fiat justitia ruat caelum
The maxim expresses the idea that a court must decide according to law and justice whatever the consequences, political or otherwise. It is associated in English law with Lord Mansfield's judgment in R v. Wilkes (1768), where he said the court must do its duty regardless of public clamour.
It is a statement of judicial independence rather than a rule applied to decide cases. Indian judges quote it when refusing to be swayed by public opinion, media pressure or the status of a party. It sits alongside salus populi suprema lex esto, which points the other way, towards the welfare of the people.
Example
Declining to consider the public outcry, the court recalled that fiat justitia ruat caelum: the accused's guilt must be proved by evidence, not by headlines.
