accusare nemo se debet nisi coram Deo

no one ought to accuse himself except in the Presence of God


A legal maxim denoting that any accused person is entitled to make a plea of not guilty, and also that a witness is not obliged to give a response or submit a document that will incriminate himself. A very similar phrase is nemo tenetur se ipsum accusare "no one is bound to accuse himself". See right to silence.
