BSA Section 80-Presumption As To Gazettes, Newspapers, And Other Documents

The Court shall presume the genuineness of every document purporting to be the Official Gazette, or to be a newspaper or journal, and of every document purporting to be a document directed by any law to be kept by any person, if such document is kept substantially in the form required by law and is produced from proper custody.

Explanation.—For the purposes of this section and section 92, document is said to be in proper custody if it is in the place in which, and looked after by the person with whom such document is required to be kept; but no custody is improper if it is proved to have had a legitimate origin, or if the circumstances of the particular case are such as to render that origin probable.
