Causation in Suicide: Clinical, Legal and Policy Interfaces

Abstract

Suicide presents courts, legislators, and policymakers with one of the most structurally difficult causation problems in contemporary law. Its complexity, extensively documented in clinical and epidemiological research, exceeds what existing legal causal standards were designed to accommodate. This article, written from the perspective of a legal practitioner engaged in interdisciplinary advocacy, examines the specific mechanisms by which legal and policy frameworks fail to engage adequately with the causal reality of suicide. Drawing on discussions from an interdisciplinary roundtable convened in April 2026, and situating those discussions within established legal principles from Indian and comparative jurisdictions, the article argues that reforms to causal standards in abetment prosecutions, investigative procedures, and preventive policy frameworks are both necessary and achievable. It identifies the structural deficiencies of existing legal doctrines, proximate causation, the novus actus interveniens doctrine, and the narrow construction of instigation under Section 306 IPC — and proposes a framework for interdisciplinary engagement as the necessary institutional infrastructure for just legal outcomes and evidence-based prevention policy.
