Article 48 Summoning in exceptional circumstances
If it appears to the coroner that a jury will be, or probably will be, incomplete, the coroner may, if he thinks fit, require any persons who are in, or in the vicinity of, the place of the inquest to be summoned (without any written notice) for jury service up to the number needed (after allowing for any who may not be qualified under section 3A of the Act of 1887 and for excusals) to make up such number.
