Introduction:

In the case of Muralidharan v. State of Kerala, the Kerala High Court examined the applicability of the principle of res ipsa loquitur in criminal cases, emphasizing that the maxim is only an aid for evidence assessment and does not constitute a substantive rule of law or evidence. The case revolved around the conviction of a private bus driver for rash and negligent driving, leading to a fatal accident with a KSRTC bus. The Trial Court convicted the accused based on the principle of res ipsa loquitur, concluding that the private bus had gone to the wrong side of the road, causing the accident. On revision, the High Court overturned the conviction, holding that the prosecution had failed to prove the accused’s culpability beyond a reasonable doubt.

Arguments from Both Sides:

The prosecution contended that the accused drove the private bus in a rash and negligent manner, causing a collision with a KSRTC bus that resulted in the deaths of two passengers. They relied heavily on a document, Ext.P3, prepared by the investigating officer, which described the scene of the accident. The prosecution argued that the description in Ext.P3, along with the application of res ipsa loquitur, established that the accused was at fault for crossing to the wrong side of the road. Witnesses for the prosecution claimed the vehicle was driven at high speed, implying negligence. The prosecution also cited the Trial Court’s conclusion, which relied on the inherent presumption of fault under res ipsa loquitur when an accident occurs under unexplained circumstances.

The defense, however, argued that the prosecution failed to provide admissible evidence to substantiate the claim of rash and negligent driving. The accused contended that Ext.P3 was not proved through admissible evidence, as the investigating officer who prepared it did not testify about the place of occurrence or the circumstances of the accident. The defense further argued that high speed alone does not constitute rashness or negligence, emphasizing that the prosecution bore the burden of proving the accused’s guilt beyond a reasonable doubt. The defence also relied on the Supreme Court’s judgment in State of Karnataka v. Satish to underline the presumption of innocence in criminal cases and argued that the Trial Court misapplied res ipsa loquitur by using it as a basis for conviction without sufficient supporting evidence.

Court’s Judgment:

The Kerala High Court, presided over by Justice K Babu, critically analyzed the Trial Court’s reliance on res ipsa loquitur and its interpretation of Ext.P3. The Court noted that res ipsa loquitur is not a rule of substantive law or evidence but merely a principle to aid in the assessment of evidence in certain circumstances. Citing the Supreme Court’s decision in the State of Karnataka v. Satish, the Court reiterated that in criminal trials, the burden of proof always rests on the prosecution, and there is a presumption of innocence in favour of the accused until proven otherwise. The Court emphasized that criminal liability cannot be presumed without clear, admissible evidence, except in cases involving statutory exceptions.

The High Court observed that the prosecution failed to prove the contents of Ext.P3 through admissible evidence, as the investigating officer did not testify regarding the scene of the accident. The Court noted that the Trial Court had misread the evidence by concluding that the private bus crossed to the wrong side of the road based solely on Ext.P3, without corroborating testimony or proof. Furthermore, the Court found that witness statements merely indicated that the vehicle was driven at high speed, which, by itself, does not satisfy the legal requirements of rash and negligent driving.

The Court also referred to its earlier judgment in Kesava Pillai v. State of Kerala, where it had held that res ipsa loquitur is applicable in criminal cases only as an aid to evaluate evidence, and not as an independent basis for conviction. Applying this principle, the Court concluded that the prosecution had failed to establish the accused’s guilt beyond a reasonable doubt. The High Court pointed out that both the Trial Court and the Sessions Court had arrived at unreasonable conclusions based on a misreading of the records and a misapplication of the law.

In setting aside the conviction, the High Court underscored the fundamental principles of criminal jurisprudence, particularly the requirement for the prosecution to prove every element of the offence beyond a reasonable doubt. The Court also criticized the Trial Court for relying on a document that was not substantiated by admissible evidence and for misapplying res ipsa loquitur as a substantive basis for conviction. Ultimately, the High Court acquitted the accused, finding that the prosecution had failed to discharge its burden of proof.
