Solemn procedure – Adjournment of trial diet – Time bar – Twelve-month rule. High Court of Justiciary: Passing bills of advocation by four appellants complaining against a sheriff's decisions ex proprio motu adjourning a trial diet to a future assize and thereafter granting a motion for an extension of time, the court held that the decision ex proprio motu to adjourn the trial diet was flawed and in any event the sheriff ought to have exercised his discretion and refused the extension.
