26 Certain documents to be laid before the House of Lords in case of appeal.
When any cause shall be carried by appeal to the House of Lords, the appellant shall lay before the house a copy, certified as authentic by the signature of one of the principal clerks of session, or of one of the assistants of the said clerks, for whom the principal clerks shall be responsible, of the whole records of the averments and pleas authenticated by the lord ordinary in manner above directed; and instead of such cases as are delivered at present to the House of Lords, each party shall present to the House of Lords a case containing a printed copy of the records as authenticated, and of the case presented to the Court of Session, if such there be; and they shall also be at liberty to annex a supplementary statement, containing an account of the further steps which have been taken in the cause since the record was completed, or the former cases prepared, and copies of the interlocutors or parts of interlocutors complained against, with a summary of such additional reasons as may be thought fit, set down in the form now used in the House of Lords.
