Proof of legal process

Any summons, rule, commitment, judgment, conviction, sentence, order or other written judicial act or document whatever, in any civil or criminal case, may be proved, in any legal proceeding whatever, against any person by producing a copy thereof certified by any judge or by the Registrar of the Supreme Court or, in the case of any other court, by any person performing functions analogous to those of a judge or the Registrar of the Supreme Court, without proof of the signature or official character of the person appearing to have certified the document.
