In Dubio, Sequendum Quod Tutius Est Law and Legal Definition
In dubio, sequendum quod tutius est is a legal maxim in Latin. It states that in a doubtful case, that course should be followed which is the safer one.
The following is an example of a case law referring to the maxim:
When a witness swears that he did a thing "two or three times," it means that he is morally certain of having done it twice, but not certain that he did it three times. If the witness be not morally certain of having done the thing more than twice, it would seem that a court should not feel legally certain that he did it more often; for if the witness himself be uncertain, how then can the court itself be certain; and "In dubio, sequendum quod tutius est."[State ex rel. Burleigh v. Savoie, 176 La. 115, 142 (La. 1933)].
