128. Where any person is arrested under rule 66 on a charge made by a personation agent that such person has committed the offence of personation or an offence under rule 102 and either such personation agent (or someone on the agent’s behalf) fails to appear before the court and support the charge, or the court acquits the person of having committed the offence and finds that the charge was made by the personation agent without reasonable or just cause, the court may, at the request of the person so charged but not otherwise, order the personation agent to pay to the person such sum not exceeding £500 as the court shall think proper by way of damages, and such sum when duly paid shall be accepted by the person so charged in full satisfaction of all claims by that person in respect of damages arising from the said charge and arrest and detention thereon.
