Where in any civil proceedings a statement contained in a document is proposed to be given in evidence by virtue of section 2, 4 or 5 of this Act it may, subject to any rules of court, be proved by the production of that document or (whether or not that document is still in existence) by the production of a copy of that document, or of the material part thereof, authenticated in such manner as the court may approve.
For the purpose of deciding whether or not a statement is admissible in evidence by virtue of section 2, 4 or 5 of this Act, the court may draw any reasonable inference from the circumstances in which the statement was made or otherwise came into being or from any other circumstances, including, in the case of a statement contained in a document, the form and contents of that document.
In estimating the weight, if any, to be attached to a statement admissible in evidence by virtue of section 2, 3, 4 or 5 of this Act regard shall be had to all the circumstances from which any inference can reasonably be drawn as to the accuracy or otherwise of the statement and, in particular—
For the purpose of any enactment or rule of law or practice requiring evidence to be corroborated or regulating the manner in which uncorroborated evidence is to be treated—
If any person in a certificate tendered in evidence in civil proceedings by virtue of section 5(4) of this Act wilfully makes a statement material in those proceedings which he knows to be false or does not believe to be true, he shall be liable on conviction on indictment to imprisonment for a term not exceeding two years or a fine or both.
