Juries Act 1962

An omission, error or irregularity by the Sheriff or any of his officers in the time and mode of service of a summons on a juror, or the summoning or return of a juror by a wrong name (if there is no question as to identity) is not a cause of challenge either to the array or to the juror.

A matter which might have been objected by way of challenge to the polls or to the array does not invalidate or affect any verdict in any case, civil or criminal, unless the objection is taken by way of challenge.
