged only against the surgeon. Later, a charge-sheet was filed against the surgeon, the appellant, and the nurse under Section 304-A and Section 34 IPC. Earlier quashing proceedings were partly successful, and an expert panel was constituted. A second charge-sheet followed, and the appellant’s later attempts to quash the proceedings before the Magistrate, Sessions Court, and High Court failed.

Reasoning

The Supreme Court focused on the legal requirements of Section 304-A IPC. It reiterated that criminal negligence requires a direct and proximate nexus between the negligent act and the death, described in the judgment as causa causans. A remote connection is not enough.

On the material before it, the Court found the chain of causation too attenuated. The deceased had a significant, undisclosed coronary blockage, and the immediate cause of death was acute coronary insufficiency. Even if the painkiller was not administered in the manner alleged, the Court held that the resulting sequence could not be fastened on the appellant as criminal liability for the death.

The judgment also noted the inconsistencies in the nurse’s statements and the reliance placed on the expert report. On the Court’s analysis, the prosecution material did not establish the kind of proximate causal link required to sustain a criminal trial against the appellant.

Holding

The appeal was allowed. The High Court order was quashed, and the criminal proceedings against the appellant in C.C. No. 501 of 2008 were quashed.

Practical takeaway

In medical negligence prosecutions under Section 304-A IPC, the Court will look for a direct and proximate causal link to death, not a remote or speculative chain of events.
