An action lies against an authorised person in respect of what the person does or omits to do—
in the purported execution of the person's duty as an authorised person exercising, by virtue of paragraph 3 of Schedule 5, functions of a tribunal, but
in relation to a matter not within the person's jurisdiction,
if, but only if, it is proved that the person acted in bad faith.
If an action is brought in a court in Scotland in circumstances in which subsection (1) or (2) provides that no action lies, the court in which the action is brought—
may, on the application of the defender, dismiss the action, and
if it does so, may find the person bringing the action liable in expenses.
If an action is brought in any other court in circumstances in which subsection (1) or (2) provides that no action lies, the court in which the action is brought—
may, on the application of the defendant, strike out the proceedings in the action, and
if it does so, may if it thinks fit order the person bringing the action to pay costs.
