28.This section makes provision for persons (who have sought approval for a qualifying abstraction or hold such an approval) to appeal to the sheriff against a relevant decision by the Scottish Ministers in relation to that approval. The sheriff may uphold or quash the decision, or vary it (by, for example, substituting a different period of validity of the approval, or removing or altering a condition attached to it). Any such appeal must be made within 21 days of the decision being intimated.
