Every attorney, before his name is stricken off the roll, shall receive a written notice from the clerk of the supreme court, stating distinctly the grounds of complaint, or the charges exhibited against him, and he shall, after such notice, be heard in his defense, and allowed reasonable time to collect and prepare testimony for his justification. And every attorney whose name shall, at any time, be stricken from the roll by order of the court in manner aforesaid, shall be considered as though his name had never been written thereon, until such time as the said justices, in open court, shall authorize him to sign or subscribe the same.
