54.Section 29 permits the Lord President to intervene where the Lord President considers that a sheriff principal has exercised functions under section 27 or 28 in a way which is prejudicial to the efficient disposal of business in the sheriff courts, or is prejudicial to the efficient organisation or administration of those courts, or is otherwise against the public interest (subsection (1)). In such a case, the Lord President may rescind the exercise of the function by the sheriff principal and exercise the function (subsection (2)). This section makes equivalent provision to section 17A of the Sheriff Courts (Scotland) Act 1971.
