Definition
A decision given 'in silence' — where a point of law was decided (or passed over) without being argued or considered by counsel or the court; such a decision does not create binding precedent on the point passed over in silence.
Sub silentio (Latin: 'under silence') is related to per incuriam but distinct from it. A decision is sub silentio on a point when that point was not raised or argued by counsel, not considered by the court, and the court's decision implies rather than states a position on it. The principle: a point of law that was not argued or decided is not a binding precedent on that point, even if the decision logically implies a position on it. The court's silence on a legal point — its failure to consider it — does not bind lower courts. A sub silentio decision might also arise where a court assumed a legal point (without deciding it) and proceeded on that assumption.
Statutory Definition
No statutory provision — sub silentio is a common law doctrine. Article 141 Constitution: 'law declared by the Supreme Court' — only law that was actually considered and declared is binding. The Supreme Court in <em>Sarla Mudgal v. Union of India</em> AIR 1995 SC 1531 distinguished between a binding precedent and a sub silentio decision: a point not argued or considered cannot be treated as settled law.
Etymology & Origin
Latin 'sub' (under, beneath) + 'silentio' (ablative of 'silentium' — silence). 'Under silence' — the point was passed over in silence, neither argued nor decided. The silence of the court on a point does not create binding law on that point.

Sub Silentio: The Unargued Point That Doesn’t Bind
Courts decide the cases before them — and they can only decide what has been argued. When a party fails to raise a legal point, when counsel fails to argue it, when the court fails to consider it — the legal question remains open. A court’s silence on a point, or its implicit assumption about a point without deciding it, does not create binding precedent. Later courts remain free to consider the point fresh.
Sub Silentio vs. Per Incuriam
(a) Per incuriam: The court was aware of the point but ignored a binding authority on it — the decision is wrong because it failed to apply known binding law. (b) Sub silentio: The court was never presented with the point — it was not argued, not considered, and not decided. The court's decision may logically imply a position on the point, but since the point was never addressed, the implication is not binding. In per incuriam, the court should have known; in sub silentio, the court was never asked. Both produce decisions that do not bind on the point in question — for different reasons.
Practical Importance
Sub silentio has significant practical importance in developing areas of law where precedents may have 'assumed' positions on ancillary points without deciding them. For example, courts may have routinely granted certain reliefs without considering whether they had jurisdiction to do so — the jurisdiction point was never raised. A subsequent litigant can argue that the prior decisions do not bind on the jurisdiction point because it was never argued or decided — it was passed sub silentio. This allows important legal questions to receive full consideration even if prior courts 'assumed' the answer without deciding.
“Sub silentio decisions are judicial gaps — points the law has not yet addressed even if courts have decided many cases that touch on them. The silence of a court on a legal question is not the law’s answer to that question. It is an invitation for the next litigant to raise it properly and get a considered decision.”
