OF INJUSTICE WITH REGARD TO THE PERSON OF THE WITNESS (FOUR ARTICLES)

We must now consider injustice with regard to the person of the witness. Under this head there are four points of inquiry:

(2) Whether the evidence of two or three witnesses suffices?

(3) Whether a man's evidence may be rejected without any fault on his part?

(4) Whether it is a mortal sin to bear false witness?
