Section 238 - What matters may be proved in connection with proved statement relevant under sections 40 to 50.

Whenever any statement admissible under section 40 to 50 of this Act, is proved, all matters may be proved either in order to contradict or to confirm it, or in order to impeach or confirm the credit of the person by whom it was made, which might have been proved if that person had been called as a witness and had denied upon cross-examination the truth of the matters suggested.
