Supposition as a legal concept denotes conjecture without proof, not a substitute for evidence in legal reasoning. Supposition denotes a conjecture grounded in possibility or probability rather than proven fact; it operates as a non evidentiary assertion that a thing could or may have occurred without proof that it did. In legal terminology this concept is employed in explanatory materials, manuals, ready reckoners and reference guides to frame hypothetical scenarios, but it does not function as proof or a factual finding.
