Illustration
A is at work with a hatchet; the head flies off and kills a man who is standing by. Here, if there was no want of proper caution on the part of A, his act is excusable and not an offence.

Court's Decision & Legal Precedent
At the stage of taking cognizance or quashing of charges in medical negligence cases, if the materials brought on record by the complainant, taken at face value and assumed to be wholly correct, disclose the existence of an offense or a prima facie case, the court cannot quash the proceedings merely because there are conflicting expert opinions or because the accused produces defense materials. The determination of which opinion ultimately prevails is a matter for the trial court upon consideration of all evidence. The High Court's jurisdiction under Section 482 CrPC to quash is limited and should be exercised only in rare and exceptional cases with unimpeachable evidence. A person professing to be a specialist must possess the requisite specialized expertise; lacking such expertise amounts to professional negligence. Criminal liability for medical negligence requires gross or reckless negligence, not mere error in diagnosis or judgment, distinguishing it from civil liability.
