Juries Act 1962

The Sheriff shall, before the time when a jury precept is required to be returned into the Court, prepare a list showing the names, in alphabetical order, and the descriptions, of the persons summoned in pursuance of the jury precept.

Where a single criminal trial is to commence in a jury district on a certain day, either:

all the jurors who attend in obedience to the summons from the jury district on that day shall constitute the jury panel for that trial; or

the Sheriff shall, by ballot, constitute a jury panel for the trial from amongst those who attend in obedience to the summons.

Where 2 or more criminal trials are to commence on a certain day, the Sheriff shall, before or on the day on which the jurors are summoned, by ballot, divide the jurors into separate panels and appropriate each panel to a trial.

Subject to section 37(2)(a), where jurors from any jury panel are not included in a jury for a trial the Sheriff may excuse them from further jury service on the day on which that trial commences, but they shall attend again, in accordance with their respective summonses, at a time and place directed by the Sheriff.
